                  GNU LESSER GENERAL PUBLIC LICENSE
                       Version 2.1, February 1999
 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 [This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]
                            Preamble
  The licenses for most software are designed to take away your
 freedom to share and change it.  By contrast, the GNU General Public
 Licenses are intended to guarantee your freedom to share and change
 free software--to make sure the software is free for all its users.
  This license, the Lesser General Public License, applies to some
 specially designated software packages--typically libraries--of the
 Free Software Foundation and other authors who decide to use it.  You
 can use it too, but we suggest you first think carefully about whether
 this license or the ordinary General Public License is the better
 strategy to use in any particular case, based on the explanations below.
  When we speak of free software, we are referring to freedom of use,
 not price.  Our General Public Licenses are designed to make sure that
 you have the freedom to distribute copies of free software (and charge
 for this service if you wish); that you receive source code or can get
 it if you want it; that you can change the software and use pieces of
 it in new free programs; and that you are informed that you can do
 these things.
  To protect your rights, we need to make restrictions that forbid
 distributors to deny you these rights or to ask you to surrender these
 rights.  These restrictions translate to certain responsibilities for
 you if you distribute copies of the library or if you modify it.
  For example, if you distribute copies of the library, whether gratis
 or for a fee, you must give the recipients all the rights that we gave
 you.  You must make sure that they, too, receive or can get the source
 code.  If you link other code with the library, you must provide
 complete object files to the recipients, so that they can relink them
 with the library after making changes to the library and recompiling
 it.  And you must show them these terms so they know their rights.
  We protect your rights with a two-step method: (1) we copyright the
 library, and (2) we offer you this license, which gives you legal
 permission to copy, distribute and/or modify the library.
  To protect each distributor, we want to make it very clear that
 there is no warranty for the free library.  Also, if the library is
 modified by someone else and passed on, the recipients should know
 that what they have is not the original version, so that the original
 author's reputation will not be affected by problems that might be
 introduced by others.
  Finally, software patents pose a constant threat to the existence of
 any free program.  We wish to make sure that a company cannot
 effectively restrict the users of a free program by obtaining a
 restrictive license from a patent holder.  Therefore, we insist that
 any patent license obtained for a version of the library must be
 consistent with the full freedom of use specified in this license.
  Most GNU software, including some libraries, is covered by the
 ordinary GNU General Public License.  This license, the GNU Lesser
 General Public License, applies to certain designated libraries, and
 is quite different from the ordinary General Public License.  We use
 this license for certain libraries in order to permit linking those
 libraries into non-free programs.
  When a program is linked with a library, whether statically or using
 a shared library, the combination of the two is legally speaking a
 combined work, a derivative of the original library.  The ordinary
 General Public License therefore permits such linking only if the
 entire combination fits its criteria of freedom.  The Lesser General
 Public License permits more lax criteria for linking other code with
 the library.
  We call this license the "Lesser" General Public License because it
 does Less to protect the user's freedom than the ordinary General
 Public License.  It also provides other free software developers Less
 of an advantage over competing non-free programs.  These disadvantages
 are the reason we use the ordinary General Public License for many
 libraries.  However, the Lesser license provides advantages in certain
 special circumstances.
  For example, on rare occasions, there may be a special need to
 encourage the widest possible use of a certain library, so that it becomes
 a de-facto standard.  To achieve this, non-free programs must be
 allowed to use the library.  A more frequent case is that a free
 library does the same job as widely used non-free libraries.  In this
 case, there is little to gain by limiting the free library to free
 software only, so we use the Lesser General Public License.
  In other cases, permission to use a particular library in non-free
 programs enables a greater number of people to use a large body of
 free software.  For example, permission to use the GNU C Library in
 non-free programs enables many more people to use the whole GNU
 operating system, as well as its variant, the GNU/Linux operating
 system.
  Although the Lesser General Public License is Less protective of the
 users' freedom, it does ensure that the user of a program that is
 linked with the Library has the freedom and the wherewithal to run
 that program using a modified version of the Library.
  The precise terms and conditions for copying, distribution and
 modification follow.  Pay close attention to the difference between a
 "work based on the library" and a "work that uses the library".  The
 former contains code derived from the library, whereas the latter must
 be combined with the library in order to run.
                  GNU LESSER GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  0. This License Agreement applies to any software library or other
 program which contains a notice placed by the copyright holder or
 other authorized party saying it may be distributed under the terms of
 this Lesser General Public License (also called "this License").
 Each licensee is addressed as "you".
  A "library" means a collection of software functions and/or data
 prepared so as to be conveniently linked with application programs
 (which use some of those functions and data) to form executables.
  The "Library", below, refers to any such software library or work
 which has been distributed under these terms.  A "work based on the
 Library" means either the Library or any derivative work under
 copyright law: that is to say, a work containing the Library or a
 portion of it, either verbatim or with modifications and/or translated
 straightforwardly into another language.  (Hereinafter, translation is
 included without limitation in the term "modification".)
  "Source code" for a work means the preferred form of the work for
 making modifications to it.  For a library, complete source code means
 all the source code for all modules it contains, plus any associated
 interface definition files, plus the scripts used to control compilation
 and installation of the library.
  Activities other than copying, distribution and modification are not
 covered by this License; they are outside its scope.  The act of
 running a program using the Library is not restricted, and output from
