Well, with the refactoring Stef and I did at CampSmalltalk, blocks (as an
action) are now supported for buttons.
I'll have to add some helpers (or make the existing ones agnostic) to
TEasilyThemed for convenience though.

Ask away if you'd like more examples of Morphic/Polymorph things...
I think everybody want to have (lot) more examples ;)
More seriously, on Pharocasts the GUI tab is the most clicked one by far
(according to google analytics), so I suppose a lot of people want (including
me) to start by doing a little graphical app. Polymorph seems cool, but
aaarggghhh almost no documentation. Indeed I'm just starting to feel the logic
behind it so I will try to record more screencasts on it.
Even for me, that was the first time I used a Block as the model for a
button! :-)
And I think that's how it should be for all callbacks: it's far easier to
think (for me at least) and design by giving a block to an action than a
selector and a model.
Laurent (who is waiting for more examples :)

This example is really interesting, I've just learn a lot of things.
