GUIEvent

The GUIEvent object is passed to the actionPerformed() method every time a GUI component generates an event. A GUIEvent has two fields, source and message. The methods getSource() and getMessage() will return those values. The event’s source is the component that generated the event, the message is a string that describes the nature of the event.

Method Summary

getSource()

  • The getSource() method returns the GUI component that generated the event.

getMessage()

  • The getMessage() method returns a string containing a description of the event.

Example

void actionPerformed (GUIEvent e) {
	print ("Component: " + e.getSource().getLabel());
	print ("Message: " + e.getMessage());
}