 such a program is covered only if its contents constitute a work based
 on the Library (independent of the use of the Library in a tool for
 writing it).  Whether that is true depends on what the Library does
 and what the program that uses the Library does.
  1. You may copy and distribute verbatim copies of the Library's
 complete source code as you receive it, in any medium, provided that
 you conspicuously and appropriately publish on each copy an
 appropriate copyright notice and disclaimer of warranty; keep intact
 all the notices that refer to this License and to the absence of any
 warranty; and distribute a copy of this License along with the
 Library.
  You may charge a fee for the physical act of transferring a copy,
 and you may at your option offer warranty protection in exchange for a
 fee.
  2. You may modify your copy or copies of the Library or any portion
 of it, thus forming a work based on the Library, and copy and
 distribute such modifications or work under the terms of Section 1
 above, provided that you also meet all of these conditions:
    a) The modified work must itself be a software library.
    b) You must cause the files modified to carry prominent notices
    stating that you changed the files and the date of any change.
    c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.
    d) If a facility in the modified Library refers to a function or a
    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.
    (For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)
 These requirements apply to the modified work as a whole.  If
 identifiable sections of that work are not derived from the Library,
 and can be reasonably considered independent and separate works in
 themselves, then this License, and its terms, do not apply to those
 sections when you distribute them as separate works.  But when you
 distribute the same sections as part of a whole which is a work based
 on the Library, the distribution of the whole must be on the terms of
 this License, whose permissions for other licensees extend to the
 entire whole, and thus to each and every part regardless of who wrote
 it.
 Thus, it is not the intent of this section to claim rights or contest
 your rights to work written entirely by you; rather, the intent is to
 exercise the right to control the distribution of derivative or
 collective works based on the Library.
 In addition, mere aggregation of another work not based on the Library
 with the Library (or with a work based on the Library) on a volume of
 a storage or distribution medium does not bring the other work under
 the scope of this License.
  3. You may opt to apply the terms of the ordinary GNU General Public
 License instead of this License to a given copy of the Library.  To do
 this, you must alter all the notices that refer to this License, so
 that they refer to the ordinary GNU General Public License, version 2,
 instead of to this License.  (If a newer version than version 2 of the
 ordinary GNU General Public License has appeared, then you can specify
 that version instead if you wish.)  Do not make any other change in
 these notices.
  Once this change is made in a given copy, it is irreversible for
 that copy, so the ordinary GNU General Public License applies to all
 subsequent copies and derivative works made from that copy.
  This option is useful when you wish to copy part of the code of
 the Library into a program that is not a library.
  4. You may copy and distribute the Library (or a portion or
 derivative of it, under Section 2) in object code or executable form
 under the terms of Sections 1 and 2 above provided that you accompany
 it with the complete corresponding machine-readable source code, which
 must be distributed under the terms of Sections 1 and 2 above on a
 medium customarily used for software interchange.
  If distribution of object code is made by offering access to copy
 from a designated place, then offering equivalent access to copy the
 source code from the same place satisfies the requirement to
 distribute the source code, even though third parties are not
 compelled to copy the source along with the object code.
  5. A program that contains no derivative of any portion of the
 Library, but is designed to work with the Library by being compiled or
 linked with it, is called a "work that uses the Library".  Such a
 work, in isolation, is not a derivative work of the Library, and
 therefore falls outside the scope of this License.
  However, linking a "work that uses the Library" with the Library
 creates an executable that is a derivative of the Library (because it
 contains portions of the Library), rather than a "work that uses the
 library".  The executable is therefore covered by this License.
 Section 6 states terms for distribution of such executables.
  When a "work that uses the Library" uses material from a header file
 that is part of the Library, the object code for the work may be a
 derivative work of the Library even though the source code is not.
 Whether this is true is especially significant if the work can be
 linked without the Library, or if the work is itself a library.  The
 threshold for this to be true is not precisely defined by law.
  If such an object file uses only numerical parameters, data
 structure layouts and accessors, and small macros and small inline
 functions (ten lines or less in length), then the use of the object
 file is unrestricted, regardless of whether it is legally a derivative
 work.  (Executables containing this object code plus portions of the
 Library will still fall under Section 6.)
  Otherwise, if the work is a derivative of the Library, you may
 distribute the object code for the work under the terms of Section 6.
 Any executables containing that work also fall under Section 6,
 whether or not they are linked directly with the Library itself.
  6. As an exception to the Sections above, you may also combine or
 link a "work that uses the Library" with the Library to produce a
 work containing portions of the Library, and distribute that work
 under terms of your choice, provided that the terms permit
 modification of the work for the customer's own use and reverse
 engineering for debugging such modifications.
  You must give prominent notice with each copy of the work that the
 Library is used in it and that the Library and its use are covered by
 this License.  You must supply a copy of this License.  If the work
 during execution displays copyright notices, you must include the
 copyright notice for the Library among them, as well as a reference
 directing the user to the copy of this License.  Also, you must do one
 of these things:
    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.  (It is understood
    that the user who changes the contents of definitions files in the
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)
    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.
    c) Accompany the work with a written offer, valid for at
    least three years, to give the same user the materials
    specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.
    d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.
    e) Verify that the user has already received a copy of these
    materials or that you have already sent this user a copy.
