gtk_window_show/hide

["Nob Kato" <nobkato mbox kyoto-inet or jp>]

Hello.

I want to show/hide gtk-window from other thread in same process.
so I tried to write a program as follows.

1. from other process (e.g.terminal-program "kill -n 40(or 41) pid")
      my window show/hide successfully.

2. form other thread in same process: call raise (40) or raise (41)
      my window does not  hide.
      but "SHOW" or "HIDE" are displayed.(printf)

please help me.

thanks
Nob

#define SIG_SHOW 40
#define SIG_SHOW 41

main ()
{
  ...
  main_window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  ...
  sigaction (SIG_SHOW, &act, 0);
  sigaction (SIG_HIDE, &act, 0);
  ...
  gtk_main();
}

void *signal_handler ( int sig)
{
  switch (sig) {
  case SIG_SHOW:
    gtk_window_show (main_window);
    printf ("SHOW\n");
    break;
  case SIG_HIDE:
    gtk_window_hide (main_window);
    printf ("HIDE\n");
    break;
  }
  return NULL;
