Property Detail

baseline

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".

The default value is null.

setLayoutBoundsSize

()method 
public function setLayoutBoundsSize(width:Number, height:Number, postLayoutTransform:Boolean = true):void

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

Sets the layout size of the element. This is the size that the element uses to draw on screen.

If the width and/or height parameters are left unspecified (NaN), Flex sets the element's layout size to its preferred width and/or preferred height.

Note that calls to the setLayoutBoundSize() method can affect the layout position, so call setLayoutBoundPosition() after calling setLayoutBoundSize().

Parameters

width:Number — The element's layout width.
 
height:Number — The element's layout height.
 
postLayoutTransform:Boolean (default = true) — When postLayoutTransform is true, the specified sizes are those of the element's bounding box. Bounding box is in element's parent coordinate space and is calculated from the element's layout size, layout position and layout transform matrix.

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

value:Matrix — The matrix.
 
invalidateLayout:Booleantrue to cause theparetn container to re-layout its children.You typically pass true to invalidateLayout.
