Re: [OpenMap Users] map close notification?

Hi Dean, I put the following code in my subclass of Layer:

protected WindowListener windowListener;

/** Constructor */
public MyLayer() {
    /* Listener that cleans up this layer when its window is closed */
    windowListener = new WindowAdapter() {
      public void windowClosed ( WindowEvent e )
      {
        removed(null);
        super.windowClosed( e );
      }
    };
  }

  /** Look at the object received in a MapHandler status message and
connect to it if necessary. */
  public void findAndInit(Object someObj) {
      /** register window-closing listener on openmap window */
      if (someObj instanceof OpenMapFrame ) {
          ((OpenMapFrame) someObj).addWindowListener( windowListener );
      }
  }

  /** Look at the object received in a MapHandler status message and
disconnect from it if necessary. */
  public void findAndUndo(Object someObj) {
      if (someObj instanceof OpenMapFrame ) {
        ((OpenMapFrame) someObj).removeWindowListener( windowListener
);
      }
  }
