I have a very simple libglade application.  I used glade-2.0.1 to

It defines
two signal handlers.   A  realize and destroy signal for the 
GtkWindow. when i use the following as my main applicaion the realize 
signal handler is not
called.

I expect to run the program see my window pop up and see hello 
printed at the terminal.
I get no Gtk Warnings or Errors instead.  I think its important to 
have this realize signal
handler called because I want to initialize my application here.

any ideas?  Am i misuing the api? is this a bug in libglade?

I've tested this with the lastest unstable release of libglade and a 
fairly recent cvs version and
noticed the same behavoir.


Your window is just realized before glade_xml_signal_autoconnect() 
call. Possible solutions:
1. (the nice one) Test your main window widget with 
GTK_WIDGET_REALIZED() macro.
2. (the worse and untested) Set "Visible" flag ("Common" tab in 
"Properties" notebook) to FALSE, get a pointer to your window (with 
call like 'glade_xml_get_widget(xml, "window1")') and call 
gtk_widget_show_all() on it before gtk_main().

I have a work around for my problem that i'd like to share. basically it 
involves
creating the window manually and only reading in the part of the glade file
that i want to embed into my application.

int main( int argc, char **argv )
{
  App app;
  GtkWidget *hero_win;
  GtkWidget *glade_widget_hook;
                                                                               
 
  gtk_init( &argc, &argv );
                                                                               
 
  /* load the interface */
  app.xml = glade_xml_new( "gui.glade", "vbox1", NULL );
  if( app.xml == NULL ){
    g_error( "Failed to initialize glade_xml file" );
    return 1;
  }
  /* connect the signals in the interface */
  glade_xml_signal_autoconnect_with_data( app.xml, &app );
                                                                               
 
  glade_widget_hook = glade_xml_get_widget( app.xml, "vbox1" );
                                                                               
 
  hero_win = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title( GTK_WINDOW( hero_win ), "HERO" );
  gtk_container_add( GTK_CONTAINER( hero_win ), glade_widget_hook );
                                                                               
 
  g_signal_connect ((gpointer) hero_win, "destroy",
                    G_CALLBACK (on_hero_win_destroy),
                    &app );
  g_signal_connect ((gpointer) hero_win, "realize",
                    G_CALLBACK (on_hero_win_realize),
                    &app );
  gtk_widget_show( hero_win );
                                                                               
 
  /* start the event loop */
  gtk_main();
