Default ListField - selectedIndexChange event

Please Login to Remove!

Is there such a thing? So far the only way I can figure to be notified when the selected index of a ListField changes is through the drawListRow.

I've search everywhere but can't seem to find any examples of a callback for that purpose.

Thanks for any help

You can override moveFocus. Check the selected item before the call to super then the selected item after. If different, you've got it. Additionally you could just override moveFocus with the x and y arguments and use those to determine your movement but I've found it unreliable in some circumstances.

Funny you should mention a workaround, I did this in the drawListRow and it seems to work.
Code:
// Until I find a better way, this is how I get a single listchange event.
            iValue = list.getSelectedIndex();
            if(iValue != iSelIndex)
            {
                iSelIndex=iValue;
                cfm.ChangeContent(menu[iSelIndex]);
            }
I'll have to try it in moveFocus as I'm guessing it doesn't get called as much as drawListRow.

Thanks
