onPreWindowClose not called by ExitCommand

[Patrick Vanhuyse]

When ExitCommand is called to quit, it calls Application.instance().close() which calls System.exit(0). The windows of the application are not closed cleanly.

Solution :

Change close() in Application:

    public void close() {
      if (windowManager.close())
        System.exit(0);
    }

Change close() in WindowManager:

    public boolean close() {
        List t = (List)((ArrayList)windows).clone();
        Iterator e = t.iterator();
        while (e.hasNext()) {
            ApplicationWindow window = (ApplicationWindow)e.next();
            if (!window.close())
              return false;
        }
        if (subManagers != null) {
            e = subManagers.iterator();
            while (e.hasNext()) {
                WindowManager wm = (WindowManager)e.next();
                if (!wm.close())
                  return false;
            }
        }
      return true;
    }

Change close() in ApplicationWindow:

    public boolean close() {
        boolean mustClose = getApplicationAdvisor().onPreWindowClose(this);
        if (mustClose) {
          control.dispose();
          control = null;
          if (windowManager != null) {
             windowManager.remove(this);
          }
          windowManager = null;
        }
        return mustClose;
    }

I incorporated these fixes and your other ApplicationWindow bug report regarding onWindowCreated. Thanks Patrick!
