Automatic change component width

[Guest]

I have an 'ImageButton' class.
When I change the text of ImageButton to a bigger text
e.g. "OK" -> "All Right!"
I want 'ImageButton' increases its width to keep the new text.
How can I do this?
My class implements these methods:
---------------
public class ImageButton extends Canvas implements MouseListener {
public void paint(Graphics g) { ... }
public Dimension getPreferredSize() { ... }
public Dimension getMinimumSize() { ... }
....
}

Since you bombard this newsgroup with beginner questions, first some
hints:

1. A newsgroup is not the right palce to learn a language and its
libraries. Consider working through the Java and GUI tutorials on the
Sun Java web site. Also consider buying a good book about Java.

2. comp.lang.java.programmer is not intended for beginner's questions.
The right group is comp.lang.java.help.

3. comp.lang.java.programmer is not intended for GUI questions. The
right group is comp.lang.java.gui.

4. If you don't like this suggestions, don't make an ass out of
yourself. Freaking out will only reduce your chances of getting an
answer in the future.

JButton is perfectly capable of displaying images.

Adjust the data that the get...Size() methods shall return, and
depending on your layout manager, revalidate / pack the container on
which you have placed the button.

both of getPreferredSize() & getMinimumSize() return correct width
for new text but component doesn't automatic resize.
Resize appears when I maximize and restore the Window
What methods simulate these events?

You are lacking essential knowledge about the Java GUI architecture. I
want to suggest again that you work through the GUI tutorials and get a
good book on the subject.
