public class FocusEvent
extends AWTEvent

Description

This event indicates that a techexplorer instance has gained or lost focus. At most one graphical component can have the focus at any given time.

Current Restriction: There is no distinction between permanent and temporary change of focus events.

In order for a Java object to receive focus notifications, the Java object must register a class that implements the ibm.techexplorer.awt.event.FocusListener interface. Alternatively, a focus listener could make use of a ibm.techexplorer.awt.event.FocusAdaptor class.

See Also:: AWTEvent, FocusListener, FocusAdaptor

`static int`	`FOCUS_GAINED` Event identifier indicating that a techexplorer instance has gained focus.
