Property detail

layout

property

layout:IRectangle [read-only]

Returns the INode.layout of the node this renderer is currently configured for.

Implementation
public function get layout():IRectangle

_nodeStyleDescriptor

property

protected var _nodeStyleDescriptor:ICanvasObjectDescriptor

Method detail

calculateBounds

()

method

public override function calculateBounds(scratch:IMutableRectangle, ctx:ICanvasContext):IRectangle

Returns a tight rectangular area where the whole rendering would fit into.

Implementations can use the scratch rectangle to put their results in and return it as the result of the operation. Client has to always provide a non-null instance as a parameter. They may however decide to return an internally cached or dynamically created IRectangle implementation and disregard the scratch parameter. If calculating the bounds is too expensive or the painting is not bound to a certain area, this method may return null. If nothing is painted, this method should return an empty rectangle, where either or both the width and height is non-positive or ImmutableRectangle.Empty.

Parameters

	`scratch:IMutableRectangle` — An instance that can optionally be used to fill with the corresponding values and be returned

	`ctx:ICanvasContext` — The context to calculate the bounds for (currently not used)

Returns

IRectangle — The bounds or null to indicate an unbound area

configure

()

method

protected override function configure():void

This is an empty implementation of the AbstractStyleRenderer.configure method. Subclasses should override this.

createStyleDescriptor

()

method

protected override function createStyleDescriptor():ICanvasObjectDescriptor

Factory method for the StyleDescriptor property. This method will be called upon first access to the styleDescriptor property.

Returns

ICanvasObjectDescriptor — An ICanvasObjectDescriptor instance that will delegate to this instance's methods

getIntersection

()

method

public function getIntersection(innerX:Number, innerY:Number, outerX:Number, outerY:Number, intersectionPoint:IPointSetter):Boolean

Finds an intersection for the current item using the style.

This implementation returns the intersection for the layout.

Parameters

	`innerX:Number` — The x coordinate of the point inside the node.

	`innerY:Number` — The y coordinate of the point inside the node.

	`outerX:Number` — The x coordinate of the point outside the node.

	`outerY:Number` — The y coordinate of the point outside the node.

	`intersectionPoint:IPointSetter` — The point to store the coordinates of the intersection in.

Returns

Boolean — true if an intersection was actually found

getOutline

()

method

public function getOutline():GeneralPath

Returns the outline of the shape using the node's layout.

Returns

GeneralPath — The outline of the bounds of the node.

getShapeGeometry

()

method

public function getShapeGeometry(node:INode, style:INodeStyle):IShapeGeometry

Configures the style and item parameters, calls configure and returns this.

Parameters


node:INode — The node to retrieve the shape geometry for. The value will
      be stored in the the item 
      field by setItem
      


 


style:INodeStyle — The style to associate with the node. The value will
      be stored in the style 
      field by setStyle.
      



Returns


IShapeGeometry — 
                        this





isHit () method  



public override function isHit(x:Number, y:Number, ctx:ICanvasContext):Boolean
   
   Hit tests the item by trying to apply the flash internal hit testing.
   

   This implementation does not take ICanvasContext.hitTestRadius into account.
   
   Parameters


x:Number


 


y:Number


 


ctx:ICanvasContext



Returns


Boolean






isInBox () method  



public override function isInBox(box:IRectangle, ctx:ICanvasContext):Boolean
   
   
   Returns true if the corresponding 
   item is considered to intersect the given rectangular box.

   This method may return false if the item cannot be
   selected using a selection marquee or optionally if the
   item is only partially contained within the box.
   
Parameters


box:IRectangle — The box describing the marquee's bounds
   


 


ctx:ICanvasContext — The current canvas context
   



Returns


Boolean — true if the item is considered to be captured by the marquee
   






isInside () method  



public function isInside(x:Number, y:Number):Boolean
   Checks whether the given coordinate lies within the shape's geometric bounds.
   

   This implementation checks for containment in the layout.
   
   Parameters


x:Number — The x coordinate of the point to test.
   


 


y:Number — The y coordinate of the point to test.
   



Returns


Boolean — True if the point lies within the geometry of the rendering.
   






paint () method  



public override function paint(g:YGraphics, ctx:IPaintContext):void
   
   
   Performs the actual painting into the given graphics context.
   
Parameters


g:YGraphics — The graphics context to paint into
   


 


ctx:IPaintContext — Currently not used