  For an executable, the required form of the "work that uses the
 Library" must include any data and utility programs needed for
 reproducing the executable from it.  However, as a special exception,
 the materials to be distributed need not include anything that is
 normally distributed (in either source or binary form) with the major
 components (compiler, kernel, and so on) of the operating system on
 which the executable runs, unless that component itself accompanies
 the executable.
  It may happen that this requirement contradicts the license
 restrictions of other proprietary libraries that do not normally
 accompany the operating system.  Such a contradiction means you cannot
 use both them and the Library together in an executable that you
 distribute.
  7. You may place library facilities that are a work based on the
 Library side-by-side in a single library together with other library
 facilities not covered by this License, and distribute such a combined
 library, provided that the separate distribution of the work based on
 the Library and of the other library facilities is otherwise
 permitted, and provided that you do these two things:
    a) Accompany the combined library with a copy of the same work
    based on the Library, uncombined with any other library
    facilities.  This must be distributed under the terms of the
    Sections above.
    b) Give prominent notice with the combined library of the fact
    that part of it is a work based on the Library, and explaining
    where to find the accompanying uncombined form of the same work.
  8. You may not copy, modify, sublicense, link with, or distribute
 the Library except as expressly provided under this License.  Any
 attempt otherwise to copy, modify, sublicense, link with, or
 distribute the Library is void, and will automatically terminate your
 rights under this License.  However, parties who have received copies,
 or rights, from you under this License will not have their licenses
 terminated so long as such parties remain in full compliance.
  9. You are not required to accept this License, since you have not
 signed it.  However, nothing else grants you permission to modify or
 distribute the Library or its derivative works.  These actions are
 prohibited by law if you do not accept this License.  Therefore, by
 modifying or distributing the Library (or any work based on the
 Library), you indicate your acceptance of this License to do so, and
 all its terms and conditions for copying, distributing or modifying
 the Library or works based on it.
  10. Each time you redistribute the Library (or any work based on the
 Library), the recipient automatically receives a license from the
 original licensor to copy, distribute, link with or modify the Library
 subject to these terms and conditions.  You may not impose any further
 restrictions on the recipients' exercise of the rights granted herein.
 You are not responsible for enforcing compliance by third parties with
 this License.
  11. If, as a consequence of a court judgment or allegation of patent
 infringement or for any other reason (not limited to patent issues),
 conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot
 distribute so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you
 may not distribute the Library at all.  For example, if a patent
 license would not permit royalty-free redistribution of the Library by
 all those who receive copies directly or indirectly through you, then
 the only way you could satisfy both it and this License would be to
 refrain entirely from distribution of the Library.
 If any portion of this section is held invalid or unenforceable under any
 particular circumstance, the balance of the section is intended to apply,
 and the section as a whole is intended to apply in other circumstances.
 It is not the purpose of this section to induce you to infringe any
 patents or other property right claims or to contest validity of any
 such claims; this section has the sole purpose of protecting the
 integrity of the free software distribution system which is
 implemented by public license practices.  Many people have made
 generous contributions to the wide range of software distributed
 through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing
 to distribute software through any other system and a licensee cannot
 impose that choice.
 This section is intended to make thoroughly clear what is believed to
 be a consequence of the rest of this License.
  12. If the distribution and/or use of the Library is restricted in
 certain countries either by patents or by copyrighted interfaces, the
 original copyright holder who places the Library under this License may add
 an explicit geographical distribution limitation excluding those countries,
 so that distribution is permitted only in or among countries not thus
 excluded.  In such case, this License incorporates the limitation as if
 written in the body of this License.
  13. The Free Software Foundation may publish revised and/or new
 versions of the Lesser General Public License from time to time.
 Such new versions will be similar in spirit to the present version,
 but may differ in detail to address new problems or concerns.
 Each version is given a distinguishing version number.  If the Library
 specifies a version number of this License which applies to it and
 "any later version", you have the option of following the terms and
 conditions either of that version or of any later version published by
 the Free Software Foundation.  If the Library does not specify a
 license version number, you may choose any version ever published by
 the Free Software Foundation.
  14. If you wish to incorporate parts of the Library into other free
 programs whose distribution conditions are incompatible with these,
 write to the author to ask for permission.  For software which is
 copyrighted by the Free Software Foundation, write to the Free
 Software Foundation; we sometimes make exceptions for this.  Our
 decision will be guided by the two goals of preserving the free status
 of all derivatives of our free software and of promoting the sharing
 and reuse of software generally.
                            NO WARRANTY
  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
 DAMAGES.
                     END OF TERMS AND CONDITIONS
           How to Apply These Terms to Your New Libraries
  If you develop a new library, and you want it to be of the greatest
 possible use to the public, we recommend making it free software that
 everyone can redistribute and change.  You can do so by permitting
 redistribution under these terms (or, alternatively, under the terms of the
 ordinary General Public License).
  To apply these terms, attach the following notices to the library.  It is
 safest to attach them to the start of each source file to most effectively
 convey the exclusion of warranty; and each file should have at least the
 "copyright" line and a pointer to where the full notice is found.
    <one line to give the library's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Lesser General Public
    License as published by the Free Software Foundation; either
    version 2.1 of the License, or (at your option) any later version.
    This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU

