Shawn Rutledge f931e5e72d add cross-platform tablet->mouse event synth; enable on Android It's urgent to fix the issue that on Android, it became impossible to interact with any widget or MouseArea which handles only mouse events but not tablet events, using the stylus, because stylus events are sent only as QTabletEvents. Before 5.6 (change `01d78ba86a`) they were sent as touch events, and mouse events were synthesized from those. Whereas on other platforms, every QTabletEvent is followed by a synthesized QMouseEvent. This fix proceeds in the direction that event synthesis should be done in cross-platform code so that platform plugins don't have to repeat it, following the same pattern as for touch->mouse synthesis. Just as in that case, the application can disable it, and the platform plugin can also report that it's unnecessary for Qt to do the synthesis because the platform already does. So QTBUG-51618 is fixed, but QTBUG-47007 requires us to remove the tablet->mouse synthesis from all platform plugins, because the plugin does not know whether the tablet event was accepted or not, so it does not have enough information to decide whether to synthesize a mouse event. Synthesis has been unconditional until now, which contradicts what the documentation says: the mouse event should be sent only if the tablet event is NOT accepted. We can now gradually make this promise come true. [ChangeLog][QtCore][Tablet support] A synthetic mouse event will no longer be sent after every QTabletEvent, only after those which are not accepted (as documented).

README

Qt is supplied with a number of example applications that have been
written to provide developers with examples of the Qt API in use,
highlight good programming practice, and showcase features found in each of
Qt's core technologies.


Documentation for examples can be found in the Examples section
of the Qt documentation.
