No, but you can do whatever you want to do in this method. The important bit is that this method appears to get called when you need to refresh the UI in some way. In particular, I've been using this method to change the appearance of the item renderer when it is selected or deselected, which is what you want, so using this method would work for you, if you were using LabelItemRenderer... > Also, I am using a standard ItemRenderer and not a LabelItemRenderer and > there does not appear to be a drawBackground() method in this class. Is > there a similar method that I can override in a regular ItemRenderer?? I don't know. It looks like you may need to dig into the LabelItemRenderer code and see what events are causing the drawBackground() method to fire. I'd either simply look at LabelItemRenderer's code, or create a simple app that uses LabelItemRenderer, put a breakpoint into drawBackground(), then select the item and look at the stack trace.
