[Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

Well that’s actually much easier. :-) What you need to do is to use the presentationClass:startOn: API method.

| ui |
ui := GlamourPresentationModel new.
ui presentationClass: GTPlayground startOn: (GTPlayPage new saveContent: '42').
ui openWithSpec

I just realized that this was not clear from the examples in the class comment. I have updated the class comment to reflect this.

I hope this resolves all your issues!

How can I made this GTPlayPage one that is embedded in a spec glamour interface, like the one in the minimalist example: a dictionary with two keys/values: one which is shown as text and other that is shown as a playground, both populated with the content in the dict values and both, embedded in a widget instead of on separate windows. Is this possible with the current Spec-Glamour implementation?, if not how can be it extended to make this happen?
