[ruby-talk:12593] FXRuby question

Hello,

I'm having trouble getting the following to work.  For some
reason, the FXTextField doesn't want to take input.  Can anyone
help?  Even better, can anyone point me to some documentation
which describes how different Widgets are used?  The FOX
documentation seems very high-level and not useful to a
quick-hack programmer, and the examples aren't inclusive enough.

Thanks,

Jimmy
