Problem

While styling my application, I wanted the color of each row of my AdvancedDataGrid to change when rolled over, but I didn't want the same effect for the headers, which happens by default.

Solution

I override the mouseOverHandler function for AdvancedDataGrid to not run if the item being rolled over was a header item.

Detailed explanation

Line 12 of source file NoHeaderRolloverADG.mxml makes use of the AdvancedDataGrid method isHeaderItemRenderer, which is passed any itemRenderer, and returns a Boolean to say whether the renderer is a header renderer or not. If it is a header renderer the method is exited, and no further logic is run, otherwise, the default handler is called.
