Class LayoutFactory.BasicPropertyAdaptSupport

java.lang.Object
  info.monitorenter.gui.chart.controls.LayoutFactory.BasicPropertyAdaptSupport

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.util.EventListener

Enclosing class:

LayoutFactory

public static class LayoutFactory.BasicPropertyAdaptSupport
extends java.lang.Object
implements java.beans.PropertyChangeListener

Implementation for a PropertyChangeListener that adapts a wrapped JComponent to the following properties.

• background color ("background")
• foreground color (text color:"foreground")
• font ("font")

An instance will add itself as a PropertyChangeListener via Component.addPropertyChangeListener(PropertyChangeListener) on the component to adapt to.

However components should also be able to send property changes that make instances of this class garbage - collectable by removing them as a property change listener from them. The constructor given values mark those property changes that will cause instances of this class to remove themselves as a property change listener from the component listened to. These properties may be configured in glue code (as components are generic and should not be hard coded for tasks that are hooked to them).

Nested Class Summary

static interface	LayoutFactory.BasicPropertyAdaptSupport.IRemoveAsListenerFromComponentCondition Interface to handle the removal of the LayoutFactory.BasicPropertyAdaptSupport as a property change event listener.
static class	LayoutFactory.BasicPropertyAdaptSupport.RemoveAsListenerFromComponentIfTraceIsDropped Implementation based on the event Chart2D.PROPERTY_ADD_REMOVE_TRACE sent with an old value ITrace2D that has to be matched.
static class	LayoutFactory.BasicPropertyAdaptSupport.RemoveAsListenerFromComponentNever Implementation dummy that never will decide to remove the calling LayoutFactory.BasicPropertyAdaptSupport to be removed.

Field Summary

Constructor Detail

LayoutFactory.BasicPropertyAdaptSupport

public LayoutFactory.BasicPropertyAdaptSupport(java.awt.Component delegate,
                                               java.awt.Component adaptee,
                                               LayoutFactory.BasicPropertyAdaptSupport.IRemoveAsListenerFromComponentCondition quitListeningControl)

Creates an instance that will listen to basic properties ("font","foreground","background") on the given component and install those on the delegate component.

Parameters:

delegate - The component to adapt the properties on.

adaptee - The peer component delegate will be adapted to.

quitListeningControl - Used to decide when to stop listening on the component (adaptee).

Method Detail

finalize

protected void finalize()
                 throws java.lang.Throwable

Removes the listener for basic property changes from the component to adapt to.

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable - if something goes wrong cleaning up.
