Hi Bin,
  Thanks for the reply. I am new to GTK and could you please explain it in
more details?

Thanks,
Kay

 Dear All,

 embed the former xlib window into a GTK top-level window. I wrote a
 small test program as below but it doesn't work. Does anyone have any
 idea about how this is gonna work?

 #include string.h
 #include X11/Xlib.h
 #include X11/keysym.h
 #include gtk/gtk.h
 #include gdk/gdkx.h
 #include stdlib.h
 #include stdio.h
 #include sys/types.h

 void destroy (GtkWidget *widget, gpointer *data)
 {
 gtk_main_quit ();
 }



 int main(int argc, char* argv[])
 {
 Display* display = XOpenDisplay(NULL);
 int screen = DefaultScreen(display);
 int width = DisplayWidth(display, screen)/6;
 int height = DisplayHeight(display, screen)/6;
 GtkWidget *gtkWin;
 XEvent e;
 pid_t pid;
 Bool child = FALSE;
 int timer = 0;

 gtk_init (argc, argv);

 gtkWin = gtk_window_new(GTK_WINDOW_TOPLEVEL);

 gtk_signal_connect(GTK_OBJECT(gtkWin),
 destroy,GTK_SIGNAL_FUNC(destroy),NULL);

 gtk_widget_realize(gtkWin);

 Window win = XCreateSimpleWindow(display, RootWindow(display,
 screen),
 0, 0, width, height, 3, BlackPixel(display, screen),
 WhitePixel(display, screen));
 XStoreName(display, win, hello);
 GC gc = XCreateGC(display, win, 0, NULL);

I don't think this way can work. To embed a X window in Gtk window, I
think you must handle the redraw event of the X window and manually
copy the drawables to the Gtk+ window.

Hi Kevin,
  I have looked into Gtkplug, but the problem is that Gtkplug has to be the
toplevel window, which drives the question back to how to make a Gtkplug as
a parent window of an X window. I don't quite get your code, is it
reparenting a gtk window to a gdk now?

Thanks and Regards,
Ke

Look into GtkPlug or something like this... where windowid is the Xid of
a window. And window is a gtk_window object

if (windowid != 0) {

window_container = gdk_window_foreign_new(windowid);
if (GTK_WIDGET_MAPPED(window))
gtk_widget_unmap(window);

gdk_window_reparent(window-window, window_container, 0, 0);

}

Kevin
