Vertical height needed for no scrollbar? [message #453449]

Is there a prefered way to determine the vertical height needed to
display a control without need for a scroll bar (example: get the height
of a Tree control so that the vertical scrollbar does not need to be
displayed).

It looks like computeSize() should do this but it doesn't appear to work
correctly. For a Tree control it only appears to take the root elements
into account when calculating the height and not any open items (and
that is only on Windows, on Gtk and OS X it behaves differently.)

I'm I correct in my assumptions for computeSize()? Is what I'm seeing
in the Tree control a bug?
