More generally, application developers should assume that Flex "owns" the name property of all DisplayObjects and not use them for your own purposes.

I wouldn't have asked if it didn't matter. The renderer's name property is used in a lookup table in itemRenderToIndices, so by changing it we can't find it. So, you cannot change the name property of a renderer. There are several ways to know which renderer is rolled over. The simplest is to check the type of the renderer. Hopefully you have two different subclasses, one for the guage, and another for the line chart so the test is simple: private function itemRollOverEvent(event:Object):void { if(ListEvent(event).itemRenderer is GaugeRenderer) { ... } else if(ListEvent(event).itemRenderer is LineChartRenderer) { ... } } -Alex ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of arpan srivastava Sent: Thursday, December 14, 2006 12:23 AM To: [email protected] Subject: Re: [flexcomponents] ListEvent.ITEM_ROLL_OVER event not firing in datagrid ? yes I am changing the name property because i have one more column where i have drawn a line chart, so to know which cell my mouse is on , iam testing it like this, private function itemRollOverEvent(event:Object):void { if(ListEvent(event).itemRenderer.name=="myRenderer1") { ... } else if(ListEvent(event).itemRenderer.name=="myRenderer2") { ... } } but I think it is not because of this, as this event is not even fired. ----- Original Message ---- From: Alex Harui <[EMAIL PROTECTED]> To: [email protected] Sent: Thursday, December 14, 2006 9:36:30 AM Subject: RE: [flexcomponents] ListEvent.ITEM_ROLL_OVER event not firing in datagrid ?

Hi Gordon, I never get this event when I roll over renderers in this column. What i found is that when I click on this column, error is thrown. when I debugged this error it was coming from mouseUpHandler( ) of DataGrid.as at this point : var pos:Point = itemRendererToIndic es(r); here I found that pos is null because itemRendererToIndic es() function is not able to find the itemrenderer for this point. ----- Original Message ---- From: Gordon Smith <[EMAIL PROTECTED] com> To: flexcomponents@ yahoogroups. com Sent: Thursday, December 14, 2006 6:30:07 AM Subject: RE: [flexcomponents] ListEvent.ITEM_ ROLL_OVER event not firing in datagrid ? Is the problem that you NEVER get this event when you roll over renderers in this column? Or is the problem that you have to roll over the part of the renderer where you've drawn the gauge? - Gordon ________________________________ From: flexcomponents@ yahoogroups. com [mailto:flexcompone [EMAIL PROTECTED] com] On Behalf Of Alex Harui Sent: Wednesday, December 13, 2006 11:11 AM To: flexcomponents@ yahoogroups. com Subject: RE: [flexcomponents] ListEvent.ITEM_ ROLL_OVER event not firing in datagrid ? Unclear based on your description. What does the code for your renderer look like? ________________________________ From: flexcomponents@ yahoogroups. com [mailto:flexcompone [EMAIL PROTECTED] com] On Behalf Of arpan srivastava Sent: Wednesday, December 13, 2006 6:31 AM To: Flex Components Subject: [flexcomponents] ListEvent.ITEM_ ROLL_OVER event not firing in datagrid ? Hi, I am creating a datagrid in which one column contains a gauge for which i created a renderer and i am drawing rectangles using graphics for creating gauge. I have created a ITEM_ROLL_OVER event for that datagrid, but when i roll my mouse over gauge column, event is not fired. I am not getting why ? ________________________________ Check out the all-new Yahoo!
