Hi Greg,
I am in fact trying to catch both keyboard button down and button up events.
So my code goes like this
GrSelectEvents(win1, GR_EVENT_MASK_KEY_DOWN |
GR_EVENT_MASK_KEY_UP);
I am able to catch keyboard button down events but the keyboard button up
events are simply not registering. Also I am linking application onto
server. So I dont have a Xserver running seperately. I just run the appln
from the console.
Thanks,
Ritesh.
