Updated cmake build for demo to use quick and quickwidgets

* fix side bar state being incorrect during restore

* isVisible is invalid during restore state

* Make visibleTabCount function consistent with hasVisibleTabs. Add a bit of documentation.

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 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.

+## 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.
+
+### `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.
