LayoutGroup, this component is meant as a base
class for creating a custom item renderer for a DataGrid
component.
Sub-components may be created and added inside initialize().
This is a good place to add event listeners and to set the layout.
The data property may be parsed inside commitData().
Use this function to change properties in your sub-components.
Sub-components may be positioned manually, but a layout may be
provided as well. An AnchorLayout is recommended for fluid
layouts that can automatically adjust positions when the grid resizes.
Create AnchorLayoutData objects to define the constraints.

Don't forget to handle the case where the data is null.
| postLayout | () | method |
protected function postLayout():void
Called after the layout updates the item renderer's children. If any
children are excluded from the layout, you can update them in the
postLayout() function if you need to use the final width
and height in any calculations.
In subclasses, if you create properties that affect the layout,
invalidate using INVALIDATION_FLAG_LAYOUT to trigger a
call to the postLayout() function when the component
validates.
To make changes to the layout before it updates the item
renderer's children, override the preLayout() function
instead.
See also
| preLayout | () | method |
protected function preLayout():void
Makes final changes to the layout before it updates the item
renderer's children. If your layout requires changing the
layoutData property on the item renderer's
sub-components, override the preLayout() function to
make those changes.
In subclasses, if you create properties that affect the layout,
invalidate using INVALIDATION_FLAG_LAYOUT to trigger a
call to the preLayout() function when the component
validates.
The final width and height of the item renderer are not yet known
when this function is called. It is meant mainly for adjusting values
used by fluid layouts, such as constraints or percentages. If you
need io access the final width and height of the item renderer,
override the postLayout() function instead.
