 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.

 ## New and Noteworthy
 
-The [release 3.8](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/tag/3.8.0)
+### Release 4.5
+
+#### Tabs at Bottom
+
+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.
+
+If the flag is set, tabs will be shown at the bottom instead of in the title bar.
+
+![TabsAtBottom true](doc/cfg_flag_TabsAtBottom_true.png)
+
+### Release 4.1
+
+Release [4.1](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/releases/latest) significantly improves the Auto-Hide functionality and also brings improvements
+for Drag and Drop of dock widgets into dock area tabs. These are the highlights of the new version:
+
+#### Drag & Drop to Auto-Hide
+
+Now you can easily drag any dock widget or any floating widget to the
+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
+drop overlays will be shown to indicate the drop area for auto-hide widgets:
+
+![Auo-Hide drag to Sidebar](doc/AutoHide_Drag_to_Sidebar.gif)
+
+Of course, this also works with dock areas:
+
+![Auo-Hide drag Dock Area](doc/AutoHide_Drag_DockArea.gif)
+
+If you drag a dock widget or dock area into a sidebar, then you even have
+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.
+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
+be inserted before the **Table 0** Auto-Hide tab and the **Image Viewer 2**
+is appende behind the last tab:
+
+![Auo-Hide tab insert order](doc/AutoHide_Tab_Insert_Order.gif)
+
+#### Auto-Hide Tab Insertion Order
+
+It is also possible to drag Auto-Hide tabs to a new auto-hide position.
+That means, you can drag them to a different border or sidebar:
+
+![Auto-Hide change sidebar](doc/AutoHide_Change_Sidebar.gif)
+
+#### Auto-Hide Tab Sorting
+
+You can drag Auto-Hide tabs to a new position in the current sidebar
+to sort them:
+
+![Auo-Hide sort tabs](doc/AutoHide_Sort_Tabs.gif)
+
+#### Auto-Hide Drag to Float / Dock
+
+But that is not all. You can also simply move Auto-Hide tabs to another
+floating widget or dock them via drag and drop:
+
+![Auo-Hide drag to float or dock](doc/AutoHide_Drag_to_Float_or_Dock.gif)
+
+#### Auto-Hide Context Menu
+
+All Auto-Hide tabs now have a context menu, that provides all the functionality
+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
+sidebar:
+
+![Auo-Hide context menu](doc/AutoHide_Context_Menu.png)
+
+#### Dock Area Tab Insert Order
+
+And last but not least the new version also improves the docking of widgets
+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
+(appending):
+
+![Dock area tab insert order](doc/DockArea_Tab_Insertion_Order.gif)

-### Opaque and non-opaque undocking
+### Cancelable docking process
 
-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.
+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
 
-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.
@@ -171,19 +293,91 @@ 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.

+### 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
+

 ### 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.

 ### 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 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 chosen
+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.
+
+### Drag & Drop to Auto-Hide
+
+You can easily drag any dock widget or any floating widget to the
+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
+drop overlays will be shown to indicate the drop area for auto-hide widgets:
+
+![Auo-Hide drag to Sidebar](AutoHide_Drag_to_Sidebar.gif)
+
+Of course, this also works with dock areas:
+
+![Auo-Hide drag Dock Area](AutoHide_Drag_DockArea.gif)
+
+If you drag a dock widget or dock area into a sidebar, then you even have
+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.
+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
+be inserted before the **Table 0** Auto-Hide tab and the **Image Viewer 2**
+is appended behind the last tab:
+
+![Auo-Hide tab insert order](AutoHide_Tab_Insert_Order.gif)
+
+### Auto-Hide Tab Insertion Order
+
+It is also possible to drag Auto-Hide tabs to a new auto-hide position.
+That means, you can drag them to a different border or sidebar:
+
+![Auto-Hide change sidebar](AutoHide_Change_Sidebar.gif)
+
+### Auto-Hide Tab Sorting
+
+You can drag Auto-Hide tabs to a new position in the current sidebar
+to sort them:
+
+![Auo-Hide sort tabs](AutoHide_Sort_Tabs.gif)
+
+### Auto-Hide Drag to Float / Dock
+
+But that is not all. You can also simply move Auto-Hide tabs to another
+floating widget or dock them via drag and drop:
+
+![Auo-Hide drag to float or dock](AutoHide_Drag_to_Float_or_Dock.gif)
+
+### Auto-Hide Context Menu
+
+All Auto-Hide tabs now have a context menu, that provides all the functionality
+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
+sidebar:
+
+![Auo-Hide context menu](AutoHide_Context_Menu.png)
+
+### 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.
+
+## Auto-Hide Configuration Flags
+
+### 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.
+
+### `AutoHideCloseButtonCollapsesDock`
+
+Some users don't understand the distinction between closing an auto hide dock and
+collapsing an auto hide dock. This may lead to situations where they press the
+close button (losing the side tab widget) instead of simply clicking outside
+the auto hide dock (collapsing the dock).
+
+![AutoHideCloseButtonCollapsesDock false](cfg_flag_AutoHideCloseButtonCollapsesDock_false.gif)
+
+If `AutoHideCloseButtonCollapsesDock` option is active, the
+close button in an auto hide widget collapses the auto hide widget instead of
+closing it.
+
+![AutoHideCloseButtonCollapsesDock true](cfg_flag_AutoHideCloseButtonCollapsesDock_true.gif)
+
+If you enable the `AutoHideHasMinimizeButton` flag, you should disable this
+flag our you will have two buttons with minimize functionality.
+
+### `AutoHideHasCloseButton`
+
+If this flag is set (default), then each auto hide widget has a close button:
+
+![AutoHideHasCloseButton](cfg_flag_AutoHideHasCloseButton.png)
+
+The functionality of the close button (close or minimize) is configured by the
+`AutoHideCloseButtonCollapsesDock` flag.
+
+### `AutoHideHasMinimizeButton`
+
+If this flag is set (disabled by default), then each auto hide widget has a minimize button.
+
+![AutoHideHasMinimizeButton](cfg_flag_AutoHideHasMinimizeButton.png)
+
+### `AutoHideOpenOnDragHover`
+
+If this flag is set (disabled by default), then holding a dragging cursor hover an auto-hide collapsed dock's tab will open said dock:
+
+![AutoHideOpenOnDragHover](cfg_flag_AutoHideOpenOnDragHover.gif)
+
+Said dock must be set to accept drops to hide when cursor leaves its scope. See `AutoHideDragNDropExample` for more details.
+
+### `AutoHideCloseOnOutsideMouseClick`
+
+If this flag is set (default), the auto hide dock container will collapse if the
+user clicks outside of the container. If not set, the auto hide container can be
+closed only via click on auto hide sidebar tab.

