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.

ALT_MASK: The alt key modifier constant.
BUTTON1_MASK: The mouse button1 modifier constant.
BUTTON2_MASK: The mouse button2 modifier constant.
BUTTON3_MASK: The mouse button3 modifier constant.
CTRL_MASK: The control key modifier constant.
META_MASK: The meta key modifier constant.
SHIFT_MASK: The shift key modifier constant.

consume(): Consumes this event so that it will not be processed in the default manner by the source which originated it.
getModifiers(): Returns the modifiers flag for this event.
getWhen(): Returns the timestamp of when this event occurred.
isAltDown(): Returns whether or not the Alt modifier is down on this event.
isConsumed(): Returns whether or not this event has been consumed.
isControlDown(): Returns whether or not the Control modifier is down on this event.
isMetaDown(): Returns whether or not the Meta modifier is down on this event.
isShiftDown(): Returns whether or not the Shift modifier is down on this event.
