Examples of org.eclipse.swt.events.FocusListener

org.eclipse.swt.events.FocusListener
Classes which implement this interface provide methods that deal with the events that are generated as controls gain and lose focus.
After creating an instance of a class that implements this interface it can be added to a control using the addFocusListener method and removed using the removeFocusListener method. When a control gains or loses focus, the appropriate method will be invoked.
