There is no public API for that. You can get to it from subclasses, but how depends on which version of Flex. Another way would be to use a custom ClassFactory.
2.x it is listItems[0][i] 3.0 it is header.headerItems[i] ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Bradley Sent: Thursday, January 17, 2008 11:52 AM To: [email protected] Subject: Re: [flexcoders] Re: DataGridColumn headerRenderer instance That is a great idea I can use for the height and width. However, I still need the x and y. I can probably infer the y from the datagrid y, but then I need a replacement to get the x. I am currently doing this: var xOffset:int = 0; var horizScroll:int = grid.horizontalScrollPosition; for each ( var col:Dat! aGridColumn in grid.columns ) { if ( horizScroll == 0 ) break; xOffset += col.width; horizScroll--; } var xPos:int = headerRenderer.x - xOffset; As you see, I am using the headerRenderer instance (which I only have when I have a mouse event to get it out of) to determine the x position. I've got three of the four I need! Any ideas on a different way to get x?
