Method Detail

setColor

public void setColor(java.awt.Color c)

paintBefore

public boolean paintBefore(Context cx,
                           Node n)
Description copied from class: Behavior
A tree walk protocol, called before observed node has been painted. Called in same coordinate space as node's painting. Can be used draw special background, but usual background setting is done by spans or style sheets.

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

paintAfter

public boolean paintAfter(Context cx,
                          Node n)
Description copied from class: Behavior
A tree walk protocol, called before observed node has been painted. Called in same coordinate space as node's painting. Use to draw annotations at node's location. For instance, Search uses this to decorate the scrollbar (a type of node) with location of matches.

Overrides:
paintAfter in class Behavior

appearance

public boolean appearance(Context cx,
                          boolean all)
Description copied from interface: ContextListener
Resets the graphics context every time the object is added to or dropped from the set active over the portion of the document being drawn. These behaviors can come from the style sheet, be ad hoc spans, be lenses, or come from elsewhere. Should be fast.

Specified by:
appearance in interface ContextListener
Overrides:
appearance in class Span
all - all attributes or exclude those that are not inherited
