+1 for registerable frameworks... hopefully not mutually exclusive "window-to-window" (think, one "window" being Ffenestri, another Morphic, another Morphic 3.0...). Gary

Hi guys
Here is the summary of the discussion we got with mike today.
In the context of the ESUG sponsored effort mike and john will work on making the - VM sleeping correctly, - using a semaphore do avoid event polling and all the rest related to that. - fixing the event handling.
Now the point is that mike will not change Morph, just clean what is needed so that the event system and the polling gets cleaned. The idea is that Morph cannot be cleaned.
In parallel mike has been working on ySqueak and in this context he worked on a new morphic model.
Now we should learn from squeak and make sure that we have an infrastructure that allows one to plug difference UI frameworks (no "Smalltalk isMorphic" in the future). In addition we want to make sure: - that we can plug different UIFrameworks (Miro, Morphic30, YSqueak or something else) - kernel class do not depend on UI.
So mike based on his sophie experience designed a new event model based on Announcement which support well multiple input devices, different platform key, different windowing bindings for future native support.
So the idea is the following: - let make Morphic smaller and cleaner but acknowledge that Morphic is not the long term future. - mike will produce a new event model, that the other UI frameworks could use and extend. He will ask fro feedback. - Agree that we use announcement as an infrastructural foundation. - make sure (with your help and feedback) that we can plug another UI framework (in particular in the event loop handler should support a registration mechanism. - It would be nice to see how miro can use the new event model and be plug in pharo as well as the ySqueak new model.
I would like to lower the frustration of people. The point is not to chose a framework against another one but to make sure that we can load and plug different frameworks.
So please comment.
Stef
