Constructor Details

BasicButtonListener

public BasicButtonListener(AbstractButton b)

Constructs a new instance of BasicButtonListener.

Parameters:: b - an abstract button

Method Details

propertyChange

public void propertyChange(PropertyChangeEvent e)

Description copied from interface: PropertyChangeListener

This method gets called when a bound property is changed.

Specified by:: propertyChange in interface PropertyChangeListener
Parameters:: e - A PropertyChangeEvent object describing the event source and the property that has changed.

checkOpacity

protected void checkOpacity(AbstractButton b)

Checks the opacity of the AbstractButton.

Parameters:: b - an abstract button

installKeyboardActions

public void installKeyboardActions(JComponent c)

Parameters:: c - a component

uninstallKeyboardActions

public void uninstallKeyboardActions(JComponent c)

Unregister default key actions.

Parameters:: c - a component

stateChanged

public void stateChanged(ChangeEvent e)

Description copied from interface: ChangeListener

Invoked when the target of the listener has changed its state.

Specified by:: stateChanged in interface ChangeListener
Parameters:: e - a ChangeEvent object

focusGained

public void focusGained(FocusEvent e)

Description copied from interface: FocusListener

Invoked when a component gains the keyboard focus.

Specified by:: focusGained in interface FocusListener
Parameters:: e - the event to be processed

focusLost

public void focusLost(FocusEvent e)

Description copied from interface: FocusListener

Invoked when a component loses the keyboard focus.

Specified by:: focusLost in interface FocusListener
Parameters:: e - the event to be processed

mouseMoved

public void mouseMoved(MouseEvent e)

Description copied from interface: MouseMotionListener

Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.

Specified by:: mouseMoved in interface MouseMotionListener
Parameters:: e - the event to be processed

mouseDragged

public void mouseDragged(MouseEvent e)

Description copied from interface: MouseMotionListener

Invoked when a mouse button is pressed on a component and then dragged. MOUSE_DRAGGED events will continue to be delivered to the component where the drag originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component).

Due to platform-dependent Drag&Drop implementations, MOUSE_DRAGGED events may not be delivered during a native Drag&Drop operation.

Specified by:: mouseDragged in interface MouseMotionListener
Parameters:: e - the event to be processed
