[Interest] Qt 5: how to disable single-click activation in QAbstractItemView's?

[R. Reucher]

Hi!

I successfully managed to "port" all of my major applications to Qt 5, but I'm 
facing some issues... the one that bothers me the most at the moment is the 
fact that now every style seems to activate items on a *single* mouse-click, 
in Qt 4 this only happens with certains styles (i. e. imported ones like 
Oxygen from KDE 4).

Is there some easy way to revive the "old" (Qt 4) behavior? I actually find it 
very annoying...

Thanks in advance, René
