Specifies the optional DesignLayer instance associated with this visual element.
When a DesignLayer is assigned, a visual element must consider the visibility and alpha of its parent layer when ultimately committing its own effective visibility or alpha to its backing DisplayObject (if applicable).
A visual element must listen for layerPropertyChange
notifications from the associated layer parent. When the
effectiveAlpha or effectiveVisibility of the
layer changes, the element must then compute its own effective visibility
(or alpha) and apply it accordingly.
This property should not be set within MXML directly.
The designLayer property is not used for z-order control,
please see depth.

The horizontal distance in pixels from the center of the component to the center of the anchor target's content area.
The default anchor target is the container itself.
In layouts with advanced constraints, the anchor target can be a constraint column. Then the content area is the space between the preceding column (or container side) and the target column.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format "constraintColumnId:value". For example, "col1:10".

maskType:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
The mask type. Possible values are MaskType.CLIP, MaskType.ALPHA
or MaskType.LUMINOSITY.
Clip Masking
When masking in clip mode, a clipping masks is reduced to 1-bit. This means that a mask will not affect the opacity of a pixel in the source content; it either leaves the value unmodified, if the corresponding pixel in the mask is has a non-zero alpha value, or makes it fully transparent, if the mask pixel value has an alpha value of zero.
Alpha Masking
In alpha mode, the opacity of each pixel in the source content is multiplied by the opacity of the corresponding region of the mask. i.e., a pixel in the source content with an opacity of 1 that is masked by a region of opacity of .5 will have a resulting opacity of .5. A source pixel with an opacity of .8 masked by a region with opacity of .5 will have a resulting opacity of .4.
Luminosity Masking
A luminosity mask, sometimes called a 'soft mask', works very similarly to an alpha mask except that both the opacity and RGB color value of a pixel in the source content is multiplied by the opacity and RGB color value of the corresponding region in the mask.
Luminosity masking is not native to Flash but is common in Adobe Creative Suite tools like Adobe Illustrator and Adobe Photoshop. In order to accomplish the visual effect of a luminosity mask in Flash-rendered content, a graphic element specifying a luminosity mask actually instantiates a shader filter that mimics the visual look of a luminosity mask as rendered in Adobe Creative Suite tools.
Objects being masked by luminosity masks can set properties to control the RGB color value and clipping of the mask. See the luminosityInvert and luminosityClip attributes.

owner:DisplayObjectContainer| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
The owner of this IVisualElement object. By default, it is the parent of this IVisualElement object. However, if this IVisualElement object is a child component that is popped up by its parent, such as the drop-down list of a ComboBox control, the owner is the component that popped up this IVisualElement object.
This property is not managed by Flex, but by each component.
Therefore, if you use the PopUpManger.createPopUp() or
PopUpManger.addPopUp() method to pop up a child component,
you should set the owner property of the child component
to the component that popped it up.
The default value is the value of the parent property.

Specifies the width of a component as a percentage
of its parent's size. Allowed values are 0-100. The default value is NaN.
Setting the width or explicitWidth properties
resets this property to NaN.
This property returns a numeric value only if the property was previously set; it does not reflect the exact size of the component in percent.
This property is always set to NaN for the UITextField control.
When used with Spark layouts, this property is used to calculate the
width of the component's bounds after scaling and rotation. For example
if the component is rotated at 90 degrees, then specifying
percentWidth will affect the component's height.

An element must call this method when its layoutDirection changes or when its parent's layoutDirection changes. If they differ, this method is responsible for mirroring the element’s contents and for updating the element’s post-layout transform so that descendants inherit a mirrored coordinate system. IVisualElements typically implement mirroring by using postLayoutTransformOffsets to scale the X axis by -1 and to translate the x coordinate of the origin by the element's width.

protected function transformHeightForLayout(width:Number, height:Number, postLayoutTransform:Boolean = true):Number| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
Transform the element's size.
This method calculates the bounding box of the graphic element as if the element’s width/height properties were set to the passed in values. The method returns the height of the bounding box.
In general, this method is not for use by developers. Instead, you should implement or override the methods defined by the ILayoutElement interface.
Parametri
width:Number — The target pre-transform width.
| |
height:Number — The target pre-transform height.
| |
postLayoutTransform:Boolean (default = true)true, the returned bounding box is around the transformed element in its parent space (the element's transform is applied first).
|
Number — Returns the transformed height. Transformation is this element's
layout transformation matrix.

transformPointToParent | () | metodo |
public function transformPointToParent(localPosition:Vector3D, position:Vector3D, postLayoutPosition:Vector3D):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
A utility method to transform a point specified in the local
coordinates of this object to its location in the object's parent's
coordinates. The pre-layout and post-layout result will be set on
the position and postLayoutPosition
parameters, if they are non-null.
Parametri
localPosition:Vector3D — The point to be transformed, specified in the
local coordinates of the object.
| |
position:Vector3D — A Vector3D point that will hold the pre-layout
result. If null, the parameter is ignored.
| |
postLayoutPosition:Vector3D — A Vector3D point that will hold the post-layout
result. If null, the parameter is ignored.
