Proxy object that represents the action in the IDE.

 

Constructor Detail

DefaultAction

public DefaultAction()
Constructor that obtains the proxy object for this action and stores it internally. Use the getProxy() method to retrieve the proxy. If the proxy is not found via ActionSvc.I.getAction(), a proxy is created.

DefaultAction

public DefaultAction(String name, 
                     Icon icon)
Constructor that sets the name of the action and an icon in the proxy. This constructor first obtains the proxy object for this action and stores it internally. Use the getProxy() method to retrieve the proxy. If the proxy is not found via the ActionSvc.I.getAction method, a proxy is created.

DefaultAction

public DefaultAction(String name)
Constructor that sets the name of the action in the proxy. This constructor first obtains the proxy object for this action and stores it internally. Use the getProxy() method to retrieve the proxy. If the proxy is not found via ActionSvc.I.getAction(), a proxy is created.
 

Method Detail

getProxy() Method

public IActionProxy getProxy()
Gets the proxy object for this action. The proxy object contains all of the UI information for the action. The proxy object may be null if this action is not registered with the action service (via an extension.xml) when the proxy has been created through the ActionSvc.I.createProxy method.


propertyChange(PropertyChangeEvent) Method

public void propertyChange(PropertyChangeEvent e)
Updates the state of this action using the given property change event. The action service automatically propagates the following change events to all actions: Application.PROP_ActiveWorkspace, Application.PROP_ActiveProject, and Application.PROP_ActiveDocumentView. This implementation performs no work. Subclasses should override this method if the enabled state of the action can change as the various application properties change.

Parameters

e
Property change event to respond to. This may be null if a refresh is forced. Actions may choose to simply ignore this case. They are guaranteed to receive notification for each of the events listed above. If their state depends solely on those, null may be ignored (as long as the initial state is properly set).
