property
baseline:Object

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

The vertical distance in pixels from the anchor target to the control's baseline position.

By default the anchor target is the top edge of the container's content area. In layouts with advanced constraints, the target can be a constraint row.

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: "anchorTargetName:value". For example, "row1:10".



Implementation
    public function get baseline():Object
    public function set baseline(value:Object):void

baselinePosition

property 
baselinePosition:Number  [read-only]

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

The y-coordinate of the baseline of the first line of text of the component.

This property is used to implement the baseline constraint style. It is also used to align the label of a FormItem with the controls in the FormItem.

Each component should override this property.



Implementation
    public function get baselinePosition():Number

blendMode

property 
blendMode:String[override]

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

bottom:Object

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

The vertical distance in pixels from the bottom edge of the component to the anchor target's bottom edge.

By default the anchor target is the container's content area. In layouts with advanced constraints, the target can be a constraint row.

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: "anchorTargetName:value". For example, "row1:10".

depth

property 
depth:Number

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

Determines the order in which items inside of containers are rendered. Spark containers order their items based on their depth property, with the lowest depth in the back, and the higher in the front. Items with the same depth value appear in the order they are added to the container.



Implementation
    public function get depth():Number
    public function set depth(value:Number):void

designLayer

property 
designLayer:DesignLayer

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

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.



Implementation
    public function get designLayer():DesignLayer
    public function set designLayer(value:DesignLayer):void

hasLayoutMatrix3D

property 
hasLayoutMatrix3D:Boolean  [read-only]

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

Contians true if the element has 3D Matrix.

Use hasLayoutMatrix3D instead of calling and examining the return value of getLayoutMatrix3D() becasue that method returns a valid matrix even when the element is in 2D.



Implementation
    public function get hasLayoutMatrix3D():Boolean

mask

property 
mask:DisplayObject[override]

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

Sets the mask. The mask will be added to the display list. The mask must not already on a display list nor in the elements array.

maskType

property 
maskType:String

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: 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.

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

owner

property 
owner:DisplayObjectContainer

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: 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.



Implementation
    public function get owner():DisplayObjectContainer

percentHeight

property 
percentHeight:Number

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

Number that specifies the height of a component as a percentage of its parent's size. Allowed values are 0-100. Setting the height or explicitHeight 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.



Implementation
    public function get percentHeight():Number
    public function set percentHeight(value:Number):void

percentWidth

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

Defines the vertical space that the graphic uses in the layout. When you set this value, the content is not scaled. Whereas, if you specify the value of the height property, the content is scaled.

There are two cases where this can be useful: 1) Specify a viewHeight larger than the natural size of the content. You might do this so that the graphic takes up more space than its visual size. 2) Specify a viewHeight that is smaller than the natural size of the content. You might do this if your graphic has extra chrome or a border that extends past the edges of the graphic. In this scenario, be sure to disable clipping in your layout.

visible

property 
visible:Boolean[override]

Controls the visibility of this visual element. If true, the object is visible.

If an object is not visible, but the includeInLayout property is set to true, then the object takes up space in the container, but is invisible.

If visible is set to true, the object may not necessarily be visible due to its size and whether container clipping is enabled.

Setting visible to false, prevents the component from getting focus.

setLayoutMatrix

()method 
public function setLayoutMatrix(value:Matrix, invalidateLayout:Boolean):void

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

Sets the transform Matrix that is used to calculate the component's layout size and position relative to its siblings.

The matrix is typically defined by the component's 2D properties such as x, y, rotation, scaleX, scaleY, transformX, and transformY. Some components may have additional transform properties that are applied on top of the layout matrix to determine the final, computed matrix. For example UIComponent defines the offsets.

Note that layout Matrix is factored in the getPreferredSize(), getMinSize(), getMaxSize(), getLayoutSize() methods when computed in parent coordinates as well as in getLayoutPosition() in both parent and child coordinates. Layouts that calculate the transform matrix explicitly typically call this method and work with sizes in child coordinates. Layouts calling this method pass false to invalidateLayout so that a subsequent layout pass is not triggered.

Parameters

This matrix is typically defined by the component's transform properties such as x, y, z, rotationX, rotationY, rotationZ, scaleX, scaleY, scaleZ, transformX, and transformY. Some components may have additional transform properties that are applied on top of the layout matrix to determine the final, computed matrix. For example UIComponent defines the offsets property.

Note that layout Matrix3D is factored in the getPreferredSize(), getMinSize(), getMaxSize(), getLayoutSize() when computed in parent coordinates as well as in getLayoutPosition() in both parent and child coordinates. Layouts that calculate the transform matrix explicitly typically call this method and work with sizes in child coordinates. Layouts calling this method pass false to invalidateLayout so that a subsequent layout pass is not triggered.
