Thanks Bill.

The "Squeak" way allows double-click just inside the first quote to select the relevant snippet of course though ;-)

Perhaps default models would be a good idea though it can, with over-reliance, tend to distance things from the real model...

Nothing in TEasilyThemed for splitters. Note that Polymorph only fixes issues with SystemWindow splitter usage at present, rather than arbitrary owner morphs.

Given a system window:

win addPaneVSplitterBetween: morph1 and: {morph2}.
main splitters last
color: win paneColor.

Given other morphs (for the moment).

aMorph addPaneVSplitterBetween: morph1 and: {morph2}.
aMorph splitters last
  color: aMorph paneColor;
  addLeftOrTop: morph1;
  addRightOrBottom: morph2.

Regards, Gary

Subject: [Pharo-project] Polymorph observations

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
