Hi,
I'm writing a small app that should automatically deiconify a
window and warp the pointer to its location for text input. However
everytime i try and grab the pointer it fails ! If i manually
deiconify thru my window manager then the grab succeeds. This leads
me to believe that the deiconifying functions in gtk/gdk are not ICCM
compliant and don't set the WM_STATE properly, or am i doing something
wrong in my code ? I have appended my short example with all superfuolous
code taken out. The window should popup and popdown every 2 seconds in
this test example and grab the pointer when it is deiconized.
Can anyone help please ?
Thanx
Dave
