Gary,
I have done a little with Polymorph and am quite impressed. A small usability
suggestion for the examples is to include comments with the text on a line by
itself. It is a lot easier to execute something formatted as
"
ThisOrThat example
ThisOrThat someOtherExample
"
than it is the (very common in Squeak) "GoAhead iChallengeYouToSelectMe
andMissTheQuotes".
On to more substantive things. TEasilyThemed is a big help, but some model
and/or presenter classes would help. Consider a list. One has to define an
aspect for the selection index and initialize it to zero. Similar comments
apply to trees, with the added wrinkle of wrapping the nodes with appropriate
objects.
Dolphin's MVP framework creates default models that can be replaced. One
weakness of the defaults is that they can take significant time to create for
substantial objects. I hacked around that, and we could easily design it out
of anything that we build. Dolphin lists and trees treat their selection in
terms of the object selected rather than the index. One can get and set the
index if needed, but it is not generally as interesting as the object behind
the selection.
One good thing about specifying the aspect is that one can can connect a view
to an aspect of any model. Dolphin allows for the same flexibility via value
adapters and type converters.
Does TEasilyThemed include helpers for creating splitters?
Bill
