-
-### 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)
-
-### 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 immediatelly. 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 immediatelly. 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.
-
-![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.
-
-### Python PyQt5 Bindings
-
-![Python Logo](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). The python integration has been contributed to this project
-by the following people:

-
-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. Because the parent parameter is a QMainWindow
-    // the dock manager registers itself as the central widget.
-    m_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 = new ads::CDockWidget("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
-    m_DockManager->addDockWidget(ads::TopDockWidgetArea, DockWidget);

-## Showcase
-
-### [Qt Creator IDE](https://www.qt.io/development-tools)
-
-From version 4.12 on, Qt Creator uses the Advanced Docking Framework for its
-Qt Quick Designer. This improves the usability when using multiple screens.
-
-![Qt Creator](doc/qtcreator.png)
-
-### [Qt Design Studio](https://www.qt.io/ui-design-tools)
-
-Taken from the [Qt Blog](https://www.qt.io/blog/qt-design-studio-1.5-beta-released):
-
-> The most obvious change in [Qt Design Studio 1.5](https://www.qt.io/blog/qt-design-studio-1.5-beta-released) is the integration of dock widgets using the Qt Advanced Docking System. This allows the user to fully customize the workspace and also to undock any view into its own top level window. This especially improves the usability when using multiple screens.
-
-![Qt Design Studio](doc/qt_design_studio.png)
-
-### [QmixElements](https://www.cetoni.com/products/qmixelements/)

+
+### 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
+
+![Python Logo](doc/python_logo.png)
+
+Thanks to the contribution of several users, the Advanced Docking System comes
+with a complete Python integration. Python bindings are available for **PyQt5** and
+**PySide6**.
+
+### PySide6
+
+A PySide6 ADS package is available via PyPi and can be installed on Windows,
+macOS, and Linux with:
+
+```bash
+pip install PySide6-QtAds
+```
+
+Sample code is available [here](https://github.com/mborgerson/Qt-Advanced-Docking-System/tree/pyside6/examples). To run the samples, you'll also need to install latest qtpy
+from source (pip install https://github.com/spyder-ide/qtpy/archive/refs/heads/master.zip).
+The PySide6 bindings were contributed by:
+
+- [mborgerson](https://github.com/mborgerson)
+
+For more information about the PySide6 bindings read [this](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/298) issue.
+
+### PyQt5
+
+A package is available via [conda-forge](https://github.com/conda-forge/pyqtads-feedstock).

+
+## Tested Compatible Environments
+
+### Supported Qt Versions
+
+The library supports **Qt5** and **Qt6**.
+
+### Windows
+
+Windows 10 [![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)
+
+The library was developed on and for Windows. It is used in a commercial Windows application and is therefore constantly tested.
+
+### macOS
+
+macOS [![Build Status](https://travis-ci.org/githubuser0xFFFF/Qt-Advanced-Docking-System.svg?branch=master)](https://travis-ci.org/githubuser0xFFFF/Qt-Advanced-Docking-System)
+
+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://travis-ci.org/githubuser0xFFFF/Qt-Advanced-Docking-System.svg?branch=master)](https://travis-ci.org/githubuser0xFFFF/Qt-Advanced-Docking-System)
+[![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 this 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 the following Linux distributions:
+
+- **Kubuntu 18.04 and 19.10**
+- **Ubuntu 18.04, 19.10 and 20.04**
+
+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).

+
+## Build
+
+The Linux build requires private header files. Make sure that they are installed:
+
+```bash
+sudo apt install qtbase5-private-dev
+```
+
+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.
+    m_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 = new ads::CDockWidget("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
+    m_DockManager->addDockWidget(ads::TopDockWidgetArea, DockWidget);
+}
+
+MainWindow::~MainWindow()
+{
+    delete ui;

 ### 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.

-
-If this flag is set, 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 immediatelly. You can compare this with opaque splitter resizing.

-If this flag is cleared (default), 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 immediatelly. 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.

