Re: XGetInputFocus() does not work for GTK based applications

[Kala B <kalabalun yahoo co in>]

Hi Owen,
Thanks a lot for the immediate response. 
When I use the window id I get in the "focus" parameter of the following call
XGetInputFocus(disp,&focus,&revert);
as an input to xprop, I donot get any output.
that is, say I get the value 0x220001a in focus, 
xprop -id 0x220001a doesnot give me the properties. 
 
If your time permits, can you please explain to me the reason. Thanks.
 
Also, how do I get the window id of the window on focus ? I manually move the mouse to the window to the GTK 
window, but still, XGetInputFocus gives me a different id. 
 
How do I get the window id of the toplevel window?
 
 
Thanks a lot,
Kala

Nothing is "wrong" about the value you getting. GTK+ sets focus to
an immediate child of the toplevel rather than the toplevel itself.
