Could you send me some sample code that demonstrates the problem? The
first approach that you mentioned is the right idea, although there may
be some piece missing in the bridge from FOX to FXRuby.
The second example definitely wouldn't work, because FXScrollArea
doesn't forward those messages to its message target, and that's what
connect() is all about: setting up a map the messages that a widget
sends to its message target, and some chunk of code to handle that
