Hello,

I would like to detect when my JFrame is resized. With WindowListerner I
know when it is maximised or inconified, but I cant find how to be noticed
of a simple resize.
Can you help me?

Francois

It is for a game. I need to center the display of the game in the window.

java.awt.event.ComponentListener

Other related events can be handled, if necessary, with WindowListener.

What happens to the rest of the space?

- If it is merely 'wasted space', I would suggest instead
to put the game in BorderLayout.CENTER, and lock the
size of the JFrame.
- If the game itself is resizable and a custom component,
again put it in BorderLayout.CENTER, but cache the size,
then check it each paint().
- If the game is resizable and made of standard components
or layouts, it should resize automatically.
