[Interest] Adding icons to android action bar

[Nikos Chantziaras]

Is there a way to add action icons to the Android action bar?

I'm using QMainWindow and QMenuBar (so QWidgets, not QML). QMenuBar 
doesn't have any options for this. I tried QMainWindow::addToolBar(), 
but the tool bar appears below the action bar.

The action bar only has the three vertical "..." dots in it. Isn't there 
a way to populate it with anything more useful?