+### `FloatingContainerForceNativeTitleBar` (Linux only)
+
+Since release 3.6 the library supports native title bars and window decorations
+for floating widgets on Linux (thanks to a user contribution).
+Native title bars and window decorations are supported by most Linux window
+managers, such as Compiz or Xfwm. Some window managers like KWin do not properly
+support this feature. Native floating widgets look better because of the native
+styling and the support all window manager features like snapping to window
+borders or maximizing. The library tries to detect the window manager during
+runtime and activates native window decorations if possible:
+
+![FloatingContainerForceNativeTitleBar true](cfg_flag_FloatingContainerForceNativeTitleBar_true.png)
+
+If you would like to overwrite this autodetection, then you can  activate this
+flag to force native window titlebars. You can overwrite autodetection and this
+flag, if you set the environment variable `ADS_UseNativeTitle` to 0 or 1.
+
+### `FloatingContainerForceQWidgetTitleBar` (Linux only)
+
+If your window manager (i.e. KWin) does not properly support native floating
+windows, the docking library falls back to QWidget based floating widget
+title bars.
+
+![FloatingContainerForceNativeTitleBar false](cfg_flag_FloatingContainerForceNativeTitleBar_false.png)

+to force QWidget based title bars. You can overwrite autodetection and this
+flag, if you set the environment variable `ADS_UseNativeTitle` to 0 or 1.
+
+### `MiddleMouseButtonClosesTab`
+
+If the flag is set, the user can use the mouse middle button to close the tab
+under the mouse. So you do not need to exactly hit the tab close button to
+close tab. Just click with the middle mouse button on a tab like this is
+possible in various web browsers.
+
+![MiddleMouseButtonClosesTab true](cfg_flag_MiddleMouseButtonClosesTab.gif)
+
+## Auto-Hide Configuration Flags
+
+### Auto Hide Dock Widgets
+
+The Advanced Docking System supports "Auto-Hide" functionality for **all**
+dock containers. 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.
+
+Enabling this feature adds a button with a pin icon to each dock area.
+
+![DockAreaHasAutoHideButton true](cfg_flag_DockAreaHasAutoHideButton.png)
+
+By clicking this button, the current dock widget (or the complete area - depending on the
+configuration flags) will be pinned to a certain border. The border is choosen
+depending on the location of the dock area. If you click the pin button while
+holding down the **Ctrl** key, the whole dock area will be pinned to a certain
+border.
+
+### Pinning Auto-Hide Widgets to a certain border
+
+If you would like to pin a dock widget or a dock area to a certain border,
+then you can right-click into the dock widget tab or into the dock area title bar
+to show the context menu. Then you can select the location via the **Pin to** menu:
+
+![Pin to](AutoHide_PinTo.png)
+
+### Show / Hide Auto-Hide Widgets via Mouse Over
+
+Normally Auto-Hide widgets are shown by clicking the Auto-Hide tab and hidden by
+clicking the Auto-Hide tab again or by clicking into any other dock widget in
+the same container. If the Auto-Hide config flag `AutoHideShowOnMouseOver` is set,
+the Auto-Hide widget is shown, if the user hovers over the Auto-Hide tab and is
+collapsed if the mouse cursor leaves the Auto-Hide widget. Showing and hiding
+by mouse click still works if this feature is enabled.
+
+### Adding Auto Hide Widgets
+
+Adding an auto hide widget is similar to adding a dock widget, simply call
+`dockManager->addAutoHideDockWidget()`.
+
+```c++
+CDockManager::setAutoHideConfigFlags(CDockManager::DefaultAutoHideConfig);
+d->DockManager = new CDockManager(this);
+CDockWidget* TableDockWidget = new CDockWidget("Table 1");
+DockManager->addAutoHideDockWidget(SideBarLeft, TableDockWidget);
+```
+
+See `autohide` example or the demo application to learn how it works.
+
+### Setting Auto-Hide Flags
+
+The Advanced Docking System has a number of global configuration flags to
+configure the Auto-Hide functionality. You should set the Auto-Hide flags before
+creating the dock manager instance. That means, you should set the Auto-Hide
