| 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.

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,

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 the invalidateLayout() method so that a subsequent layout pass is not
triggered.
Parameters
value:Matrix — The matrix.

invalidateLayout:Boolean — true to cause the parent container
to re-layout its children. You typically pass true
to the invalidateLayout() method.