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.
 
+## Globally Lock Docking Features
+
+It is possible to globally lock features of all dock widgets to "freeze" the
+current workspace layout. That means, you can now lock your workspace
+to avoid accidentally dragging a docked view. When locking wasn't possible,
+users had to manually dock it back to the desired place after each accidental
+undock.
+
+You can use a combination of the following feature flags to define which features
+shall get locked:
+
+- `CDockWidget::DockWidgetClosable`
+- `CDockWidget::DockWidgetMovable`
+- `CDockWidget::DockWidgetFloatable`
+- `CDockWidget::DockWidgetPinable`
+
+To clear the locked features, you can use `CDockWidget::NoDockWidgetFeatures`
+The following code shows how to lock and unlock all dock widget features
+globally.
+
+```c++
+DockManager->lockDockWidgetFeaturesGlobally();
+DockManager->lockDockWidgetFeaturesGlobally(CDockWidget::NoDockWidgetFeatures);
+```
+
+## Dock Widget Size / Minimum Size Handling
+
+There are several `CDockWidget` mode enums to control how a `CDockWidget` is
+resized and how the docking system handles the minimum size of a dockwidget.
+
+The first one is the `eInsertMode` enum:
+
+```c++
+enum eInsertMode
+{
+    AutoScrollArea,
+    ForceScrollArea,
+    ForceNoScrollArea
+};
+```
+
+The InsertMode defines how the widget is inserted into the dock widget, when you 
+call the `CDockWidget::setWidget` method:
+
+```c++
+DockWidget->setWidget(widget, CDockWidget::AutoScrollArea);
+```
+
+The content of a dock widget should be resizable do a very small size to
+prevent the dock widget from blocking the resizing. To ensure, that a
+dock widget can be resized very well, it is better to insert the content
+widget into a scroll area or to provide a widget that is already a scroll
+area or that contains a scroll area (such as an `QAbstractItemView`)
+If the InsertMode is `AutoScrollArea`, the DockWidget tries to automatically
+detect how to insert the given widget. If the widget is derived from
+`QScrollArea` (i.e. an `QAbstractItemView`), then the widget is inserted
+directly. If the given widget is not a scroll area, the widget will be
+inserted into a scroll area.
+
+To force insertion into a scroll area, you can also provide the InsertMode
+`ForceScrollArea`. In this case a scroll area will also be created for content
+widgets that are derived from `QScrollArea` To prevent insertion into a scroll
+area, you can provide the InsertMode `ForceNoScrollArea`. In this case, the
+content widget is always inserted directly.
+
+A second enum, the `eMinimumSizeHintMode` defines, which value will be returned
+from the `CDockWidget::minimumSizeHint()` function:
+
+```c++
+enum eMinimumSizeHintMode
+{
+    MinimumSizeHintFromDockWidget,
+    MinimumSizeHintFromContent,
+    MinimumSizeHintFromDockWidgetMinimumSize,
+    MinimumSizeHintFromContentMinimumSize,
+};
+```
+
+To ensure, that a dock widget does not block resizing, the dock widget
+reimplements `minimumSizeHint()` function to return a very small minimum
+size hint. If you would like to adhere the `minimumSizeHint()` from the
+content widget, then set the `minimumSizeHintMode()` to
+`MinimumSizeHintFromContent`. If you would like to use the `minimumSize()`
+value of the content widget or the dock widget, then you can use the
+`MinimumSizeHintFromDockWidgetMinimumSize` or
+`MinimumSizeHintFromContentMinimumSize` modes.

+## Using ADS on Linux
+
+### Supported Distributions
+
+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
+
+### Requirements 
+
+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).

+### Manjaro xfce 25.0.1 and Xubuntu 24.04.2 issues
+
+There is a known focus stealing issue with the xfce4 compositor reported in issue [#734]. This issue
+can be solved by enabling the setting **Activate focus stealing prevention**. `Settings > Window Manager Tweaks` has a tab called `Focus`.
+
+Selecting `Activate focus stealing prevention` and `Do nothing` for `When a window raises itself`, seems to mitigate the issue. Deselecting `Enable display compositing` on the `Compositor` tab, also works.

+## OpenGl + ADS
+
+If you would like to use OpenGL widgets with ADS such as `GLWidget`, QML or `QWebEngineView`, then you need
+to set `QApplication::setAttribute(Qt::AA_ShareOpenGLContexts)` before creating your application and your
+widgets (see issue [#732])
+
+```c++
+int main(int argc, char *argv[])
