This is javax.swing.plaf.basic.BasicButtonListener:
public void mousePressed(MouseEvent e) {
if ( SwingUtilities.isLeftMouseButton(e) ) {
AbstractButton b = (AbstractButton) e.getSource();
ButtonModel model = b.getModel();
if (!model.isEnabled()) {
// Disabled buttons ignore all input...
return;
}
// But because of the mouseDragged hack above, we can't do setArmed
// in mouseEnter. As a workaround, set it here just before setting
// focus.
model.setArmed(true);
model.setPressed(true);
if(!b.hasFocus()) {
b.requestFocus();
}
}
}
I suggest overriding your ButtonUI to return a subclass of
BasicButtonListener or MetalButtonListener (assuming that you are using
Metal L&F), getting mousePressed to set a flag (and mouseReleased to unset
it), and changing the above test to (!model.isEnabled || (flag == true)).
Only subclass if you need to create a new type of button. (Not the case,
here.)
