Subject: [PATCH 2/3] Synthesize Enter/LeaveEvent for accepted QTabletEvent
|
|
|
|
When the tablet event is accepted, then Qt doesn't synthesize a mouse
|
|
event, it means that QApplicationPrivate::sendMouseEvent() will not be
|
|
called, and, therefore, enter/leave events will not be dispatched.
|
|
|
|
The patch looks a bit hackish. Ideally, the synthesize should happen
|
|
in QGuiApplicationPrivate::processTabletEvent(), which takes the decision
|
|
about synthesizing mouse events. But there is not enough information
|
|
on this level: neither qt_last_mouse_receiver nor the receiver widget
|
|
are known at this stage.
|
|
|
|
On Windows and other platforms where there is a parallel stream of
|
|
mouse events synthesized by the platform, we shouldn't generate these
|
|
events manually.
