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)
{
...
}
}

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.

Are you changing the name property of the renderer?

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.

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?

Unclear based on your description. What does the code for your renderer
look like?

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 ?
