Hi list,
contains Magritte the functionality to define options with different values
and labels
via MASingleOptionDescription? Like:
#('de' => 'Germany' 'gb' => 'Great Britain' )
salute

Hi Thomas,
2007/4/12, Thomas Fischer <th.-fischer(a)web.de>de>:
contains Magritte the functionality to define options
with different values
and labels
via MASingleOptionDescription? Like:
#('de' => 'Germany' 'gb' => 'Great Britain' )
this were not easily possible. In fact, the reference of your
description was converting the object to a string.
Now, I've just add #labelBlock: which will help you do that kind of thing:
(MASingleOptionDescription auto: 'country' label: 'Country' priority:
1)
reference: MANumberDescription new;
options: {1. 2. 3. 4};
default: 1;
labelBlock: [:value :reference | (value + 10) printString];
beRequired;
yourself
Here, elements are 1, 2, 3 or 4 and they are printed 11, 12, 13, 14.
To solve your problem, you may want to use a dictionary:
| dict |
dict := Dictionary new
at: 'de' put: 'Germany';
at: 'gb' put: 'Great Britain';
yourself.
^ (MASingleOptionDescription auto: 'country' label: 'Country' priority:
1)
reference: MAStringDescription new;
options: dict keys;
default: dict keys anyOne;
labelBlock: [:value :reference | dict at: value];
beRequired;
componentClass: MASelectListComponent ;
yourself
This has been implemented in Magritte-Model-dc.253 and Magritte-Seaside-dc.218.
Lukas: I will now comment the changes

Lukas told me is never a good idea to add blocks to descriptions. So,
you may prefer not to use that solution. I'm trying to implement
another idea from Lukas. Please wait.

Hi again,
Lukas and I solved the problem. You must use the last version and do
something like:
descriptionCountry
^ (MASingleOptionDescription auto: 'country' label: 'Country')
optionsAndLabels: {#fr->'France'. #gb->'Great Britain'};
default: #fr;
beRequired;
yourself
This work with multiple option descriptions too:
descriptionCountry
^ (MAMultipleOptionDescription auto: 'country' label: 'Country')
optionsAndLabels: {#fr->'France'. #gb->'Great Britain'};
default: {};
beRequired;
yourself

What about more dynamic selectors?
Consider that I have an option selector that is addable - there are a
set set of options, plus the user can add his own. I'll have to do a
database query to come up with the available set of options and it
will vary. How will this work?

Create (or update) your description dynamically on the instance side:
Address>>description
^ super description copy
add: ((MASingleOptionDescription auto: 'country' label: 'Country')
optionsAndLabels: self superComplicatedQuery;
default: #fr;
beRequired;
yourself);
yourself