    You should have received a copy of the GNU Lesser General Public
    License along with this library; if not, write to the Free Software
    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301
    USA
 Also add information on how to contact you by electronic and paper mail.
 You should also get your employer (if you work as a programmer) or your
 school, if any, to sign a "copyright disclaimer" for the library, if
 necessary.  Here is a sample; alter the names:
  Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random
  Hacker.

-### Docking everywhere - no central widget
+[![Video Advanced Docking](doc/advanced-docking_video.png)](https://www.youtube.com/watch?v=7pdNfafg3Qc)
-There is no central widget like in the Qt docking system. You can dock on every
+
-border of the main window or you can dock into each dock area - so you are
+## New and Noteworthy
-free to dock almost everywhere.
+
-

-\
+#### Tabs at Bottom
-![Dropping widgets](doc/preview-dragndrop_dark.png)
+
-
+A new global dock manager flag `TabsAtBottom` has been added to configuration flags. This flag allows to configure if the tabs of dock areas are shown at the top (default) or at the bottom of the respective container.
-### Docking inside floating windows
+
-There is no difference between the main window and a floating window. Docking
+If the flag is set, tabs will be shown at the bottom instead of in the title bar.
-into floating windows is supported.

-
+Release [4.1](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/latest) significantly improves the Auto-Hide functionality and also brings improvements
-### Grouped dragging
+for Drag and Drop of dock widgets into dock area tabs. These are the highlights of the new version:
-When dragging the titlebar of a dock, all the tabs that are tabbed with it are 
+
-going to be dragged. So you can move complete groups of tabbed widgets into
+#### Drag & Drop to Auto-Hide
-a floating widget or from one dock area to another one.
+
-
+Now you can easily drag any dock widget or any floating widget to the
-![Grouped dragging](doc/grouped-dragging.png)\
+borders of a window to pin it as a auto-hide tab in one of the 4 sidebars.
-\
+If you drag a dock widget close the one of the four window borders, special

-### Perspectives for fast switching of the complete main window layout

-main window layout.
+
-
+If you drag a dock widget or dock area into a sidebar, then you even have
-![Perspective](doc/perspectives.png)\
+control over where tabs are inserted. Simply drag your mouse over a specific
-\
+auto-hide tab, and your dragged dock widget will be inserted before this tab.
-![Perspective](doc/perspectives_dark.png)
+Drag to the sidebar area behind the last tab, and the dragged widget will be
-
+appended as last tab. In the following screen capture, the **Image Viewer 1** will

+
-## Build
+![Auo-Hide tab insert order](doc/AutoHide_Tab_Insert_Order.gif)
-Open the `ads.pro` with QtCreator and start the build, that's it.
+
-You can run the demo project and test it yourself.
+#### Auto-Hide Tab Insertion Order
-
+
-## Getting started / Example
+It is also possible to drag Auto-Hide tabs to a new auto-hide position.
-The following example shows the minimum code required to use the advanced Qt docking system.
+That means, you can drag them to a different border or sidebar:
-
+
-*MainWindow.h*
+![Auto-Hide change sidebar](doc/AutoHide_Change_Sidebar.gif)
-
+
-```cpp
+#### Auto-Hide Tab Sorting
-#include <QMainWindow>
+
-#include "DockManager.h"
+You can drag Auto-Hide tabs to a new position in the current sidebar
-
+to sort them:
-namespace Ui {
+
-class MainWindow;
+![Auo-Hide sort tabs](doc/AutoHide_Sort_Tabs.gif)
-}
+
-
+#### Auto-Hide Drag to Float / Dock
-class MainWindow : public QMainWindow
+
-{
+But that is not all. You can also simply move Auto-Hide tabs to another
-    Q_OBJECT
+floating widget or dock them via drag and drop:
-
+
-public:
+![Auo-Hide drag to float or dock](doc/AutoHide_Drag_to_Float_or_Dock.gif)
-    explicit MainWindow(QWidget *parent = 0);
+
-    ~MainWindow();
+#### Auto-Hide Context Menu
-
+
-private:
+All Auto-Hide tabs now have a context menu, that provides all the functionality
-    Ui::MainWindow *ui;
+that you know from Dock widget tabs. With the **Pin To...** item from the
-    
+context menu it is very easy to move an Auto-Hide tab to a different Auto-Hide
-    // The main container for docking
+sidebar:
-    ads::CDockManager* m_DockManager;
+
-};
+![Auo-Hide context menu](doc/AutoHide_Context_Menu.png)
-```
+
-*MainWindow.cpp*
+#### Dock Area Tab Insert Order
-```cpp
+
-#include "MainWindow.h"
+And last but not least the new version also improves the docking of widgets
-#include "ui_MainWindow.h"
+into the tabs of a Dock area. Just as with Auto-Hide tabs, you can now determine the position at which a tab is inserted by moving the mouse over an already existing tab (insertion before the tab) or behind the last tab

