public abstract class InputEvent
extends ComponentEvent

The root event class for all component-level input events.
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.

The meta key modifier constant.

SHIFT_MASK
The shift key modifier constant.
