1. To tell whether a class is abstract: isAbstract := [ :aClass | (aClass whichSelectorsReferTo: #subclassResponsibility) isNotEmpty or: [ (aClass respondsTo: #isAbstract) and: [ aClass isAbstract ] ] ]
Just be aware that some classes are "abstract", but you can actually instantiate them, because in #new they return something else. isAbstract value: String "true" 2. To change an icon for a single class (and it's children), add a method to class-side named "systemIcon" 3. To conditionally change an icon for all classes 3.a.) override Object>>systemIcon and make a test based on the isAbstract in 1) 3.b.) or do the same, but in AbstractNautilusUI>>#classIconFor: , this is where test icons are added for example Peter On Mon, Apr 4, 2016 at 11:49 AM, Hilaire <hila...@drgeo.eu> wrote: > Hi, > > Can Nautilius indicate when a class is abstract (i.e. at least one > method in the class, then its hierarchy is definted respond > subclassResponsability?) > > I did not find it in the Analyze menu. > > > Thanks > > Hilaire > > -- > Dr. Geo > http://drgeo.eu > > >