 ### Docking everywhere - no central widget
 There is no central widget like in the Qt docking system. You can dock on every
 border of the main window or you can dock into each dock area - so you are
 free to dock almost everywhere.
 ![Dropping widgets](doc/preview-dragndrop.png)
 ![Dropping widgets](doc/preview-dragndrop_dark.png)
 ### Docking inside floating windows
 There is no difference between the main window and a floating window. Docking
 into floating windows is supported.
 ![Docking inside floating windows](doc/floating-widget-dragndrop.png)
 ![Docking inside floating windows](doc/floating-widget-dragndrop_dark.png)
 ### Grouped dragging
 When dragging the titlebar of a dock, all the tabs that are tabbed with it are
 going to be dragged. So you can move complete groups of tabbed widgets into
 a floating widget or from one dock area to another one.
 ![Grouped dragging](doc/grouped-dragging.gif)
 ![Grouped dragging](doc/grouped-dragging_dark.png)
 ### Perspectives for fast switching of the complete main window layout
 A perspective defines the set and layout of dock windows in the main
 window. You can save the current layout of the dockmanager into a named
 perspective to make your own custom perspective. Later you can simply
 select a perspective from the perspective list to quickly switch the complete
 main window layout.
 ![Perspective](doc/perspectives.gif)
 ![Perspective](doc/perspectives_dark.png)
 ### Opaque and non-opaque splitter resizing
 The advanced docking system uses standard QSplitters as resize separators and thus supports opaque and non-opaque resizing functionality of QSplitter. In some rare cases, for very complex widgets or on slow machines resizing via separator on the fly may cause flicking and glaring of rendered content inside a widget. The global dock manager flag `OpaqueSplitterResize` configures the resizing behaviour of the splitters. If this flag is set, then widgets are resized dynamically (opaquely) while interactively moving the splitters.
 ![Opaque resizing](doc/opaque_resizing.gif)
 If this flag is cleared, the widget resizing is deferred until the mouse button is released - this is some kind of lazy resizing separator.
 ![Non-opaque resizing](doc/non_opaque_resizing.gif)
 ### Cancelable docking process
 In contrast to the standard Qt docking system, docking with the ADS works more like a drag & drop operation. That means, the dragged dock widget or dock area is not undocked immediately. Instead, a drag preview widget is created and dragged around to indicate the future position of the dock widget or dock area. The actual dock operation is only executed when the mouse button is released. That makes it possible, to cancel an active drag operation with the escape key.
 The drag preview widget can be configured by a number of global dock manager flags:
 - `DragPreviewIsDynamic`: if this flag is enabled, the preview will be adjusted dynamically to the drop area
 - `DragPreviewShowsContentPixmap`: the created drag preview window shows a static copy of the content of the dock widget / dock are that is dragged
 - `DragPreviewHasWindowFrame`: this flag configures if the drag preview is frameless like a QRubberBand or looks like a real window
 ### Tab-menu for easy handling of many tabbed dock widgets
 Tabs are a good way to quickly switch between dockwidgets in a dockarea. However, if the number of dockwidgets in a dockarea is too large, this may affect the usability of the tab bar. To keep track in this situation, you can use the tab menu. The menu allows you to quickly select the dockwidget you want to activate from a drop down menu.
 ![Tab menu](doc/tab_menu.gif)
 ### Many different ways to detach dock widgets
 You can detach dock widgets and also dock areas in the following ways:
 - by dragging the dock widget tab or the dock area title bar
 - by double clicking the tab or title bar
 - by using the detach menu entry from the tab and title bar drop down menu
 ### Supports deletion of dynamically created dock widgets
 Normally clicking the close button of a dock widget will just hide the widget and the user can show it again using the toggleView() action of the dock widget. This is meant for user interfaces with a static amount of widgets. But the advanced docking system also supports dynamic dock widgets that will get deleted on close. If you set the dock widget flag `DockWidgetDeleteOnClose` for a certain dock widget, then it will be deleted as soon as you close this dock widget. This enables the implementation of user interfaces with dynamically created editors, like in word processing applications or source code development tools.
 ### Auto-Hide Functionality
 The 4.0 release of ADS added the new **Auto-Hide** feature. Thanks to the
 [initial contribution](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/pull/452) by [Ahmad Syarifuddin](https://github.com/SyarifFakhri) it was
 possible to close this long standing [feature request](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/147). The "Auto Hide" feature
 allows to display more information using less screen space by hiding or showing
 windows pinned to one of the four dock container borders.
 ![Auto-Hide Movie](doc/AutoHide_Movie.gif)
 The Advanced Docking
 System supports "Auto-Hide" functionality for **all** dock containers - that means,
 for the main window and for each floating widget. Here is short list of all
 auto hide features:
 - supported for the main window and all floating dock containers
 - supports showing and hiding via mouse click or mouse hover
 - respects opaque / non opaque splitter resizing flag
 - context menu for pinning a dock widget or a complete dock area to a certain border
 - configuration option to configure if the pin button should pin the current
  dock widget tab or a complete dock area
 - click the pin button holding the Ctrl key to pin a complete dock area
 - fully CSS styleable
 - backward compatible state file format - is is possible to load older dock manager
  state files without auto hide support and older versions can load the new state
  files with Auto-Hide state information
 More about the auto hide configuration options in the [online documentation...](doc/user-guide.md#auto-hide-configuration-flags)
 ## Python Bindings

