-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.
+## New and Noteworthy
 
-This work is based on and inspired by the 
-[Advanced Docking System for Qt](https://github.com/mfreiholz/Qt-Advanced-Docking-System) 
-from Manuel Freiholz. I did an almost complete rewrite of his code to improve
-code quality, readibility and to fix all issues from the issue tracker 
-of his docking system project.
+The [release 3.8](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/latest)
+adds the following features:
+
+- option to close tabs with the middle mouse button
+- `DeleteContentOnClose` flag for dynamic deletion and creation of dock widget
+  content
+
+The [release 3.7](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/tag/3.7.2)
+adds the following features:
+
+- support for **Qt6.**
+- support for [empty dock area](doc/user-guide.md#empty-dock-area)
+
+The [release 3.6](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/tag/3.6.3)
+adds some nice new features:
+
+- support for [central widget](doc/user-guide.md#central-widget) concept
+
+![Central Widget](doc/central_widget.gif)
+
+- support for [native floating widgets](doc/user-guide.md#floatingcontainerforcenativetitlebar-linux-only) on Linux

+![FloatingContainerForceNativeTitleBar true](doc/cfg_flag_FloatingContainerForceNativeTitleBar_true.png)
+
+Both features are contributions from ADS users. Read the [documentation](doc/user-guide.md)
+to learn more about both new features.
+
+The [release 3.5](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/tag/3.5.0)
+adds the new [focus highlighting](doc/user-guide.md#focushighlighting) feature.
+This optional feature enables highlighting of the focused dock widget like you

 ### 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.

@@ -129,8 +178,26 @@ You can detach dock widgets and also dock areas in the following ways:
 
 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.

-The application can be compiled for Linux and has been developed and tested with **Kubuntu 18.04** and **Kubuntu 19.10**.
+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).

 ### 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.

@@ -107,3 +92,10 @@ You can detach dock widgets and also dock areas in the following ways:
 ### 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.

