+Description: fix notification of QDockWidget when it gets undocked
+ Before the patch the notification was emitted only when the docker
+ was attached to the panel or changed a position on it.
+ .
+ It looks like the old behavior was documented in a unittest,
+ so this patch might actually be a "behavior change".
+ .

+Subject: [PATCH] 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.