 ## Tested Compatible Environments
 ### Supported Qt Versions
 The library supports **Qt5** and **Qt6**.
 ### Windows
 Windows 10 / 11 [![Build status](https://ci.appveyor.com/api/projects/status/qcfb3cy932jw9mpy/branch/master?svg=true)](https://ci.appveyor.com/project/githubuser0xFFFF/qt-advanced-docking-system/branch/master)
 [![windows-builds](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/actions/workflows/windows-cmake.yml/badge.svg?branch=master)](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/actions/workflows/windows-cmake.yml)
 The library was developed on and for Windows. It is used in a commercial Windows application and is therefore constantly tested.
 ### macOS
 The application can be compiled for macOS. A user reported, that the library works on macOS. If have not tested it.
 ![Advanced Docking on macOS](doc/macos.png)
 ### Linux
 [![Build status](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/workflows/linux-builds/badge.svg)](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/actions?query=workflow%3Alinux-builds)
 Unfortunately, there is no such thing as a Linux operating system. Linux is a heterogeneous environment with a variety of different distributions. So it is not possible to support "Linux" like it is possible for Windows. It is only possible to support and test a small subset of Linux distributions. The library can be compiled for and has been developed and tested with some Linux distributions. Depending on the used window manager or compositor, dock widgets
 with native title bars are supported or not. If native title bars are not supported,
 the library switches to `QWidget` based title bars.
 - **Kubuntu 18.04 and 19.10** - uses KWin - no native title bars
 - **Ubuntu 18.04, 19.10 and 20.04** - native title bars are supported
 - **Ubuntu 22.04** - uses Wayland -> no native title bars
 There are some requirements for the Linux distribution that have to be met:
 - an X server that supports ARGB visuals and a compositing window manager. This is required to display the translucent dock overlays ([https://doc.qt.io/qt-5/qwidget.html#creating-translucent-windows](https://doc.qt.io/qt-5/qwidget.html#creating-translucent-windows)). If your Linux distribution does not support this, or if you disable this feature, you will very likely see issue [#95](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/95).
 - Wayland is not properly supported by Qt yet. If you use Wayland, then you should set the session type to x11: `XDG_SESSION_TYPE=x11 ./AdvancedDockingSystemDemo`. You will find more details about this in issue [#288](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/288).

