Touch panel keyboard in GNUstep app

[Andreas Höschler]

Hi all,

I am just trying to add a touch panel keyboard feature to some GNUstep app, 
meaning that I have added a bunch of NSButtons with titles "A", "B", "C",... to 
the GUI of my app. My plan is to generate and send some key-event whenever a 
user clicks (actually presses with his finger on a touch screen) on one of the 
on-screen keyboard buttons. 

However, for this to work I need to make sure that the keyboard buttons never 
get first responder but that e.g. an NSTextField in the GUI (first responder 
before clicking on a key button) stays first responder and receives the 
programmatically generated key-event. 

I have run

        [button setRefusesFirstResponder:YES];

on the keyboard buttons but this did not do the trick. The NSTextField that is 
first responder before clicking on one of the key board buttons resigns first 
responder before the action of the button is executed. :-(

Any idea how to correctly set this up?

Thanks a lot in advance!!

Best, 

   Andreas
