Custom Datagrid Cellrenderer NOT firing datagrid edit events

programming flash
1

Custom CellRenderer issue, using Flash DataGrid in Using FlashPro CS6.

Bottom line:

Can’t get a Datagrid MyCustomRenderer extends UIComponent to pick up skins;
or a MyCustomRenderer extends CellRenderer to fire
DataGridEvent.ITEM_EDIT_BEGIN or DataGridEvent.ITEM_EDIT_BEGINNING.

I am looking for one or the other, to do both.

(My preference would be extending CellRenderer).

Platform:

. FlashPro CS6 . Flash DataGrid component . All code in AS3 class files.

How I got here

import fl.controls.listClasses.CellRenderer;
import fl.controls.listClasses.ICellRenderer;
import fl.controls.listClasses.ListData;
import flash.events.Event;
import fl.events.DataGridEvent;
import flash.events.MouseEvent;
import flash.text.TextFormat;
import flash.text.TextFormatAlign;
import flash.display.Sprite;

// The grid is set to be editable.

public class MyRenderer extends CellRenderer implements ICellRenderer

     // NEITHER OF THESE FIRE -- but the Up/Over/etc skinning is fine.

    addEventListener(DataGridEvent.ITEM_EDIT_BEGIN, function()
        { trace (" [inside the cellrender] " +                      
                 "MyRenderer:DataGridEvent.ITEM_EDIT_BEGIN"); } );

    addEventListener(DataGridEvent.ITEM_EDIT_BEGINNING, function()
        { trace (" [inside the cellrender] " +                      
                 "MyRenderer:DataGridEvent.ITEM_EDIT_BEGINNING"); } );

    public class MyRenderer extends UIComponent implements ICellRenderer {

    // THESE DO FIRE -- but the Up/Over/etc skinning does not work.

    addEventListener(DataGridEvent.ITEM_EDIT_BEGIN, function()
        { trace (" [inside the cellrender] " +                      
                 "MyRenderer:DataGridEvent.ITEM_EDIT_BEGIN"); } );

    addEventListener(DataGridEvent.ITEM_EDIT_BEGINNING, function()
        { trace (" [inside the cellrender] " +                      
                 "MyRenderer:DataGridEvent.ITEM_EDIT_BEGINNING"); } );

I would love an AS3 example where a customRenderer extending Either UIComponent or CellRenderer does both skinning and fires the datagrid events.

Thank you!