+flags after setting the configuration flags.
+
+```c++
+CDockManager::setConfigFlag(CDockManager::FocusHighlighting, true);
+CDockManager::setAutoHideConfigFlags(CDockManager::DefaultAutoHideConfig);
+CDockManager::setAutoHideConfigFlag(CDockManager::AutoHideShowOnMouseOver, true);
+...
+d->DockManager = new CDockManager(this);
+```
+
+If you set the Auto-Hide flags, you can set individual flags using the
+function `CDockManager::setAutoHideConfigFlag` or you can set all flags using
+the function `CDockManager::setAutoHideConfigFlags`. Instead of settings all
+flags individually, it is better to pick a predefined set of configuration
+flags and then modify individual flags. The following predefined
+configurations are available
+
+- `DefaultAutoHideConfig` - default auto hide config
+
+Pick one of those predefined configurations and then modify the following
+configurations flags to adjust the docking system to your needs.
+
+### `AutoHideFeatureEnabled`
+
+Enables / disables the Auto-Hide functionality. Only if this flag is enabled,
+the other Auto-Hide flags will be evaluated.
+
+### `DockAreaHasAutoHideButton`
+
+If this flag is set (default), then each dock area has a pin button in the title 
+bar to toggle Auto-Hide state.
+
+![DockAreaHasAutoHideButton true](cfg_flag_DockAreaHasAutoHideButton.png)
+
+### `AutoHideButtonTogglesArea`
+
+If set, the the pin button in the dock area title bar toggles the complete area.
+If not set (default), then the pin button toggles the current active tab / dock
+widget and pressing the **Ctrl** key while clicking the pin button toggles the
+complete ara.
+
+### `AutoHideButtonCheckable`
+
+Normally the pin button in the dock area title bar is not checkable. If this
+flag is set, then the button is checkable. That means, if button is checked,
+the dock widget is pinned.
+
+### `AutoHideSideBarsIconOnly`
+
+Normally the Auto-Hide tabs show the icon and title of the dock widget:
+
+![AutoHideSideBarsIconOnly false](cfg_flag_AutoHideSideBarsIconOnly_false.png)
+
+You can set this flag, if you would like to have only icons in the Auto-Hide
+tabs instead of icon and dock widget title. If this is set, the Auto-Hide tab
+needs less space. The tooltip of each tab still shows the dock widget title.
+
+![AutoHideSideBarsIconOnly true](cfg_flag_AutoHideSideBarsIconOnly_true.png)
+
+### `AutoHideShowOnMouseOver`
+
+Normally Auto-Hide widgets are shown by clicking the Auto-Hide tab and
+hidden by clicking the Auto-Hide tab again or by clicking into any other
+dock widget in the same container. If this flag is set, the Auto-Hide widget
+is shown, if the user hovers over the Auto-Hide tab or if the users moves the
+mouse outside of the Auto-Hide widget. Showing and hiding my mouse click still
+works if this feature is enabled.
+
+## DockWidget Feature Flags
+
+### `DockWidgetClosable`
+
+If set, the dock widget will have a close button.
+
+### `DockWidgetMovable`
+
+If a dock widget is movable, then it and can be moved to a new position in the
+current dock container. Disable this flag to prevent moving of a dock widget
+via mouse.
+
+### `DockWidgetFloatable`
+
+If set, a dock widget can be dragged into a floating window.
+
+### `DockWidgetDeleteOnClose`
+
+Deletes the dock widget and its content when it is closed.
+
+### `CustomCloseHandling`
+
+Clicking the close button will not close the dock widget but emits the
+`closeRequested()` signal instead. This allows the application to implement
+a custom close handling.
+
+### `DockWidgetFocusable`
+
+If this is enabled, a dock widget can get focus highlighting.
+
+### `DockWidgetForceCloseWithArea`
+
+A dock widget will be closed when the dock area hosting it is closed. If the
+`DockWidgetDeleteOnClose` feature is enabled for a dock widget, then it will
+be deleted, if the user clicks the close button of this dock widget. If the
+user clicks the close button of the dock area that contains this widget,
+then only the visibility of the dock widget is toggled. If this feature flag
+is set, the closing the dock area also closes the dock widget. That means, if
