/** * Change the default button of the root pane of the specified * component. * * @param component the component whose root pane's default button * should be changed.

Otherwise the default button * is set to none */ private void changeDefault(Component component, boolean setDefault) { if (component instanceof JButton) { JButton button = (JButton) component; JRootPane parent = button.getRootPane(); /* * In some conditions, when pushing the button results * in it being removed from the root container, a focus * event can be processed after the button (or its parents) * has been removed, so we need to check for a non-null * root for a focused button, even though that seems * nonsensical. */ if (parent != null) { if (setDefault) { parent.setDefaultButton(button); } else { parent.setDefaultButton(null); } } } }