+## Configuration Flags
+
+The Advanced Docking System has a number of global configuration options to
+configure the design and the functionality of the docking system. Eachs
+configuration will be explained in detail in the following sections.
+
+### Setting Configuration Flags
+
+You must set the configuration flags before creating the dock manager
+instance otherwise the manager will not be created correctly and will
+crash upon being created. That means, setting the configurations flags
+is the first thing you must do, if you use the library.
+
+```c++
+CDockManager::setConfigFlags(CDockManager::DefaultOpaqueConfig);
+CDockManager::setConfigFlag(CDockManager::RetainTabSizeWhenCloseButtonHidden, true);
+...
+d->DockManager = new CDockManager(this);
+```
+
+If you set the configurations flags, you can set individual flags using the
+function `CDockManager::setConfigFlag` or you can set all flags using
+the function `CDockManager::setConfigFlags`. Instead of settings all
+flags individualy, it is better to pick a predefined set of configuration
+flags and then modify individual flags. The following predefined
+configurations are avilable
+
+- `DefaultNonOpaqueConfig` - uses non opaque splitter resizing and non opaque docking
+- `DefaultOpaqueConfig` - uses opaque splitter resizing and opaque docking
+
+Pick one of those predefined configurations and then modify the following
+configurations flags to adjust the docking system to your needs.
+
+### `ActiveTabHasCloseButton`
+
+If this flag is set (default configuration), the active tab in a tab area has
+a close button.
+
+![ActiveTabHasCloseButton true](cfg_flag_ActiveTabHasCloseButton_true.png)
+
+If this flag is cleared, the active tab has no close button. You can combine
+this with the flag `DockAreaCloseButtonClosesTab` to use the close button
+of the dock are to close the single tabs.
+
+![ActiveTabHasCloseButton true](cfg_flag_ActiveTabHasCloseButton_false.png)
+
+### `DockAreaHasCloseButton`
+
+If the flag is set (default configuration) each dock area has a close button.
+
+![DockAreaHasCloseButton true](cfg_flag_DockAreaHasCloseButton_true.png)
+
+If this flag is cleared, dock areas do not have a close button.
+
+![DockAreaHasCloseButton true](cfg_flag_DockAreaHasCloseButton_false.png)
+
+### `DockAreaCloseButtonClosesTab`
+
+If the flag is set, the dock area close button closes the active tab,
+if not set, it closes the complete dock area (default).
+
+### `OpaqueSplitterResize`
+
+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. This global dock manager flag configures the resizing behaviour of the splitters. If this flag is set, then widgets are resized dynamically (opaquely) while interactively moving the splitters. If you select the predefined configuration `DefaultOpaqueConfig`, then this is the configured behaviour.
+
+![Opaque resizing](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. If you select the predefined
+configuration `DefaultNonOpaqueConfig`, then this is the configured behaviour.
+
+![Non-opaque resizing](non_opaque_resizing.gif)
+
+### `XmlAutoFormattingEnabled`
+
+If enabled, the XML writer automatically adds line-breaks and indentation to
+empty sections between elements (ignorable whitespace). This is used, when
+the current state or perspective is saved. It is disabled by default.
+
+### `XmlCompressionEnabled`
+
+If enabled, the XML output will be compressed and is not human readable anymore.
+This ie enabled by default to minimize the size of the saved data.
+
+### `TabCloseButtonIsToolButton`
+
+If enabled the tab close buttons will be `QToolButtons` instead of `QPushButtons` - 
+disabled by default. Normally the default configuration should be ok but if your
+application requires `QToolButtons` instead of `QPushButtons` for styling reasons
+or for any other reasons, then you can enable this flag.
+
+### `AllTabsHaveCloseButton`
+
+If this flag is set, then all tabs that are closable show a close button. The
+advantage of this setting is that the size of the tabs does not change and the
+user can immediately close each tab. The disadvantage is that all tabs take up
+more space.
+
+![AllTabsHaveCloseButton true](cfg_flag_AllTabsHaveCloseButton_true.png)
+
+If this flas is cleared, then only the active tab has a close button (default)
+and therefore the tabs need less space.
+
+![AllTabsHaveCloseButton false](cfg_flag_ActiveTabHasCloseButton_true.png)
+
+### `RetainTabSizeWhenCloseButtonHidden`
+
+If this flag is set, the space for the close button is reserved even if the
+close button is not visible. This flag is disabled by default. If this flag
+is disabled, the tab size dynamically changes if the close button is
+visible / hidden in a tab. If this flag is enabled, the tab size always remains
+constant, that means, if enabled, the tabs need more space.
+
+![AllTabsHaveCloseButton false](cfg_flag_RetainTabSizeWhenCloseButtonHidden_true.png)
+
+### `OpaqueUndocking`
+
+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.
+
+![OpaqueUndocking true](opaque_undocking.gif)
+
+If you would like to test opaque undocking, you should set the pedefined config
+flags `CDockManager::DefaultOpaqueConfig`.
+
+```c++
+CDockManager::setConfigFlags(CDockManager::DefaultOpaqueConfig);
+```
+
+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.
+
+![OpaqueUndocking true](non_opaque_undocking.gif)
+
+The drag preview widget can be configured by a number of global dock manager flags:
+
+- `DragPreviewIsDynamic`
+- `DragPreviewShowsContentPixmap`
+- `DragPreviewHasWindowFrame`
+
+Non-opaque undocking is enabled by default. If you would like to enable it
