Headed List Box – Row Hight ??

Is there a way to find out what the Row Height is of a Headed List box?

I assume it is based on Font Size and the $linehextra property.

I am working with a resizable window and sometimes the list is in a state so
that if you click the last visible line in the list it scrolls that line up
and selects the next line. This happens when you the last visible line is
one pixel more than the size of the list object.

I am looking for a way to measure the row height so that I can size the list
object to avoid this issue.

This needs to be done at runtime because the library can use Window Scaling
which means the values change from design time.
