Constructor Detail

BasicButtonListener

public BasicButtonListener(AbstractButton b)

Constructs a new instance of BasicButtonListener.

Parameters:

b - an abstract button

Method Detail

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)

Register default key actions: pressing space to "click" a button and registering the keyboard mnemonic (if any).

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

mouseClicked

public void mouseClicked(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse button has been clicked (pressed and released) on a component.

Specified by:

mouseClicked in interface MouseListener

Parameters:

e - the event to be processed

mousePressed

public void mousePressed(MouseEvent e)

Description copied from interface: MouseListener

Invoked when a mouse button has been pressed on a component.

Specified by:

mousePressed in interface MouseListener

Parameters:

e - the event to be processed

mouseReleased

public void mouseReleased(MouseEvent e)

Description copied from interface: MouseListener

Invoked when a mouse button has been released on a component.

Specified by:

mouseReleased in interface MouseListener

Parameters:

e - the event to be processed

mouseEntered

public void mouseEntered(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse enters a component.

Specified by:

mouseEntered in interface MouseListener

Parameters:

e - the event to be processed

mouseExited

public void mouseExited(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse exits a component.

Specified by:

mouseExited in interface MouseListener

Parameters:

e - the event to be processed
