Yes this looks good, thanks!
I did not even think about this...

Slots are in games often very unhandy. For example I have a hack in kpoker 
which I'd like to get rid of:
slotExchangeCard1();
slotExchangeCard2();
slotExchangeCard3();
slotExchangeCard4();
slotExchangeCard5();
They all simply call setHeld(n); , where n is the number of the slot... All of 
this in a single keyPressEvent() would be nicer.
For a dynamic number of cards (in this example) the problem gets worse. Ok 
dynamic number of cards may be quite unrealistic... so speaking about real 
time strategy games - dynamic number of unit groups or something like this. 
Then I had to use a lot of sender() hacks which makes it very difficult to 
use the same function without the KAction signals.

I have not yet tried to add another KActionCollection object, but it looks 
like the correct solution. I'll port some existing games in a few weeks (once 
I passed my exams).
