making resizable components?

[Geoffrey Falk]

I am making a Panel using BorderLayout. In the
center of the layout is a custom Canvas.
When the user resizes the window, I want the
canvas to get resized automatically according
to its preferred size in the BorderLayout.
What is the mechanism to achieve this? I notice
that buttons, etc. already do it automatically.
Thanks!

Are you setting bounds on the Canvus or is it set to the BorderLayout as well?
What do you mean by Custom?

[Geoffrey Falk]

I don't know what you mean by setting bounds on the canvas. I am just setting an initial size for the canvas when it is created.
"custom Canvas" means I extended Canvas.

I have a solution, but it requires my panel to have something like this
addComponentListener(
new ComponentAdapter() {
public void componentResized(ComponentEvent e) {
canvas.requestSetSize(canvas.getPreferredSize());
}
}
);
which is ugly, and besides, Buttons don't need this trick!!
