Re: [Java-gnome-developer] Glade with multiple gtk windows or dialog

[alcapcom <alc...@gm...>]

Thank's for the reply Andrew,

Before posting i have already try to handle these event with the
lifeCycleListener, but that did not work, I "re" try with your
recommendation but I obtains the same errors.

Here the code:

Dialog Class:
...
public Dialog dialog = (Dialog) glade.getWidget("dialog_display_manager");
...
public void defaultContrutor() {
 dialog.addListener(new LifeCycleListener() {
   public void lifeCycleEvent(LifeCycleEvent event) {
    }
    public boolean lifeCycleQuery(LifeCycleEvent event) {
        if (event.isOfType(LifeCycleEvent.Type.DESTROY)
            || event.isOfType(LifeCycleEvent.Type.DELETE)) {
            dialog.hide();
         }
         return true;
     }
 });
}
...

Window Class (Main):
...
public Window window = (Window) glade.getWidget("window_main");
...
public void defaultConstructor() {
 window.addListener(new LifeCycleListener(){
   public void lifeCycleEvent(LifeCycleEvent event) {
    }
    public boolean lifeCycleQuery(LifeCycleEvent event) {
        if (event.isOfType(LifeCycleEvent.Type.DESTROY)
               || event.isOfType(LifeCycleEvent.Type.DELETE)) {
               Gtk.mainQuit();
         }
         return false;
     }
 });
}
...
public static void on_button_add_display_clicked() {
   glade.getWidget("dialog_display_manager").show();
}
...

ps: I use the last version provided on Fedora Core 5 (libgtk 2.8.5,
