Morph object -- setProperty:toValue:
Last updated at 9:58 am UTC on 2 November 2020
A morph object may carry many properties by using the method



Get an Inspector on a SketchMorph which is on the desktop and evaluate in the code pane

 self setProperty: #isSlide toValue: true.

Another morph object called "PresentationNavigation" may then get all the morph objects on the desktop

 ^(self project world
        submorphsSatisfying: [:m | m hasProperty: #isSlide]).

and present them one after the other thus showing only one at once.
