How to raise / focus a window?

[David Topper <topper virginia edu>]

I've got an app with several windows and one central "master" window 
which controls hiding / showing of the others.  Unfortunately, I can't 
seem to raise focus for a window.  I'm doing the following:

    if (GTK_IS_WIDGET(s_obj->perl_buf->window)) {
        gtk_widget_set_uposition(GTK_WIDGET(s_obj->perl_buf->window),
                            s_obj->perl_buf->x,
                            s_obj->perl_buf->y);
        gtk_widget_show(GTK_WIDGET(s_obj->perl_buf->window));
        gtk_window_activate_focus(s_obj->perl_buf->window);

But it doesn't seem to work.  I've also changed my WM from "focus 
follows mouse" to "click to focus" and neither works.  I'm running 
Slackware 9 and KDE.  

Anyone have an idea?

Thanks,

DT
