Well, the main reason I wouldn't want to write my own itemRenderer is that AdvancedDataGridGroupItemRenderer does a lot of stuff I wouldn't want to have to reinvent. It also interacts with stuff like iconFunction that would be annoying to re-implement. Plus, there's the fact that there's a high likelihood that what I wrote would be much less efficient.
But good news! I found a simple way to achieve what I want: <?xml version="1.0" encoding="utf-8"?> <Application xmlns="http://www.adobe.com/2006/mxml"; > <Script> <![CDATA[ // put any icon you want in the embed below, doesn't matter [Bindable] [Embed(source="imageA.png")] private var imgClass:Class; private function geticon(item:Object):Class { return imgClass; } ]]> </Script> <AdvancedDataGrid iconFunction="geticon" itemClick="trace('itemclick')" click="trace('gridclick')"> <groupItemRenderer> <Component> <AdvancedDataGridGroupItemRenderer mouseEnabled="true"/> </Component> </groupItemRenderer> <dataProvider> <HierarchicalData childrenField="subitems" source="{[{label:'test'}, {label:'test2'}]}"/> </dataProvider> <columns> <AdvancedDataGridColumn dataField="label"/> </columns> </AdvancedDataGrid> </Application> The key was setting mouseEnabled=true. It is set to false in the constructor for ADGGIR. I'm not sure why, and I am a little worried that I may be messing up something important. So far I haven't noticed any odd behavior. But if anyone knows a good reason WHY mouseEnabled is set this way, please followup.
