In an earlier project we've used the following code, which seems
to work :

#include <gdk/gdkx.h>

void
window_iconify (GdkWindow *window)
{
  XWMHints *xwmh;
  GdkWindowPrivate *private;

  private = (GdkWindowPrivate*) window;
  xwmh = XGetWMHints (private->xdisplay, private->xwindow);
  xwmh->initial_state = IconicState;
  xwmh->flags |= StateHint;
  XSetWMHints (private->xdisplay, private->xwindow, xwmh);
} 

void
window_deiconify (GdkWindow *window)
{
  GdkWindowPrivate *private;

  private = (GdkWindowPrivate*) window;
  XMapRaised (private->xdisplay, private->xwindow);
} 

gboolean
window_is_iconified (GdkWindow *window)
{
  XWindowAttributes xattr;
  GdkWindowPrivate *private;

  private = (GdkWindowPrivate*) window;

  xattr.map_state = IsUnmapped;
  XGetWindowAttributes(private->xdisplay, private->xwindow, &xattr);
  return (xattr.map_state == IsUnmapped); 
}

Then you can do something like this :

  if (!GTK_WIDGET_VISIBLE (dialog))
    gtk_widget_show (dialog);
  else if (window_is_iconized (dialog->window))
    window_deiconify (dialog->window);
  else
    gdk_window_raise (dialog->window);

bye,
