Hi all,

i have a problem with manually sending key events and shortcuts on Qt

In our application, we have a QAction with a F5 shortcut in a toolbar. When
i press the toolbutton everything works fine. When i press the F5 key on my
keyboard too.
But when i press a pushbutton, where the connected slot generate a
QKeyEvent and send this event via QApplication::sendEvent nothing will
With Qt 5.4.1 it works, but with 5.5.0 not.

I have attached a small example app, which describes my problem.

Is this problem already known? Have you a patch or work around for me?

Thanks in advance.
