You need to call create() on widgets that you add after the program's 
running, e.g.

     aNewList = FXList.new(parentFrame, ...)
     aNewList.create

Yes, that was me lying. I mean distorting reality.

The code for FXListItem isn't written in Ruby, and this is true for 
almost all of FXRuby. FXRuby is a wrapper around the FOX library, which 
is C++ code. The (fake) Ruby code that I showed for FXListItem#getHeight 
is a "translation" of the corresponding C++ function into Ruby.
