source

property 
source:Object

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The source used for the bitmap fill. The fill can render from various graphical sources, including the following:

  • A Bitmap or BitmapData instance.
  • A class representing a subclass of DisplayObject. The BitmapFill instantiates the class and creates a bitmap rendering of it.
  • An instance of a DisplayObject. The BitmapFill copies it into a Bitmap for filling.
  • The name of an external image file.

If you use an image file for the source, it can be of type PNG, GIF, or JPG.

To specify an embedded image source, you can use the @Embed directive, as the following example shows:

      source="@Embed('<i>image_location</i>')"
      

The image location can be specified via a URL, URLRequest, or file reference. If it is a file reference, its location is relative to the location of the file that is being compiled.

The BitmapImage class is designed to work with embedded images or images that are loaded at run time.

If the source is a Bitmap or BitmapData instance or is an external image file, it is the responsibility of the caller to dispose of the source once it is no longer needed. If ImageLoader created the BitmapData instance, then it will dispose of the BitmapData once the source has changed.

This property can be used as the source for data binding. When this property is modified, it dispatches the sourceChanged event.

Method Detail

commitProperties

()method
override protected function commitProperties():void

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Processes the properties set on the element. This is an advanced method that you might override when creating a subclass.

You do not call this method directly. Flex calls the commitProperties() method when you use the addElement() method to add an element to an IGraphicElementContainer container such as Group, or when you call the invalidateProperties() method of the element. Calls to the commitProperties() method occur before calls to the measure() method. This lets you set property values that might be used by the measure() method.

Some elements have properties that interact with each other. It is often best at startup time to process all of these properties at one time to avoid duplicating work.

measure

()method 
override protected function measure():void

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Calculates the default size of the element. This is an advanced method that you might override when creating a subclass of GraphicElement.

You do not call this method directly. Flex calls the measure() method when the element is added to an IGraphicElementContainer container such as Group using the addElement() method, and when the element's invalidateSize() method is called.

By default you set both explicit height and explicit width of an element, Flex does not call the measure() method, even if you explicitly call the invalidateSize() method. To override this behavior, override skipMeasure() method.

In your override of this method, you must set the measuredWidth and measuredHeight properties to define the default size. You can optionally set the measuredX and measuredY properties to define the default measured bounds top-left corner relative to the origin of the element.

The conceptual point of measure() is for the element to provide its own natural or intrinsic bounds as a default. Therefore, the measuredWidth and measuredHeight properties should be determined by factors such as:

  • The amount of text the component needs to display.
  • The size of a JPEG image that the component displays.

In some cases, there is no intrinsic way to determine default values. For example, a simple GreenCircle element might simply set measuredWidth = 100 and measuredHeight = 100 in its measure() method to provide a reasonable default size. In other cases, such as a TextArea, an appropriate computation (such as finding the right width and height that would just display all the text and have the aspect ratio of a Golden Rectangle) might be too time-consuming to be worthwhile.

The default implementation of measure() sets the values of the measuredWidth, measuredHeight, measuredX, and measuredY properties to 0.

updateDisplayList

()method 
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Draws the element and/or sizes and positions its content. This is an advanced method that you might override when creating a subclass of GraphicElement.

You do not call this method directly. Flex calls the updateDisplayList() method when the component is added to an IGraphicElementContainer container such as Group using the addElement() method, and when the element's invalidateDisplayList() method is called.

This method is where you would do programmatic drawing using methods on the elements's displayObject such as graphics.drawRect().

Parameters

unscaledWidth:Number — Specifies the width of the component, in pixels, in the component's coordinates, regardless of the value of the scaleX property of the component.
 
unscaledHeight:Number — Specifies the height of the component, in pixels, in the component's coordinates, regardless of the value of the scaleY property of the component.
