>> Ciao Community!
>> As someone said (JeanMarc) this is a real community, made not only
>> by email
>> addresses, but also by brains, ideas, friendship, and (when in
>> EurOmnis) by
>> hands, bier glasses, smiles and fun.
>> For this reason I want first to wish you all, but expecially the
>> EurOmnis
>> fellow, a great 2010!
>>
>> Let's go further, and discuss about some OO concepts.
>> During these months (since EurOmnis) I did not code a single line  
>> with
>> Studio, mainly for two reasons:
>> The first is that my Hotel was full and a lot of work to do. Even
>> after
>> Christmas holidays I have a quite busy day to deal with..
>> The second is that I'm still dealing with the "damned" paradigm
>> shift, so I
>> read, study, and read again the books suggested in this list.
>>
>> Ideas are coming more clear now, but a "concept" about OO is not
>> immediately
>> understandable:
>> Let me make an example with Omnis Studio:
>>
>> For a group of windows classes, the code in $construct (and some  
>> other
>> "general" methods) became blue code.. (Hey Doug, I've got it!!)
>> Then I realized that NOT ONLY methods, but also buttons and lists
>> could be
>> more "general". Great, I said..
>> I can code a button to be "polymorphic", pass to it some parameters
>> and use
>> its blue code without worring about..
>> Now my need is to inherit the methods behind a parent list, but also
>> change
>> the appearance of the list, or the position of a button inside the
>> subwindow.
>> If everything works great in a parent windows with buttons and one
>> list,
>> what could I do to have this list wider, or to add a field (column)
>> in it,
>> or to have my button in a different position?
>> What if a window have to display my customers list and behave always
>> in the
>> same way (methods) but the data have to be displayed in a different
>> way?
>> Please don't tell me I have to redraw it assigning every property
>> via $cinst
>> commands (maybe with a ton parameters to change on-the-fly obj
>> properties in
>> the instance).
>> Oh well, you could say it.. if it is the only available practice!
>> My answer would be: cut the buttons (or Window objs) you want to
>> change, and
>> paste them in the subwindow. You'll have to check every button in
>> every
>> child window, and you'll never be able to inherit the methods you
>> wanted to
>> be executed.
>>
>> Please guys: I just want to know if I'm approaching the right
>> runway, or if
>> I'm landing over a forest. In other words: should I reset and start
>> to read
>> again from 101 my Object Oriented literature?
>>
>> Finally a wish for the 2010:
>> Fred, a specific 101 OO course for the next EurOmnis would be greatly
>> appreciated.
>> I have some names to suggest you...
>>
>> Cheers
>> Franco
