Constructor Detail

BasicButtonListener

public BasicButtonListener(AbstractButton b)

Method Detail

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent e)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

checkOpacity

protected void checkOpacity(AbstractButton b)

installKeyboardActions

public void installKeyboardActions(JComponent c)

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

uninstallKeyboardActions

public void uninstallKeyboardActions(JComponent c)

Unregister's default key actions

getActionMap

ActionMap getActionMap(AbstractButton b)

Returns the ActionMap to use for b. Called as part of installKeyboardActions.

getInputMap

InputMap getInputMap(int condition,
                     JComponent c)

Returns the InputMap for condition condition. Called as part of installKeyboardActions.

createActionMap

ActionMap createActionMap(AbstractButton c)

Creates and returns the ActionMap to use for the button.

updateMnemonicBinding

void updateMnemonicBinding(AbstractButton b)

Resets the binding for the mnemonic in the WHEN_IN_FOCUSED_WINDOW UI InputMap.

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

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

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

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

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

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

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

mouseEntered

public void mouseEntered(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse enters a component.

Specified by:

mouseEntered in interface MouseListener

mouseExited

public void mouseExited(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse exits a component.

Specified by:

mouseExited in interface MouseListener
