Method Detail

paintBefore

public boolean paintBefore(Context cx,
                           Node node)
Description copied from class: Lens
Effect: Graphics2D transformation matrix.

Overrides:
paintBefore in class Lens
Returns:
true to short-circuit to paintAfter at that node, bypassing painting of the subtree.
See Also:
Magnify

paintAfter

public boolean paintAfter(Context cx,
                          Node node)
Restores Graphics2D passed in paintBefore.

Overrides:
paintAfter in class Lens
Returns:
false so it composes with other lenses
See Also:
Ruler, Bounds, Cypher

semanticEventBefore

public boolean semanticEventBefore(SemanticEvent se,
                                   java.lang.String msg)
Description copied from class: Behavior
Round robin distribution to all behaviors. Message and clientData unpacked from SemanticEvent for convenience. Message is interned, so if you compare to a literal, you can use "==". Message can't be changed (it can be short-circuited out of), but client data can be mutated as it is passed along (so it's not passed as a parameter).

Overrides:
semanticEventBefore in class Behavior

semanticEventAfter

public boolean semanticEventAfter(SemanticEvent se,
                                  java.lang.String msg)
Description copied from class: Lens
Catch corresponding VFrame's windowClosed, windowRaised, ....

Overrides:
semanticEventAfter in class Lens
