Java AWT/Swing: Get notified on change of position/size of my window

Question

I've got a window and I would like to get notified when the position or the size has changed. Which type of listener is the best to take?

WindowListener didn't work for me.

Answer 1

您可以使用具有componentResized和componentMoved方法的ComponentListener 。

Answer 2

You might want to try the HierarchyBoundsListene r

        myJFrame.getContentPane().addHierarchyBoundsListener(new HierarchyBoundsListener(){

        public void ancestorMoved(HierarchyEvent e) {
            doSomething();          
        }

        public void ancestorResized(HierarchyEvent e) {
            doSomethingElse();
        }   

see http://java.sun.com/docs/books/tutorial/uiswing/events/eventsandcomponents.html for a full list of listeners that all swing components support.
