Well,
there's prolly several ways of doing it, but smth. along the following
lines should work:
GladeXML *gxml = glade_xml_new (GLADE_FILE, "dialog1", NULL);
GtkWidget *dialog = glade_xml_get_widget(gxml, "dialog1");
g_assert(dialog);
GtkResponseType result;
// register function to be executed in intervals
g_timeout_add(1000, update_pbar, dialog);
result = gtk_dialog_run(GTK_DIALOG(dialog));
if (result == GTK_RESPONSE_OK)
{
}
gtk_widget_destroy(dialog);
dialog = NULL;
then you need the timeout function:
gboolean
update_pbar (gpointer dialog)
{
// stop executing and unregister this function if dialog has
// been set to NULL
if (!dialog) return 0;
// if dialog has not been displayed yet, don't bother updating
// the progress bar
if (!GTK_WIDGET_VISIBLE(GTK_WIDGET(dialog))) return 1;
...
do whatever needs to be done to update the progressbar here
return 1;
}
HTH,
Karl.
