Serialized Fields

bdata

byte[] bdata

id

int id

The event's id.

See Also:

AWTEvent.getID() , AWTEvent.AWTEvent(java.lang.Object, int)

consumed

boolean consumed

Controls whether or not the event is sent back down to the peer once the source has processed it - false means it's sent to the peer; true means it's not. Semantic events always have a 'true' value since they were generated by the peer in response to a low-level event.

firstLine

Component    firstLine

A relative positioning constant, that can be used instead of north, south, east, west or center. mixing the two types of constants can lead to unpredicable results. If you use both types, the relative constants will take precedence. For example, if you add components using both the NORTH and BEFORE_FIRST_LINE constants in a container whose orientation is LEFT_TO_RIGHT, only the BEFORE_FIRST_LINE will be layed out. This will be the same for lastLine, firstItem, lastItem.

lastLine

Component    lastLine

A relative positioning constant, that can be used instead of north, south, east, west or center. Please read Description for firstLine.

firstItem

Component    firstItem

A relative positioning constant, that can be used instead of north, south, east, west or center. Please read Description for firstLine.

lastItem

Component    lastItem

A relative positioning constant, that can be used instead of north, south, east, west or center. Please read Description for firstLine.
