Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

ButtonAsset is a subclass of the flash.display.SimpleButton class which represents button symbols that you embed in a Flex application from a SWF file produced by Flash. It implements the IFlexDisplayObject interface, which makes it possible for a SimpleButtonAsset to be displayed in an Image control, or to be used as a container background or a component skin.

This class is included in Flex for completeness, so that any kind of symbol in a SWF file produced by Flash can be embedded in a Flex application. However, Flex applications do not typically use embedded SimpleButtons. Refer to more commonly-used asset classes such as BitmapAsset for more information about how embedded assets work in Flex.

Property Detail

measuredHeight

property

measuredHeight:Number [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The measured height of this object.

This is typically hard-coded for graphical skins because this number is simply the number of pixels in the graphic. For code skins, it can also be hard-coded if you expect to be drawn at a certain size. If your size can change based on properties, you may want to also be an ILayoutManagerClient so a measure() method will be called at an appropriate time, giving you an opportunity to compute a measuredHeight.

Implementation
public function get measuredHeight():Number

measuredWidth

property

measuredWidth:Number [read-only]

Language Version:

ActionScript 3.0

Product Version:

move

()

method

public function move(x:Number, y:Number):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Moves this object to the specified x and y coordinates.

Parameters

	`x:Number` — The new x-position for this object.

	`y:Number` — The new y-position for this object.

setActualSize

()

method

public function setActualSize(newWidth:Number, newHeight:Number):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Sets the actual size of this object.

This method is mainly for use in implementing the updateDisplayList() method, which is where you compute this object's actual size based on its explicit size, parent-relative (percent) size, and measured size. You then apply this actual size to the object by calling setActualSize().

In other situations, you should be setting properties such as width, height, percentWidth, or percentHeight rather than calling this method.

Parameters

	`newWidth:Number` — The new width for this object.

	`newHeight:Number` — The new height for this object.
