private class ActionPane.RolloverButton
extends javax.swing.JButton

A specialised rollover-enabled button which corrects some quirks/annoyances within JButton, making it more suited for use with graphical buttons. This is created as a result of the 'rollover1' bug (see MultiMahjong/docs/bugs/rollover1.html for a description of the bug).

Constructor Detail

ActionPane.RolloverButton

public ActionPane.RolloverButton()

Creates an instance of a specialised rollover-enabled JButton. This constructor overrides a few default settings which make graphical buttons appear ugly and are perhaps more suited to text-only buttons.

Method Detail

setEnabled

public void setEnabled(boolean b)

Overrides the setEnabled method in JButton, correcting a subtle bug in relation to rollover buttons. If setEnabled(false) is invoked on a JButton while it is in the RollOver state, the subsequent call to setEnabled(true) will re-enable the button again in the RollOver state even though the mouse cursor is not over the button. This bug is corrected here by setting the RollOver state to false explicitly.
