GTInspector: add view tab for custom object

by Mark Rizun

Hi everyone, I would like to extend GTInspector for custom object - add a roassal view tab. I found this kind of code to do this: gtInspectorViewIn: composite <gtInspectorPresentationOrder: 40> composite roassal2 title: 'View'; painting: [ :view | self viewOn: view ] The problem is, that I want to use a view that I already have, but not the one which is passed as an argument to block [ :view | self viewOn: view ]. It should be simple. Am I missing something?

They break encapsulation, they cloud the object interface, and most importantly they allow bugs to be introduced by undocumented modification of the object's internal state. Nobody has shown me a good reason for their existence and I never use them except where I'm forced to use them in Spec and Glorp. Craig PS: I'm forced to use them in C# as well (my day job). Because in C# it's only way to promote a local variable to a property which is required by most frameworks.

Hello, I think It was only to show how to use Rubric for text editing.
