Updates: Cc: guillermopolito marcus.denker stephane.ducasse Comment #1 on issue 3583 by tudor.gi...@gmail.com: Shout should only be active in code panes http://code.google.com/p/pharo/issues/detail?id=3583 From Guillermo: Why not delegate it in the used Editor ? SmalltalkEditor should use shout while the other editors should use the NullTextStyler. Maybe something like this: PluggableTextMorph>>useDefaultStyler self styler: textMorph editor styler Or better: PluggableTextMorph>>useDefaultStyler self styler: textMorph styler And then Editor>>styler ^NullTextStyler new SmalltalkEditor>>styler ^... ... Anyways, I'm looking that PluggableTextMorph>>textMorphClass "Answer the class used to create the receiver's textMorph" ^TextMorphForEditView and TextMorphForEditView>>editorClass ^ SmalltalkEditor So it's what I suggested needs a lot of work more...
