Constructor.
| draw | () | method |
override protected function draw(g:Graphics):void| Language Version : | ActionScript 3.0 |
| Product Version : | Flex 4 |
| Runtime Versions : | Flash Player 10, AIR 1.5 |
Draw the element. This is the second of three steps taken during the drawing
process. Override this method to implement your drawing. The stroke
(and fill, if applicable) have been set in the beginDraw() method.
Your override should only contain calls to drawing methods such as
moveTo(), curveTo(), and drawRect().
Parameters
g:Graphics — The graphic element to draw.

| getBoundsXAtSize | () | method |
override public function getBoundsXAtSize(width:Number, height:Number, postLayoutTransform:Boolean = true):Number| Language Version : | ActionScript 3.0 |
| Product Version : | Flex 4 |
| Runtime Versions : | Flash Player 10, AIR 1.5 |
Returns the x coordinate of the element's bounds at the specified element size.
This method is typically used by layouts during a call to the
measure() method to predict what
the element position will be, if the element is resized to particular dimensions.
Parameters
width:Number — The element's bounds width, or NaN to use the preferred width.
| |
height:Number — The element's bounds height, or NaN to use the preferred height.
| |
postLayoutTransform:Boolean (default = true)postLayoutTransform is true, the method returns
x coordinate of the element's bounding box top-left corner.
The bounding box is in element's parent coordinate space and is calculated
from the specified bounds size, layout position and layout transform matrix.
|
Number — The x coordinate of the element's bounds at the specified element size.
|
| getBoundsYAtSize | () | method |
override public function getBoundsYAtSize(width:Number, height:Number, postLayoutTransform:Boolean = true):Number| Language Version : | ActionScript 3.0 |
| Product Version : | Flex 4 |
| Runtime Versions : | Flash Player 10, AIR 1.5 |
Returns the y coordinate of the element's bounds at the specified element size.
This method is typically used by layouts during a call to
the measure() to predict what
the element position will be, if the element is resized to particular dimensions.
Parameters
width:Number — The element's bounds width, or NaN to use the preferred width.
| |
height:Number — The element's bounds height, or NaN to use the preferred height.
| |
postLayoutTransform:Boolean (default = true)postLayoutTransform is true, the method returns
the y coordinate of the element's bounding box top-left corner.
The bounding box is in element's parent coordinate space and is calculated
from the specified bounds size, layout position and layout transform matrix.
|
Number — The y coordinate of the element's bounds at the specified element size.
