Key Equivalent on button

[Andreas Höschler]

Hello all,

I implemented a panel (NSPanel) with a textfield and the buttons Cancel 
and OK. I would like the ok button to be fired when the user hits 
return in the text field. According to my understanding of the OPENSTEP 
spec one should get this behaviour with

   [okButton setKeyEquivalent:@"\r"];

This at least works under MacOSX. On GNUstep this does not do anything. 
While googling I found a hint regarding the modifier mask. I therefore 
also tried

   [okButton setKeyEquivalent:@"\r"];
   [okButton setKeyEquivalentModifierMask:NSControlKeyMask];

but this didn't chane anything. I found no key sequence (Return, 
Ctrl-Return, Command-Return,...) that would cause the ok button to 
perform its action. What am I missing? Any workaround (seems to be a 
GNUstep bug) or idea how thi smight be fixed?

Thanks,

 Andreas