 Screenshot Ubuntu:
 ![Advanced Docking on Ubuntu Linux](doc/linux_ubuntu_1910.png)
 ## Build
 The Linux build requires private header files. Make sure that they are installed.
 The library uses SVG icons, so ensure that Qt SVG support is installed. The demo
 application creates a `QQuickWidget` for testing, so ensure that the required
 libraries are installed.
 ### Qt5 on Ubuntu 18.04 or 20.04
 ```bash
 sudo apt install qt5-default qtbase5-private-dev
 ```
 ### Qt5 on Ubuntu 22.04
 ```bash
 sudo apt install qtbase5-dev qtbase5-private-dev qtbase5-dev-tools libqt5svg5 libqt5qml5 qtdeclarative5-dev
 ```
 ### Qt6 on Ubuntu 22.04
 ```bash
 sudo apt install qt6-default qt6-base-dev qt6-base-private-dev qt6-tools-dev libqt6svg6 qt6-qtdeclarative
 ```
 Open the `ads.pro` file with QtCreator and start the build, that's it.
 You can run the demo project and test it yourself.
 ## Getting started / Example
 The following example shows the minimum code required to use the advanced Qt docking system.
 *MainWindow.h*
 ```cpp
 #include <QMainWindow>
 #include "DockManager.h"
 namespace Ui {
 class MainWindow;
 }
 class MainWindow : public QMainWindow
 {
    Q_OBJECT
 public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
 private:
    Ui::MainWindow *ui;
    // The main container for docking
    ads::CDockManager* m_DockManager;
 };
 ```
 *MainWindow.cpp*
 ```cpp
 #include "MainWindow.h"
 #include "ui_MainWindow.h"
 #include <QLabel>
 MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
 {
    ui->setupUi(this);
    // Create the dock manager after the ui is setup. Because the
    // parent parameter is a QMainWindow the dock manager registers
    // itself as the central widget as such the ui must be set up first.
    DockManager = new ads::CDockManager(this);
    // Create example content label - this can be any application specific
    // widget
    QLabel* l = new QLabel();
    l->setWordWrap(true);
    l->setAlignment(Qt::AlignTop | Qt::AlignLeft);
    l->setText("Lorem ipsum dolor sit amet, consectetuer adipiscing elit. ");
    // Create a dock widget with the title Label 1 and set the created label
    // as the dock widget content
    ads::CDockWidget* DockWidget = DockManager->createDockWidget("Label 1");
    DockWidget->setWidget(l);
    // Add the toggleViewAction of the dock widget to the menu to give
    // the user the possibility to show the dock widget if it has been closed
    ui->menuView->addAction(DockWidget->toggleViewAction());
    // Add the dock widget to the top dock widget area
    DockManager->addDockWidget(ads::TopDockWidgetArea, DockWidget);
 }
 MainWindow::~MainWindow()
 {
    delete ui;
 }
 ```

 [BlueQuartz Software](http://www.bluequartz.net/) has completely rewritten the old DREAM.3D version 6.5 application
 taking advantage of the Advanced Docking System to present a highly customizable user interface
 for DREAM3D-NX Version 7.

 ### [LabPlot](https://labplot.kde.org/)
 KDE LabPlot is the ultimate free, open source and cross-platform tool for scientists, engineers, and students who need to analyze and visualize data. With its intuitive interface and powerful features, you can create stunning plots and diagrams with ease. Whether you're working with CSV, FITS, or HDF5 data, KDE LabPlot makes it simple to import and analyze your data.
 The LabPlot project recently switched to the Qt Advanced Docking System for their user interface. This switch represents a significant improvement to the LabPlot software, allowing users to create and manage complex data visualization layouts with ease.

 ### [Scrutiny Debugger](https://scrutinydebugger.com/)
 Scrutiny is an [open source](https://github.com/scrutinydebugger/) non-intrusive, real-time debugger for embedded systems, built for fast introspection, memory access, and signal visualization—without stopping your application. It uses the Qt Advanced Docking System (ADS) to provide fully customizable dashboards for monitoring and control.
 Some of the highlights are:
 - **Debug without interfering** — Inspect C++ memory live without disrupting execution flow.
 - **HIL testing made easy** — Write to variables through the GUI or SDK to simulate conditions.
 - **Configure during production** — Access and tweak variables anytime via GUI or Python.
 - **Catch fast events** — Embedded graphs sample at task-level frequency, even with multithreading.
 - **Build your dashboard** — Use ADS to create and save custom layouts for your debug sessions.
 - **No JTAG needed** — Communicates over serial, CAN, or network interfaces.
 - **Compact C++11 library** — Lightweight and easy to integrate into your firmware.
 - **Live graphs and runtime values** — Visualize variables, RPVs, and aliases in real time.
 ADS powers Scrutiny’s flexible interface, letting users organize views and data panels to suit their workflow — ideal for real-time monitoring, testing, and debugging.

 ## Alternative Docking System Implementations
 If this Qt Advanced Docking System does not fit to your needs you may consider some of the alternative docking system solutions for Qt.
 ### KDDockWidgets
 This is an advanced docking framework for Qt from [KDAB](https://www.kdab.com/). The interesting thing is, that they separated GUI code from logic, so they can easily provide a QtQuick backend in the future.
 - [Blog post about KDDockWidgets](https://www.kdab.com/kddockwidgets/)

 **License:** dual-licensed, available under both commercial and GPL license.
 ### QtitanDocking
 This is a commercial component from [Developer Machines](https://www.devmachines.com/) for Qt Framework that allows to create a Microsoft like dockable user interface. They also offer a lot of other interesting and useful components for Qt. The library is available
 - [Product page](https://www.devmachines.com/qtitandocking-overview.html)
 **License:** Commercial license
 ### DockingPanes
 DockingPanes is a library for Qt Widgets that implements docking windows that have the look and feel of Visual Studio. It provides a simple API which allows an application to make use of docking windows with a few calls.

      not limited to compiled object code, generated documentation,
      and conversions to other media types.
      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).
      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.
      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to

      designated in writing by the copyright owner as "Not a Contribution."
      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.
   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.
   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.
   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:
      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and
      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and
      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and
      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.
      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.
   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.
   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.
   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.
   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

