In cocoa, saying that a panel accepts key events, will make it receive
key events, but also show it as the active window on screen. The former
we dont really have to care about, since Qt will take care of forwarding
events to the popup for us anyway, even when they target another window.
So the only reason to actually let a panel become key window, is when
we want it to become active. And for popups, we only want this to happend
for Tool windows.
