Input events are delivered to listeners before they are processed normally by the source where they originated. This allows listeners and component subclasses to "consume" the event so that the source will not process them in their default manner. For example, consuming mousePressed events on a Button component will prevent the Button from being activated.<P><DL><DT><B>Since: </B><DD>1.1</DD><DT><B>See Also: </B><DD><A
