in your gtk app you should request X11 to send your Focus information 
XSelectInput(GDK_DISPLAY(), GDK_ROOT_WINDOW(), FocusChangeMask);

install handler
gdk_window_add_filter(gdk_get_default_root_window (), (GdkFilterFunc)event_filter, data);


static GdkFilterReturn
event_filter(GdkXEvent *xevent, GdkEvent *event, Panel *p)
{
    XEvent *ev = (XEvent *) xevent;
    Window win;
    int type;
    
    if (ev->type == FocusIn || ev->type == FocusOut) {
        XGetInputFocus(GDK_DISPLAY(), &win, &type);
        //do some thing else
    } 
}

I think this code will help you :-)
