Dialog problems

[Thomas Rast <t rast iname com>]

Hi everybody

a few days ago, I programmed a little test with libgnome/libgnomeui (I have
attached the full sources). *Very* easy to do menus, toolbars, ... !!

But the "about" dialog didn't work. I have a callback to create one:

static void
about_cb (GtkWidget *button, gpointer data)
{
	GtkWidget *about_dialog;
	const gchar *authors [] = {
		"Thomas Rast <t.rast@iname.com>",
		NULL
	};
	
	about_dialog = gnome_about_new ("Menu Test", "0.1", "(c) 2000 Thomas Rast",
		authors, "Just a test", NULL);
	
	gnome_dialog_set_parent (GNOME_DIALOG (about_dialog), GTK_WINDOW (app));
	
	gtk_widget_show (about_dialog);
}

It's like in the tutorial, except the strings. I had a look at the
gmenu-sources (well, i've got very old gnome-core/libs, shame on me :),
it's the same too.

The menus are defined with

GnomeUIInfo helpmenu [] = {
	GNOMEUIINFO_MENU_ABOUT_ITEM (about_cb, NULL),
	GNOMEUIINFO_END
};

GnomeUIInfo menubar [] = {
	GNOMEUIINFO_MENU_HELP_TREE (helpmenu),
	GNOMEUIINFO_END
};

void
create_menu (void)
{
	gnome_app_create_menus (GNOME_APP (app), menubar);
}

I call create_menu from main ().

Now I compiled, runned and clicked help -> about, and then there is nothing
happening. file -> exit (see full source) worked.

Thanks in advance for your help.
