My thoughts exactly! 😊 There is a description on how to do this i the spec book, here https://ci.inria.fr/pharo-contribution/view/Books/job/BuildingUIWithSpec/lastSuccessfulBuild/artifact/book-result/SpecBooklet.pdf#section*.20

Subject: [Moose-dev] Re: Error dialog?

Hi Luke,

For example, I would like to show an error message that includes the output of a Unix command (potentially quite long.)

I had similar issue and in the end I decided to just create a custom dialog using Spec.

tm := TextModel new.

tm title: 'Failed to do something useful'.

tm enabled: false.

tm text: 'A ' asText, ('lot' asText allItalic), ' of ' asText, ('text' asText allBold makeAllColor: Color red), ' can fit into this box.' asText.

tm openDialogWithSpec

 Obviously this is literally the most basic way, I could e.g. compose multiple Spec Models etc.
