[Pharo-users] Spec layout

[Marion Noirbent]

Hi,
I'm trying to create a widget whith Spec, managing a collection of 
RadioButton. But I have a problem with defaultSpec (the accessor of the 
collection is the methods "buttons") :

If i put defaultSpec on class side, i can't acces the collection of the 
instance. (the following code iterate on the string)

defaultSpec
        <spec: #default>
        ^ SpecLayout composed
                newColumn: [ :column | #buttons do: [ :item | column add: item 
] ];
                yourself

If i put it on instance side, the lookup don't find it (in the book 
Building UI with Spec, it said the lookup begin by the instance side and 
it allow to have specific UI, in part about layout)

defaultSpec
        <spec: #default>
        ^ SpecLayout composed
                newColumn: [ :column | self buttons do: [ :item | column add: 
item ] ];
                yourself

Any idea ?
