[Pharo-users] Spec with dynamic tabs

April 2, 2015

      Hi to all,

I'm working with Spec and appreciate the modularity a lot.
However, I had some difficulties to discover, how I can have a dynamic 
widget in a tab.

Plugging together the TabsExample and the DynamicWidgetChange didn't 
work either.

In the end I discovered the flaw:

- In DynamicWidgetChange>>change the last line from "self openWithSpec"  
to  "self buildWithSpec"  .
   The DynamicWidgetChange example works as before.

But now also the following works (I propose to enhance the example):
- Add a method
   "dynamicTab
       | tab |
       tab := self newTab.
       tab
           label: 'Dynamic';
           icon: Smalltalk ui icons nautilusIcon;
           model: (DynamicWidgetChange  new).
       ^ tab "
   to DynamicWidgetChange.
- add a line "addTab: self dynamicTab " to 
DynamicWidgetChange>>populateManager

Now you can dynamically change the widgets in the fourth tab.

Cheers, Hartmut
