Class | public class SWFNodeStyleRenderer |
Inheritance | SWFNodeStyleRenderer AbstractNodeStyleRenderer AbstractStyleRenderer Object |
INodeStyleRenderer
implementation that
adds SWF node representations to the display list or updates these SWFs.
Method | Defined By | ||
---|---|---|---|
[override]
Returns a tight rectangular area where the whole rendering
would fit into. | SWFNodeStyleRenderer | ||
createDisplayObject(context:IDisplayObjectContext):DisplayObject [override]
Creates a new DisplayObject from scratch. | SWFNodeStyleRenderer | ||
Configures the style and item parameters,
calls configure and returns this. | AbstractStyleRenderer | ||
Configures the style and item parameters,
does not call configure and returns this. | AbstractStyleRenderer | ||
Configures the style and item parameters,
calls configure and returns this. | AbstractStyleRenderer | ||
Configures the style and item parameters,
calls configure and returns this. | AbstractStyleRenderer | ||
getIntersection(innerX:Number, innerY:Number, outerX:Number, outerY:Number, intersectionPoint:IPointSetter):Boolean
Finds an intersection for the current item using the style. | AbstractNodeStyleRenderer | ||
Configures the style and item parameters,
calls configure and returns this. | AbstractStyleRenderer | ||
Returns the outline of the shape using the node's layout. | AbstractNodeStyleRenderer | ||
Configures the style and
item parameters,
calls configure and returns this. | AbstractNodeStyleRenderer | ||
[override]
Installs the model in the canvas at the given group using the styleDescriptor. | SWFNodeStyleRenderer | ||
isHit(x:Number, y:Number, ctx:ICanvasContext):Boolean [override]
Hit tests the item by trying to apply the flash internal hit testing. | AbstractNodeStyleRenderer | ||
[override]
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. | AbstractNodeStyleRenderer | ||
isInside(x:Number, y:Number):Boolean
Checks whether the given coordinate lies within the shape's geometric bounds. | AbstractNodeStyleRenderer | ||
Calls configure and tests the item using the style
for a visible intersection with the clip bounds. | AbstractStyleRenderer | ||
lookup(type:Class):Object [override]
Implements the ILookup interface. | SWFNodeStyleRenderer | ||
updateDisplayObject(oldDisplayObject:DisplayObject, context:IDisplayObjectContext):DisplayObject [override]
Updates the given DisplayObject or creates a new one. | SWFNodeStyleRenderer |
Method | Defined By | ||
---|---|---|---|
configure():void [override]
This is an empty implementation of the AbstractStyleRenderer.configure
method. | AbstractNodeStyleRenderer | ||
createRenderDataCache():Object
Creates an Object which reflects the current state of the style and the model item. | SWFNodeStyleRenderer | ||
[override]
Factory method for the StyleDescriptor property. | AbstractNodeStyleRenderer | ||
setItem(item:IModelItem):void
Called by the various descriptor getters to initialize the item. | AbstractStyleRenderer | ||
setStyle(style:IVisualStyle):void
Called by the various descriptor getters to initialize the style. | AbstractStyleRenderer |
calculateBounds | () | method |
override public 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)
|
IRectangle — The bounds or null to indicate an unbound area
|
createDisplayObject | () | method |
override public function createDisplayObject(context:IDisplayObjectContext):DisplayObject
Creates a new DisplayObject
from scratch.
Parameters
context:IDisplayObjectContext — The context for which the display object is created.
|
DisplayObject — A DisplayObject .
|
createRenderDataCache | () | method |
protected function createRenderDataCache():Object
Creates an Object which reflects the current state of the style and the model item.
ReturnsObject — An Object which reflects the current state of the style and the model item.
|
install | () | method |
override public function install(canvas:CanvasComponent, group:ICanvasObjectGroup, modelItem:IModelItem):Array
Installs the model in the canvas at the given group using the styleDescriptor
.
Parameters
canvas:CanvasComponent | |
group:ICanvasObjectGroup | |
modelItem:IModelItem |
Array |
lookup | () | method |
override public function lookup(type:Class):Object
Implements the ILookup
interface.
This method will be used by default if getContext
has been queried for a
lookup implementation.
Note that it cannot be assumed that configure
has already been invoked.
However, normally item
and style
will be correctly configured
if invoked directly after getContext
.
Subclass implementations should make sure to configure this instance before they return this
as a result
of a successful lookup.
Parameters
type:Class — The type to query for
|
Object — An implementation of the given type or null
|
updateDisplayObject | () | method |
override public function updateDisplayObject(oldDisplayObject:DisplayObject, context:IDisplayObjectContext):DisplayObject
Updates the given DisplayObject
or creates a new one.
Implementors can decide whether they update the given display object or create a new one. Updating can mean re-rendering or updating size and/or coordinates.
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.
