Raising window and setting keyboard focus

[Chris Kurecka]

Hi,

I'm trying to write a program using Xlib that will move another window
to the foreground and give it keyboard focus.  I tried using the
following calls:

Window raise;
/* assign raise to appropriate window */
XRaiseWindow(dpy, raise);
XSetInputFocus(dpy, raise, RevertToNone, CurrentTime);

This raises the window to the foreground but does not give it input
focus, which still goes to the terminal that launched my program.

I also tried:
int did_it_work = XGrabKeyboard(dpy, raise, false, GrabModeAsync,
GrabModeAsync, CurrentTime);

No errors are returned.  Is this not working because I didn't create
the window I'm trying to change the focus to, or is it something else?
 I've tried it in both KDE and GNOME, so I don't think it's window
manager dependent.  Is there any way to do what I'm seeking, without
using Qt/GTK calls?

Thanks a lot!
