|
| paint | () | method |
public function paint(g:YGraphics, ctx:IPaintContext):voidPerforms the actual painting into the given graphics context.
This implementation applies the set stroke and delegates the rendering to paintPath
and paintBends.
Parameters
g:YGraphics — The graphics context.
| |
ctx:IPaintContext — The paint context.
|

| paintBend | () | method |
protected function paintBend(g:YGraphics, ctx:IPaintContext, bend:IBend):voidDraws the bend assuming that the graphics context is correctly configured so that the bend is located at (0, 0).
Parameters
g:YGraphics — The graphics context.
| |
ctx:IPaintContext — The paint context.
| |
bend:IBend — The bend to draw.
|
| paintBends | () | method |
protected function paintBends(g:YGraphics, ctx:IPaintContext):void
Transforms the graphics context to paint in view coordinates and iterates over the edge's bends. For each
bend the graphics context is translated to the bend coordinates and the painting is delegated to
paintBend.

Parameters
oldDisplayObject:DisplayObject — The display object to update.
| |
context:IDisplayObjectContext — The context for which the display object should be updated.
|
DisplayObject — The updated display object or a completely new display object.
