what I did so far was:
I extended the extendItem method in my custom tree adding the following:
if(open)
{
var allChildren:int = getAllChildrenCount(item); // with this function
I
get the amount of new child recently added
if((rowInfo[selectedIndex].y + super.rowHeight + (allChildren *
super.rowHeight)) > listContent.height)
{
trace("need to scroll")
verticalScrollPosition += 22; // Hardcoded number just for
testing
purpose
}
}
it scrolls, but it also change the visibility of other items...
Any clue?
thanks,
Diego.
