999 * destroyed during the call to gtk_dialog_run(), gtk_dialog_run() returns
1000 * #GTK_RESPONSE_NONE. Otherwise, it returns the response ID from the
1001 * ::response signal emission.
1003 * Before entering the recursive main loop, gtk_dialog_run() calls
1004 * gtk_widget_show() on the dialog for you. Note that you still
1005 * need to show any children of the dialog yourself.
1007 * During gtk_dialog_run(), the default behavior of #GtkWidget::delete-event
1008 * is disabled; if the dialog receives ::delete_event, it will not be
1009 * destroyed as windows usually are, and gtk_dialog_run() will return
1010 * #GTK_RESPONSE_DELETE_EVENT. Also, during gtk_dialog_run() the dialog
1011 * will be modal. You can force gtk_dialog_run() to return at any time by
1012 * calling gtk_dialog_response() to emit the ::response signal. Destroying
1013 * the dialog during gtk_dialog_run() is a very bad idea, because your
1014 * post-run code won't know whether the dialog was destroyed or not.
1016 * After gtk_dialog_run() returns, you are responsible for hiding or
1017 * destroying the dialog if you wish to do so.
1019 * Typical usage of this function might be:
1021 * gint result = gtk_dialog_run (GTK_DIALOG (dialog));

1028 * do_nothing_since_dialog_was_cancelled ();
1031 * gtk_widget_destroy (dialog);
1034 * Note that even though the recursive main loop gives the effect of a
1035 * modal dialog (it prevents the user from interacting with other
1036 * windows in the same window group while the dialog is run), callbacks
1037 * such as timeouts, IO channel watches, DND drops, etc, <emphasis>will</emphasis>
1038 * be triggered during a gtk_dialog_run() call.
1040 * Return value: response ID
