Re: GTK Modal dialog

[Miroslav Rajcic <rajcic@xxxxxxxxxxx>]

My dialog is GtkDialog, not the window :-(

Unfortunately, Linux version (gcc 3.3.3, Fedora Core 2 with gtk 2.4.7) 
works kind of OK,
but Win32 version does not work OK (Visual C++ 6.0 with SP6, gtk 2.4.9).

On Linux my dialog does not fall through to the bottow of the window 
z-order when I click on its parent window.
On Windows, this is exactly what happens (mybe it is a bug in 
gtk_window_set_keep_above API ?).

But even on Linux, I don't have a proper modal feeling, my dialog stays 
on top, but I can achieve loosing main window (fall through on the 
bottom) while dialog stays on top and focused. Really strange, smells 
like bug to me.

To clear any misunderstanding my code looks like this:

   dialog1 = gtk_dialog_new ();
   gtk_window_set_modal (GTK_WINDOW (dialog1), TRUE);
   gtk_window_set_skip_pager_hint (GTK_WINDOW (dialog1), TRUE);
   gtk_window_set_skip_taskbar_hint (GTK_WINDOW (dialog1), TRUE);
   gtk_window_set_type_hint (GTK_WINDOW (dialog1), 
GDK_WINDOW_TYPE_HINT_DIALOG);
   gtk_window_set_transient_for(GTK_WINDOW (dialog1), 
GTK_WINDOW(window1));   //set parent
   gtk_window_set_keep_above(GTK_WINDOW (dialog1), TRUE);
   gtk_window_set_position(GTK_WINDOW (dialog1), 
GTK_WIN_POS_CENTER_ON_PARENT);

   g_signal_connect (dialog1, "destroy", GTK_SIGNAL_FUNC 
(gtk_main_quit), NULL);

   //show dialog
   gtk_widget_show(dialog1);
   gtk_grab_add(dialog1);    //disable everything except this dialog

   //block in modal state
   //gtk_main();
   GMainLoop *loop = g_main_new (FALSE);
   GDK_THREADS_LEAVE ();
   g_main_run (loop);  // Loop will block here
   GDK_THREADS_ENTER ();
  
   //cleanup
   gtk_grab_remove(dialog1);
   gtk_widget_destroy(dialog1);

Anyway, I am stuck with this, any help is welcome.

I've read that gnome_dialog_run() does exactly what I need, but I must 
use GTK only.
It seems really strange that GTK does not have this already implemented.

Best regards,
