Hah! no, not quite that unlucky, although i do 'fondly' remember

I understand that this is probably the way that is simpliest
however I also believe that reductionism is 'good'. It is
preferable in my eyes not to have the same code repeated
multiple times in different classes, when it should (in my eyes)
belong in the 'parent' class. 

Imagine this example:

class Funky < FXDialogBox
   def initialize 
      accept=FXButton.new(buttons, "&Accept", nil, self, ID_ACCEPT,
      FRAME_RAISED|FRAME_THICK|LAYOUT_RIGHT|LAYOUT_CENTER_Y)
   end
end

class Mojo < FXMainWindow
    def initialize 
         @lp_dialog=Funky.new(self)
    end
end

now, from inside the Mojo class, how would I go about tying the
connect on the accept to a procedure/method or callback ?


I know it may sound crazy, but if i can do one line such as 
'(FXButton)@lp_dialog.accept.connect(SEL_METHOD... etc)
surely that has to be better than the 20 or 23 or so lines that
I need to do to create my 'Funky' dialog in the other classes ?

Thanks for the pointers (no pun intended) though, most helpful
and glad to see that there is a 'live community' that I can learn
and support. Lack of arrogance also seems to be a 'Fox Community'
strongpoint (unlike certain other Toolkits developers :D

regards and thanks
