Dear Squeak fondation,
I am actually working on the SlideMorph project
What is the SlideMorph project?
Who else is doing it?
and my purpose is to custom the application in order to have the possibility to hide a slide.
I have been working on a similar type project. My goal was to implement more fully the Gif98A spec.
What I found was that I needed a morph to emulate the gifs virtual screen and to control the display of the individual images. What I wound up with was a variant of image morph that had a #step method which waited for a timer to time out then hid a submorph and showed the next. The hiding and showing I encapsulated in a #singleStep method so that I could also choose to manually (via menu command) go from one morph to the other.
So for your purposes you would need each slide to be a morph. Embed all the morphs into the virtual screen morph which would be either transparent or a background color. The create the singlestep and step methods.
All morphs respond to #hide and #show. All objects respond to #stepTime. I used the steptime of each submorph to determine how long between singleSteps.
Hth,
Yours in curiosity and service, --Jerome Peace
