如何释放物体？ [Java-GNOME]

Question

how do i release objects in java-gnome library? first, i give an example...

package gui;

import org.gnome.gdk.Event;
import org.gnome.gtk.Button;
import org.gnome.gtk.Widget;
import org.gnome.gtk.Window;

public class A extends Window implements Window.DeleteEvent
{
    private Button b;

    public A()
    {
        this.b = new Button();
    }

    public boolean onDeleteEvent(Widget w, Event e)
    {
        this.b.destroy();
        this.destroy();
        this.release();
        return false;
    }
}

should i use destroy and release functions like i do at this code? how to i finally release the objects?

java-gnome api website: http://java-gnome.sourceforge.net/4.0/doc/api/index.html?org/gnome/pango/package-summary.html

Based on this link: http://java-gnome.sourceforge.net/doc/api/4.1/org/gnome/gtk/Widget.html#destroy%28%29

It seems it will. Of course, like the text in italics says, it may not remove all references to the object in java just the GObject system. But otherwise, this looks correct. Once your reference to this goes out of scope, it should be completely dereferenced, along with all children you may have skipped.

I would also recommend if you are destroying a window with lots of children, and you plan on destroying every single one of them, call this.hide() as your first step in the onDeleteEvent. See: http://java-gnome.sourceforge.net/doc/api/4.1/org/gnome/gtk/Window.html

After reading through the docs looking for release() , I couldn't find it listed anywhere but in org.gnome.glib.Object, but there are not any actual direct methods from Object. I would recommend against using it.
