Here are some tips for implementing custom title bars:
\list
- \i Mouse events that are not explicitly handled by the title bar widget
+ \o Mouse events that are not explicitly handled by the title bar widget
must be ignored by calling QMouseEvent::ignore(). These events then
propagate to the QDockWidget parent, which handles them in the usual
manner, moving when the title bar is dragged, docking and undocking
when it is double-clicked, etc.
- \i When DockWidgetVerticalTitleBar is set on QDockWidget, the title
+ \o When DockWidgetVerticalTitleBar is set on QDockWidget, the title
bar widget is repositioned accordingly. In resizeEvent(), the title
bar should check what orientation it should assume:

+ \o The title bar widget must have a valid QWidget::sizeHint() and
QWidget::minimumSizeHint(). These functions should take into account
the current orientation of the title bar.

+ \o It is not possible to remove a title bar from a dock widget. However,
+ a similar effect can be achieved by setting a default constructed
+ QWidget as the title bar widget.

+ Using qobject_cast() as shown above, the title bar widget has full access
to its parent QDockWidget. Hence it can perform such operations as docking
and hiding in response to user actions.
