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().

Parametry

g:Graphics — The graphic element to draw.

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.

Parametry

	`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`) — When `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.
