Java: how to register a listener that listen to a JFrame movement

Question

How can you track the movement of a JFrame itself? I\'d like to register a listener that would be called back every single time JFrame.getLocation() is going to

Answer 1

You can register a HierarchyBoundsListener on your JFrame, or use a ComponentListener as suggested by others.

jf.getContentPane().addHierarchyBoundsListener(new HierarchyBoundsAdapter() {

    @Override
    public void ancestorMoved(HierarchyEvent e) {
        updateText(jf, jl);
    }
});

Answer 2

JFrame jf = new JFrame();
jf.addComponentListener(new ComponentListener() {...});

is what you are looking for, I think.

Answer 3

Using addComponentListener() with a ComponentAdapter:

jf.addComponentListener(new ComponentAdapter() {
    public void componentMoved(ComponentEvent e) {
        updateText(jf, jl);
    }
});
