Java Swing JButton

I want to create button with custom look and feel. I have got different images to be set as background of button for normal, mouse over, mouse click, button disabled etc. I have created my own class, extending javax.swing.JButton and overrides paintComponent method. How can i change my button background for all the above given states.

You could create a custom button UI delegate. This blog entry: http://blog.elevenworks.com/?p=4 has an example for a custom tabbed pane, but the principle is the same. Extend BasicButtonUI, implement the custom rendering your want for the button, and then call setUI() on the button.

This will probably take longer to implement than using the existing button API methods to change the appearance, but it gives you a lot more control.

In addition to Steve De Caux's answer, you can:

  1. Add a MouseListener which changes an enum variable, let's call it state on your extended JButton

  2. In your overridden paintComponent take into consideration the current state and paint different backgrounds. Like

    if (!getModel().isEnabled()) {
} else if (state == ButtonState.MOUSE_OVER) {
} else if (state == ButtonState.MOUSE_CLICKED) {   
}

JButton has a series of simple set methods for rollover, pressed, selected, disabled and disabled selected states - for example

button.setPressedIcon(new ImageIcon("images/button-down.png")

the other methods are :

button.setRolloverIcon()
button.setSelectedIcon()
button.setRolloverSelectedIcon()
button.setDisabledIcon()
button.setDisabledSelectedIcon()

...have fun !

By the way, O'Reilly has a fun book called Swing Hacks with lots of little goodies for playing with swing : Swing Hacks