+the dock widget feature `DockWidgetDeleteOnClose` is set for the dock widgets
+in a dock area, then all dock widgets will be deleted if the dock area is closed.
+
+### `NoTab`
+
+A dock widget tab will never be shown if this flag is set.
+
+### `DeleteContentOnClose`
+
+Deletes only the contained widget on close, keeping the dock widget intact and
+in place. Attempts to rebuild the contents widget on show if there is a widget
+factory set. See [issue #365](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/pull/365) for more details.
+
+## Central Widget
+
+The Advanced Docking System has been developed to overcome the limitations of
+the native Qt docking system with its central widget concept. This was the
+reason that until version 3.6 of the library, there was no support for such
+thing like a central widget. Thanks to the contribution of a user the library
+now supports a central widget.
+
+In the Advanced Docking System a central widget is a docking widget that is
+neither closable nor movable or floatable. A central widget has no title bar
+and so it is not possible for the user to hide, close or drag the central
+widget. If there is a central widget, then also the distribution of the sizes
+for the dock widgets around the central widget is different:
+
+- **no central widget (default)** - on resizing the available space is
+distributed to all dock widgets - the size of all dock widgets
+shrinks or grows
+- **with central widget** - on resizing only the central widget is resized - the
+dock widgets around the central widget keep their size (see the animation below)
+
+![Central Widget](central_widget.gif)
+
+To set a central widget, you just need to pass your central dock widget
+to the dock manager `setCentralWidget` function:
+
+```c++
+auto* CentralDockArea = DockManager->setCentralWidget(CentralDockWidget);
+```
+
+See the `centralwidget` example to learn how it works.
+
+> ##### Note
+> The central widget needs to be the first dock widget that is added to the
+> dock manager. The function does not work and returns a `nullptr` if there
+> are already other dock widgets registered. So `setCentralWidget` should be
+> the first function that you call when adding dock widgets.
+
+## Empty Dock Area
+
+Some applications require a fixed DockArea that is always visible, even if it
+does not contain any DockWidgets. I.e. the DockArea is in this case a kind
+of central widget that is always visible (see this
+[issue](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/199)).
+
+Since version 3.7.1 the advanced docking system supports this feature. The
+`emptydockarea` example shows how this can be implemented with the library. You
+just need to create a dock widget and set the feature flag `CDockWidget::NoTab`.
+This permanently hides the tab widget of this area and removes it from the tab
+menu. For this special dock widget you should also disable all other features
+(movable, closable and floatable) to prevent closing and moving of this widget.
+If you use the `CDockManager::setCentralWidget` function like in the example
+code below, then you don't need to disable these features because this is done
+in the `setCentralWidget` function.
+
+```c++
+QLabel* label = new QLabel();
+label->setText("This is a DockArea which is always visible, even if it does not contain any DockWidgets.");
+label->setAlignment(Qt::AlignCenter);
+CDockWidget* CentralDockWidget = new CDockWidget("CentralWidget");
+CentralDockWidget->setWidget(label);
+CentralDockWidget->setFeature(ads::CDockWidget::NoTab, true);// set the flag before adding the widget to dock manager
+auto* CentralDockArea = DockManager->setCentralWidget(CentralDockWidget);
+```
+
+## Custom Close Handling
+
+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.
+
+When an entire area is closed, the default behavior is to hide the dock widgets it contains regardless of the `DockWidgetDeleteOnClose` flag except if there is only one dock widget. In this special case, the `DockWidgetDeleteOnClose` flag is followed. This behavior can be changed by setting the `DockWidgetForceCloseWithArea` flag to all the dock widgets that needs to be closed with their area.