+explicitely, you can do this by setting the predefined configuration flags
+`CDockManager::DefaultNonOpaqueConfig`.
+
+```c++
+CDockManager::setConfigFlags(CDockManager::DefaultNonOpaqueConfig);
+```
+
+### `DragPreviewIsDynamic`
+
+If non-opaque undocking is enabled, this flag defines the behavior of the drag 
+preview window. If this flag is enabled, then it will give the user the
+impression, that the floating drag preview is dynamically adjusted to the drop
+area. In order to give the perfect impression, you should disable the flags
+`DragPreviewShowsContentPixmap` and `DragPreviewHasWindowFrame`.
+
+```c++
+CDockManager::setConfigFlag(CDockManager::DragPreviewIsDynamic, true);
+CDockManager::setConfigFlag(CDockManager::DragPreviewShowsContentPixmap, false);
+CDockManager::setConfigFlag(CDockManager::DragPreviewHasWindowFrame, false);
+```
+
+![DragPreviewIsDynamic true](dynamic_drag_preview.gif)
+
+### `DragPreviewShowsContentPixmap`
+
+If non-opaque undocking is enabled, the created drag preview window shows a 
+copy of the content of the dock widget / dock are that is dragged, if this
+flag is enabled (default).
+
+![DragPreviewShowsContentPixmap true](cfg_flag_DragPreviewShowsContentPixmap_true.png)
+
+If this flag is disabled, the drag preview is only a transparent `QRubberBand`
+like window without any content.
+
+![DragPreviewShowsContentPixmap true](cfg_flag_DragPreviewShowsContentPixmap_false.png)
+
+### `DragPreviewHasWindowFrame`
+
+If non-opaque undocking is enabled, then this flag configures if the drag 
+preview is frameless (default) or looks like a real window. If it is enabled,
+then the drag preview is a transparent window with a system window frame.
+
+![DragPreviewHasWindowFrame true](cfg_flag_DragPreviewHasWindowFrame_true.png)
+
+### `AlwaysShowTabs`
+
+If this option is enabled, the tab of a dock widget is always displayed - even
+if it is the only visible dock widget in a floating widget. In the image below
+on the left side, the flag is disabled (default) and on the right side it is
+enabled.
+
+![AlwaysShowTabs false true](cfg_flag_AlwaysShowTabs_false_true.png)
+
+### `DockAreaHasUndockButton`
+
+If the flag is set (default) each dock area has an undock button (right
+image). If the flag is cleared, a dock area has no undock button (left image)
+
+![DockAreaHasUndockButton false true](cfg_flag_DockAreaHasUndockButton_false_true.png)
+
+### `DockAreaHasTabsMenuButton`
+
+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. This flag shows / hides the tabs menu button
+in the dock area title bar. On the left side, the tabs menu button flag
+is cleared.
+
+![DockAreaHasTabsMenuButton false true](cfg_flag_DockAreaHasTabsMenuButton_false_true.png)
+
+### `DockAreaHideDisabledButtons`
+
+If certain flags of a dock widget are disabled, like `DockWidgetClosable` or
+`DockWidgetFloatable`, then the corresponding dock area buttons like close
+button or detach button are disabled (greyed out). This is the default
+setting.
+
+![DockAreaHideDisabledButtons false](cfg_flag_DockAreaHideDisabledButtons_false.png)
+
+If the flag is set, disabled dock area buttons will not appear on the toolbar at
+all - they are hidden.
+
+![DockAreaHideDisabledButtons true](cfg_flag_DockAreaHideDisabledButtons_true.png)
+
+### `DockAreaDynamicTabsMenuButtonVisibility`
+
+If this flag is cleared, the the tabs menu button is always visible. This is
+the default setting. If the flag is set, the tabs menu button will be shown
+only when it is required - that means, if the tabs are elided.
+
+![DockAreaDynamicTabsMenuButtonVisibility false](cfg_flag_DockAreaDynamicTabsMenuButtonVisibility_true_visible.png)
+
+If the tabs are not elided, the tabs menu button is hidden.
+
+![DockAreaDynamicTabsMenuButtonVisibility false](cfg_flag_DockAreaDynamicTabsMenuButtonVisibility_true_hidden.png)
+
+### `FloatingContainerHasWidgetTitle`
+
+If set (default), the floating widget window title reflects the title of the
+current dock widget.
+
+![FloatingContainerHasWidgetTitle true](cfg_flag_FloatingContainerHasWidgetTitle_true.png)
+
+otherwise it displays application name as window title.
+
+![FloatingContainerHasWidgetTitle false](cfg_flag_FloatingContainerHasWidgetTitle_false.png)
+
+### `FloatingContainerHasWidgetIcon`
+
+If set, the floating widget icon reflects the icon of the current dock widget
+
+![FloatingContainerHasWidgetIcon true](cfg_flag_FloatingContainerHasWidgetIcon_true.png)
+
+otherwise (default setting) it displays application icon.
+
+![FloatingContainerHasWidgetIcon false](cfg_flag_FloatingContainerHasWidgetIcon_false.png)
+
+### `HideSingleCentralWidgetTitleBar`
+
+If there is only one single visible dock widget in the main dock container (the dock manager)
+and if this flag is set, then the titlebar of this dock widget will be hidden.
+This only makes sense for non draggable and non floatable dock widgets and enables
+the creation of some kind of "central" static widget. Because the titlebar is
+hidden, it is not possible to drag out the central widget to make it floating
+or to close it via the close button.
+
+![HideSingleCentralWidgetTitleBar true](cfg_flag_HideSingleCentralWidgetTitleBar_true.png)
+
+The Advanced Docking System is meant for applications without a static central
+widget and normally does not know anything about a central static widget.
+Therefore this flag is disabled by default and a central single dock widget
+still has a titlebar to drag it out of the main window.
+
+![HideSingleCentralWidgetTitleBar false](cfg_flag_HideSingleCentralWidgetTitleBar_false.png)
+
+### `FocusHighlighting`
+
+If this is enabled, the docking system is able to highlight the tab and the
