Window resize event?

Question

I'm writing a simple painting program using Java, and I want some method to be called whenever the JFrame component is resized. However I can't find any method like windowResizedListener or an event like windowResizedEvent. What can I do?!

Implement a ComponentAdapter with componentResized():

frame.addComponentListener(new ComponentAdapter() {
    public void componentResized(ComponentEvent componentEvent) {
        // do stuff
    }
});

Overriding particular methods of ComponentAdapter is a convenient alternative to implementing all the methods of ComponentListener. Several examples seen here illustrate the "convenience for creating listener objects" mentioned in the API.

You have to use componentResized from ComponentListener.
