Classpublic class GridSnapResultPaintable
InheritanceGridSnapResultPaintable Inheritance Object
Implements IPaintable

This class visualizes the snapping of a moved object to a grid point. It paints '+' symbols at the snappedGridPoint as well as at all eight grid points around it using horizontalSpacing and verticalSpacing of the gridInfo to determine their position. If the spacing in view coordinates between the snappedGridPoint and any of these grid points is smaller then the minimumSpacing, a grid point further away from the snappedGridPoint is used instead to fulfill the minimumSpacing. This way the snap result visualization adapts to the current zoom level but does place it's painted points only on grid coordinates.

Method Detail
paint()method
public function paint(g:YGraphics, ctx:IPaintContext):void

Paints '+' symbols at the snappedGridPoint as well as at all eight grid points around it using horizontalGridWidth and verticalGridWidth to determine their position. It delegates to paintGridPoint to paint each of these grid points.

Parameters

g:YGraphics — The graphics object to paint upon.
 
ctx:IPaintContext — The paint context.