+components of a dock area with a different style (i.e. a different color).
+This option is disabled by default and needs to be enabled explicitely
+because it adds some overhead. The dock manager needs to react on focus
+changes and dock widget dragging to highlight the right dock widget. You should
+enable it only, if you really need it for your application.
+
+If the feature is enabled, you can also connect to the new dock manager
+signal `focusedDockWidgetChanged(CDockWidget* old, CDockWidget* now)` to
+react on focus changes and to prepare the content of the focused dock
+widget.
+
+You can click into the tab, the titlebar or the content of a dock widget
+to focus it.
+
+![FocusHighlighting](cfg_flag_FocusHighlighting.gif)
+
+For the focused dock widget and dock widget tab, the property `focused` will
+be set to true and you can use this property to style the focused dock
+widget differently. The picture above uses the following styling:
+
+```css
+/* Color the tab with the nhighlight color */
+ads--CDockWidgetTab[focused="true"]
+{
+    background: palette(highlight);
+    border-color: palette(highlight);
+}
+
+/* Use a different colored close button icon to match the test color */
+ads--CDockWidgetTab[focused="true"] > #tabCloseButton
+{
+	qproperty-icon: url(:/ads/images/close-button-focused.svg)
+}
+
+/* Make a hovered focused close button a little bit lighter */
+ads--CDockWidgetTab[focused="true"] > #tabCloseButton:hover
+{
+	background: rgba(255, 255, 255, 48);
+}
+
+/* Make a pressed focused close button even more lighter */
+ads--CDockWidgetTab[focused="true"] > #tabCloseButton:pressed
+{
+	background: rgba(255, 255, 255, 92);
+}
+
+/* Use a different color for the tab label */
+ads--CDockWidgetTab[focused="true"] QLabel
+{
+    color: palette(light);
+}
+
+/* Paint a nice solid line for the whole title bar to create the illusion
+   of an active tab */
+ads--CDockAreaWidget[focused="true"] ads--CDockAreaTitleBar
+{
+	background: transparent;
+	border-bottom: 2px solid palette(highlight);
+	padding-bottom: 0px;
+}
+```
+
+If you have a content widget that does not support focussing for some reason
+(like `QVTKOpenGLStereoWidget` from the [VTK library](https://github.com/Kitware/VTK)),
+then you can manually switch the focus by reacting on mouse events. The 
+following code shows, how to install en event filter on the `QVTKOpenGLStereoWidget`
+to properly switch the focus on `QEvent::MouseButtonPress`:
+
+```c++
+static ads::CDockWidget* createVTK2DWindow(QMenu* ViewMenu, QObject* EventFilter)
+{
+    QVTKOpenGLStereoWidget* qvtkOpenGLStereoWidget = new QVTKOpenGLStereoWidget;
+    ads::CDockWidget* DockWidget = new ads::CDockWidget("2D Window");
+    DockWidget->setWidget(qvtkOpenGLStereoWidget);
+    qvtkOpenGLStereoWidget->installEventFilter(EventFilter);
+    qvtkOpenGLStereoWidget->setProperty("DockWidget", QVariant::fromValue(DockWidget));
+    return DockWidget;
+}
+```
+
+Now we can use the event filter function to react on mouse events and then
+use the dock manager function `setDockWidgetFocused()` to switch the focus:
+
+```c++
+bool CMainWindow::eventFilter(QObject *watched, QEvent *event)
+{
+    if (event->type() == QEvent::MouseButtonPress)
+    {
+        QVTKOpenGLStereoWidget* vtkWidget =  qobject_cast<QVTKOpenGLStereoWidget*>(watched);
+        auto vDockWidget = vtkWidget->property("DockWidget");
+        ads::CDockWidget* DockWidget = nullptr;
+        if (vDockWidget.isValid())
+        {
+            DockWidget = qvariant_cast<ads::CDockWidget*>(vDockWidget);
+        }
+
+        if (DockWidget)
+        {
+            d->DockManager->setDockWidgetFocused(DockWidget);
+        }
+    }
+    return false;
+}
+```
+
+### `EqualSplitOnInsertion`
+
+This flag configures how the space is distributed if a new dock widget is
+inserted into an existing dock area. The flag is disabled by default. If 3 
+dock widgets are inserted with the following code
+
+```c++
+d->DockManager->addDockWidget(ads::RightDockWidgetArea, DockWidget, EditorArea);
+```
+
+then this is the result, if the flag is disabled:
+
+![EqualSplitOnInsertion false](cfg_flag_EqualSplitOnInsertion_false.png)
+
+If the flag is enabled, then the space is equally distributed to all widgets 
+in a  splitter:
+
+![EqualSplitOnInsertion true](cfg_flag_EqualSplitOnInsertion_true.png)
+
+
+### `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)
+
+If you would like to overwrite autodetection, then you can activate this flag
+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)
+
+## 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. If the `OpaqueUndocking` configuration flag is set, then dock widgets
+are immediately undocked into floating widgets. That means, moving is only
+possible in this case, if the dock widget is also floatable (feature flag
+`DockWidgetFloatable` is set).
+
+### `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.
+
+## Styling
+
+The Advanced Docking System supports styling via [Qt Style Sheets](https://doc.qt.io/qt-5/stylesheet.html). All components like splitters, tabs, buttons, titlebar and
+icons are styleable this way.
+
+### Disabling the Internal Style Sheet
+
+The dock manager uses an internal stylesheet to style its components. That
+means, the style that you see in the demo application comes from the
+internal stylesheets that you will find in `src/stylesheets` folder. If you want
+to disable this internal stylesheet because your application uses its own,
+just call the function for settings the stylesheet with an empty string.
+
+```c++
+DockManager->setStyleSheet("");
+```
