The Escape Key

[Richard Heck]

I've discovered a problem with my fix for bug 3461, at changeset 17920. 
The problem there was that the dialog needed to be reset when it was 
closed by hitting the cancel button. What I've realized is that the same 
problem arises with the escape button: Hitting escape does not trigger 
slotClose(), and it does not trigger a closeEvent(), either. It's easy 
enough to deal with this by connecting rejected() to something 
appropriate. The first question is to what it should be connected, and 
whether it should be connected to slotClose(). The second question is 
whether this is a more general problem. Should ESC be connected to 
slotClose() elsewhere? if so, should this be done in some more general 
manner?
