The original drawing mechanism was generating lots of QWarning messages when running samples (e.g. htlbox, caret, etc.) and in some cases was not actually completely drawing every element of the sample. The issue was that the QPicture was being shared incorrectly between wxWindow and wxClientDC and attempts to start painting, update, etc. were generating console warnings. Closes https://github.com/wxWidgets/wxWidgets/pull/1152

/* 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.
