I want to create ComboBox tool tips that show up over the drop down list items. The only way I can find to do that is to do dataTips. But I don't like how they cover up the list text. Here is an example that shows how to add dataTips: http://kanuwadhwa.wordpress.com/2007/09/20/add-tooltip-in-listcombobox-control/
Is there a way I can move them over to the side like tool tips? I know I can do tool tips in the ComboBox control if the list items are truncated (in a custom item renderer Label). I have tried adding event mouseOver, mouseOut listeners to the ComboBox.dropDown in the ComboBox creationComplete, but my listeners don't get called. Any ideas?
