I think this is my problem.
So I made a new dialog:

       GladeXML *gxml = glade_xml_new (GLADE_FILE, "dialog1", NULL);
       GtkWidget *dialog = glade_xml_get_widget(gxml, "dialog1");
       GtkResponseType result;

       result = gtk_dialog_run(GTK_DIALOG(dialog));

       if (result == GTK_RESPONSE_OK)
       {
       }
       gtk_widget_destroy(dialog);

The window (dialog) now appears, but I want a "progress window", with
a progressbar and a label for the description. But how can I make
somthing while the dialog is visible so that I can show the progress
to the user?

Thanks for the help.
