/* wxQt specific notes:
*
* Remember to implement the Qt object getters on all subclasses:
* - GetHandle() returns the Qt object
* - QtGetScrollBarsContainer() returns the widget where scrollbars are placed
* For example, for wxFrame, GetHandle() is the QMainWindow,
* QtGetScrollBarsContainer() is the central widget and QtGetContainer() is a widget
* in a layout inside the central widget that also contains the scrollbars.
* Return 0 from QtGetScrollBarsContainer() to disable SetScrollBar() and friends
* for wxWindow subclasses.
*
*
* Event handling is achieved by using the template class wxQtEventForwarder
* found in winevent_qt.(h|cpp) to send all Qt events here to QtHandleXXXEvent()
* methods. All these methods receive the Qt event and the handler. This is
* done because events of the containers (the scrolled part of the window) are
* sent to the same wxWindow instance, that must be able to differenciate them
* as some events need different handling (paintEvent) depending on that.
* We pass the QWidget pointer to all event handlers for consistency.
