All Implemented Interfaces:

Control

public class StandardReverseControl
extends MouseListenerControl

Reverse Control for StandardControlPanel. This Control is operational only if Controller supports negative rate.

Method Detail

createControlComponent

protected java.awt.Component createControlComponent(Skin skin)

Description copied from class: AbstractListenerControl

Subclasses defined this method to supply their GUI component. Subclasses must not return a null component.

Listener registration is handled by AbstractListenerControl.

Specified by:

createControlComponent in class AbstractListenerControl

Returns:

a Component

setOperational

protected void setOperational(boolean isOperational)

Set the state of the listener. If isOperational is passed as true, then the listener semantics are applied in response to mouse activity. Otherwise, the listener semantics are not applied. This is used to disable default semantics if client control panel simulates reversing media. In this case, setController will call setOperational with a true value.

Overrides:

setOperational in class AbstractListenerControl

Parameters:

isOperational - Set to true to make control operational.

setControllerHook

protected void setControllerHook(Controller controller)

Determine operational state of Control based on ability to support negative rate. If a negative rate is supported, I can use setRate to affect Controller reverse. Test here for negative rate and then reset old rate.

Overrides:

setControllerHook in class AbstractListenerControl

Parameters:

controller - Controller with which this control is associated.

createControlListener

protected java.util.EventListener createControlListener()

Description copied from class: AbstractListenerControl

Subclasses of AbstractListenerControl must define this method to supply an EventListener to handle events originating from control's component.

Subclasses must not return a null listener.

Specified by:

createControlListener in class AbstractListenerControl

Returns:

an EventListener
