Method Summary |
boolean |
appearance(Context cx,
boolean all)
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. |
int |
getPriority()
Self-reported priority relative to others of the same class, e.g., other spans. |
void |
moveq(Leaf ln,
int lo,
Leaf rn,
int ro)
"move quick" just updates summaries, so more efficient than move(), if caller:
guarantees that first node comes before second node (so the system doesn't have to spend time checking this), and
handles all reformatting and repainting (including marking tree nodes dirty)
Useful using during initial tree builds, when adding spans and formatting in batch(es). |
boolean |
paintBefore(Context cx,
Node start)
A tree walk protocol, called before observed node has been painted. |
boolean |
semanticEventAfter(SemanticEvent se,
java.lang.String msg)
Intert to events. |
boolean |
semanticEventBefore(SemanticEvent se,
java.lang.String msg)
Intert to events (so don't get double entries in popups). |
void |
setLabel(java.lang.String label)

paintBefore
public boolean paintBefore(Context cx,
Node start)
- 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.
getPriority
public int getPriority()
- Description copied from interface:
ContextListener
- Self-reported priority relative to others of the same class, e.g., other spans.
Use the constants defined here, such as
ContextListener.PRIORITY_LENS
, modified by ContextListener.LITTLE
/ContextListener.SOME
/{#link LOT}.
- Specified by:
getPriority
in interface ContextListener
- Overrides:
getPriority
in class Span
moveq
public void moveq(Leaf ln,
int lo,
Leaf rn,
int ro)
- Description copied from class:
Span
- "move quick" just updates summaries, so more efficient than move(), if caller:
- guarantees that first node comes before second node (so the system doesn't have to spend time checking this), and
- handles all reformatting and repainting (including marking tree nodes dirty)
Useful using during initial tree builds, when adding spans and formatting in batch(es).
Checks that endpoint offsets are valid, that is, >=0 and

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.

public boolean semanticEventAfter(SemanticEvent se,
java.lang.String msg)
- Intert to events.
