- Subject: FYI: New AbstractButton test
- Bounce-to: "Roman Kennke" <kennke@aicas.com>
I added a test that checks that the AbstractButton.ButtonChangeListener
should call repaint().

gnu/testlet/javax/swing/AbstractButton/createChangeListener.java:
New test.
* gnu/testlet/javax/swing/AbstractButton/TestButton.java:
Test button class.
