UI class for custom Button

Question

Hey frineds can any one tell me how can i make a UI class for my custom component?
Let me explain this is detail
I have a custom button called MyButton extended From JButton. I can change its appearance at runtime if i define my own UIClass called MyButtonUI which is extended from Basic ButtonUI.
One way to apply the ui to Mybutton is using method setUI().
But the much better way is to define our own look and feel class and setting defining buttonUI in it. This is done as follows
protected void initClassDefaults(UIDefaults table)
        super.initClassDefaults(table);
        table.put ("ButtonUI", "MyButtonUI");
}But this method sets the newly created UI to every swing button including the button used in comboBox !!
Can Any one tell me how can i set the ui that is applicable only to MyButton.

You should override the method getUIClassID() in your MyButton class which returns something like MyButtonUI. Then you put this in the default table:
protected void initClassDefaults(UIDefaults table) {
        super.initClassDefaults(table);
        String pkg = ...;
        table.put ("MyButtonUI", pkg + "MyButtonUI");
}Then you apply the UI only to your custom buttons.
