I think the widget to look at is TreeModel :) Do you have an image showing what you would like?

Spec question

by Glenn CavarlÃ©

Hi all, i'm new (first post) and my english is very poor so please don't blame me :). I would like to use Spec for display a collection of domain objects and i would like to specify the layout which apply to each items, not just display a String or a Text like "ListModel>>displayBlock:" but a more complexe layout with rows, columns and images within (for example). To illustrate, an equivalent would be the component ListView in Android. I turn to you to know if it's possible to do that with Spec.

Have a look at my old JOOP paper on message passing control - you can have anonymous subclasses where you compile some methods+ changeclass. Stef On 04 Feb 2014, at 19:30, Sean P.