 # Advanced Docking System for Qt
 Qt Advanced Docking System lets you create customizable layouts using a full
 featured window docking system similar to what is found in many popular
 integrated development environments (IDEs) such as Visual Studio.
 [![Video Advanced Docking](https://raw.githubusercontent.com/githubuser0xFFFF/Qt-Advanced-Docking-System/master/doc/advanced-docking_video.png)](https://www.youtube.com/watch?v=7pdNfafg3Qc)
 Everything is implemented with standard Qt functionality without any
 platform specific code. Basic usage of QWidgets and QLayouts and using basic 
 styles as much as possible.
 ## Features
 ### Docking everywhere - with or without a central widget
 The Advanced Docking System works with or without a central widget.
 You can dock on every border of the main window or you can dock into each dock area - so you are
 free to dock almost everywhere.

 ### Docking inside floating windows
 There is no difference between the main window and a floating window. Docking
 into floating windows is supported.

 ### Grouped dragging
 When dragging the titlebar of a dock, all the tabs that are tabbed with it are 
 going to be dragged. So you can move complete groups of tabbed widgets into
 a floating widget or from one dock area to another one.

 ### Perspectives for fast switching of the complete main window layout
 A perspective defines the set and layout of dock windows in the main
 window. You can save the current layout of the dockmanager into a named
 perspective to make your own custom perspective. Later you can simply
 select a perspective from the perspective list to quickly switch the complete 
 main window layout.

 ### Opaque and non-opaque splitter resizing
 The advanced docking system uses standard QSplitters as resize separators and thus supports opaque and non-opaque resizing functionality of QSplitter. In some rare cases, for very complex widgets or on slow machines resizing via separator on the fly may cause flicking and glaring of rendered content inside a widget. The global dock manager flag `OpaqueSplitterResize` configures the resizing behaviour of the splitters. If this flag is set, then widgets are resized dynamically (opaquely) while interactively moving the splitters. 
 ![Opaque resizing](https://raw.githubusercontent.com/githubuser0xFFFF/Qt-Advanced-Docking-System/master/doc/opaque_resizing.gif)
 If this flag is cleared, the widget resizing is deferred until the mouse button is released - this is some kind of lazy resizing separator.

 ### Opaque and non-opaque undocking
 By default, opaque undocking is active. That means, as soon as you drag a dock widget or a dock area with a number of dock widgets it will be undocked and moved into a floating widget and then the floating widget will be dragged around. That means undocking will take place immediately. You can compare this with opaque splitter resizing. If the flag `OpaqueUndocking` is cleared, then non-opaque undocking is active. In this mode, undocking is more like a standard drag and drop operation. That means, the dragged dock widget or dock area is not undocked immediately. Instead, a drag preview widget is created and dragged around to indicate the future position of the dock widget or dock area. The actual dock operation is only executed when the mouse button is released. That makes it possible, to cancel an active drag operation with the escape key.
 The drag preview widget can be configured by a number of global dock manager flags:
 - `DragPreviewIsDynamic`: if this flag is enabled, the preview will be adjusted dynamically to the drop area
 - `DragPreviewShowsContentPixmap`: the created drag preview window shows a static copy of the content of the dock widget / dock are that is dragged
 - `DragPreviewHasWindowFrame`: this flag configures if the drag preview is frameless like a QRubberBand or looks like a real window
 The best way to test non-opaque undocking is to set the standard flags: `CDockManager::setConfigFlags(CDockManager::DefaultNonOpaqueConfig)`.
 ### Tab-menu for easy handling of many tabbed dock widgets
 Tabs are a good way to quickly switch between dockwidgets in a dockarea. However, if the number of dockwidgets in a dockarea is too large, this may affect the usability of the tab bar. To keep track in this situation, you can use the tab menu. The menu allows you to quickly select the dockwidget you want to activate from a drop down menu.

 ### Many different ways to detach dock widgets
 You can detach dock widgets and also dock areas in the following ways:
 - by dragging the dock widget tab or the dock area title bar
 - by double clicking the tab or title bar
 - by using the detach menu entry from the tab and title bar drop down menu
 ### Supports deletion of dynamically created dock widgets
 Normally clicking the close button of a dock widget will just hide the widget and the user can show it again using the toggleView() action of the dock widget. This is meant for user interfaces with a static amount of widgets. But the advanced docking system also supports dynamic dock widgets that will get deleted on close. If you set the dock widget flag `DockWidgetDeleteOnClose` for a certain dock widget, then it will be deleted as soon as you close this dock widget. This enables the implementation of user interfaces with dynamically created editors, like in word processing applications or source code development tools.
 ### Python PyQt5 Bindings
 ![Python Logo](https://raw.githubusercontent.com/githubuser0xFFFF/Qt-Advanced-Docking-System/master/doc/python_logo.png)
 The Advanced Docking System comes with a complete Python integration based on
 PyQt5 bindings. The package is available via [conda-forge](https://github.com/conda-forge/pyqtads-feedstock).
