SidebarSpan
public SidebarSpan()
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
move
public void move(Leaf ln,
int lo,
Leaf rn,
int ro)
- Description copied from class:
Span
- Save move, for interactive use: selection, annotations.
Sets start point < end point, handles necessary reformatting and repainting.
Reformats both old range and new range, as with style sheets and hardcode in subclasses, can't tell when that's not necessary.
(Or, moveq() + swapping endpoints if necessary + reformatting/repainting.)
- Overrides:
move
in class Span
restore
public void restore(ESISNode n,
java.util.Map<java.lang.String,java.lang.Object> attr,
Layer layer)
- Description copied from class:
Span
- Given ESIS subtree, pluck class-specific information from attributes, call super.restore() for locations.
Attributes named
start
and end
are reserved to hold Robust Location data.
- Overrides:
restore
in class Span
- See Also:
RobustLocation
destroy
public void destroy()
- Description copied from class:
Span
- Removes span from document and its layer.
Different from moveq(null), which removes from document tree but not from layer.
If caller will handle all reformatting and repainting, as during a batch destory(), first moveq(null) on span.
- Overrides:
destroy
in class Span
