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

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

Hello List,

I have a problem on using glade with several Windows/dialog in a Gtk
application.
When I try to open Dialog/Window after having already close it, I
obtain the following errors.

(java-gnome: 6316): GLib-GObject-CRITICAL **: g_object_ref: assertion
"G_IS_OBJECT (object)" failed
(java-gnome: 6316): GLib-GObject-WARNING **: authority with invalid
(NULL) class to point
(java-gnome: 6316): GLib-GObject-CRITICAL **: g_signal_emit_valist:
assertion "G_TYPE_CHECK_INSTANCE (authority)" failed
(java-gnome: 6316): GLib-GObject-CRITICAL **: g_object_notify:
assertion "G_IS_OBJECT (object)" failed
(java-gnome: 6316): GLib-GObject-CRITICAL **: g_object_unref:
assertion "G_IS_OBJECT (object)" failed

I have try to intercepted delete_event and event_destroy without success.
I really do not see how not intercepted the signal to overload him
with for example Window.hide (), or some thing like that.

Did somebody already have this kind of problem?

In advance, Thanks
Alphonse

All you should have to trap is LifeCycleEvent.Type.DELETE in
lifeCylceQuery() of the LifeCycleListener.

If you call the Window's hide() method, then the object will still be
live. When doing so, however, you have to return true to tell GTK that
you've handled it so that it does not continue to propagate the signal.
[This is important because the default handler for delete-event is to in
turn emit destroy-event with the default result that the Window is
destroyed]

Did you return true?

If you post your code you'll probably make it easier for people to help
you.

P.S. I just noticed that the JavaDoc for LifeCycleListener is mush, so
I'm fixing it.

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.

> If you post your code you'll probably make it easier for people to help

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,
libglade 2.12,glib 0.2.3).

Are you sure that defaultContrutor is being called? (You didn't paste
any code that calls it and it does have an unusual name). Try adding
printlns for both calls to defaultContrutor and lifeCycleQuery to
check what's actually happening.

Shame on me!
It was well a problem of contructor not called.

Thanks.
