Implementation of this method is mandatory for a subclass of QPlatformCursor.
widgetCursor is a pointer to the QCursor that should be displayed.
widget is a pointer to the widget currently displayed at QCursor::pos(). Note that this may be 0 if the current position is not occupied by a displayed widget.

[virtual] void QPlatformCursor::pointerEvent(const QMouseEvent & event)
This method is called by Qt whenever a QMouseEvent is generated by the underlying pointer input. event is a reference to the QMouseEvent in question. A default do-nothing implementation is provided.
