select tag population / callback..

hey, guys.. i am trying to figure this out, but i am missing something here:

i have an array of objects...

i would like to populate a select box so that the options will be
populated with the some text from the object..

when the form is submitted, i want the callback to set some value to
the object pointed to by the select box..

if i do something like this:

        html select
                list: self trackSelect;
                callback: [:value | ?? ].

the box populates correctly, but i can't figure out how to grab a
handle to the object selected..

am i just thinking about this all wrong?

thanks!

Look at the senders of #select for ideas on how it can be done.

In a form just make the callback something like

callback:[:value | self setSelectedValue: value]

when i do this, i end up setting the value to the value of the option
tag..  what i need to do is point it to the actual object.. i have a
feeling i am not wording this correctly..

what i'd like to do is populate the select tag options with some text
generated by my objects.

when the form is processed, the value in my component would be set to
the object that the select points to..

i hope i am making sense..

(html select)
    list: self countries;
    selected: country;
    labels: [:ea | ea label];
    callback: [:obj | country := obj].

where #country is an ivar and #countries is a selector returning a collection of your country objects each of which responds to a #label for its textual representation, for example.

Sergio,

You can also implement Country>>renderOn: instead, but #labels: makes more sense generally, because in one list you could be using #shortLabel and in another #longLabel etcetera.

HTH,

There is a lot to review and reassess in TDD; and a lot of value.

thanks!

it's interesting in that i wrote that more than a year ago.. and i
have evolved even more over time.. i have once again thrown over IDEs.
this time, i am using vim for all my non smalltalk things.

believe it or not, i have learned most about the art of software
development through my side adventures with smalltalk..

it has changed the way i have approached OOP in every way..

i feel like in other languages, i am playing with objects at 50,000
feet.. with smalltalk, i feel like the objects are my friends and
neighbors..
