you shouldn't post questions about general usage of GTK+
to gtk-devel-list. This list's purpose is to discuss the
development of GTK+.

the code GLADE generates is really ugly and I can only
strongly suggest you try to learn how to code GTK+ by
hand. Since you haven't posted all your code, I can only
guess what is causing your problem. I'd say you create
the dialog and forget to show all the widgets in it. Or
you call gtk_widget_hide_all() on it at some point 
(which is a rarely useful function, but I saw that you 
used it in your code). Later on you try to show the
window:

> gtk_widget_show_now((GtkWidget *) dialogCommand);

this command will only show the window, but not all
widgets you've put inside. Try to replace that call
by gtk_widget_show_all() or make sure that all widgets
are shown and only the dialog window gets hidden and
shown when needed.
