Class RequestFocusListener

java.lang.Object

com.inductiveautomation.factorypmi.designer.listeners.RequestFocusListener

All Implemented Interfaces:

java.util.EventListener, javax.swing.event.AncestorListener

public class RequestFocusListener
extends java.lang.Object
implements javax.swing.event.AncestorListener

Convenience class to request focus on a component. When the component is added to a realized Window then component will request focus immediately, since the ancestorAdded event is fired immediately. When the component is added to a non realized Window, then the focus request will be made once the window is realized, since the ancestorAdded event will not be fired until then. Using the default constructor will cause the listener to be removed from the component once the AncestorEvent is generated. A second constructor allows you to specify a boolean value of false to prevent the AncestorListener from being removed when the event is generated. This will allow you to reuse the listener each time the event is generated.
