Miller Columns / Cascading Lists control
« on: December 26, 2020, 08:38:42 pm »
Has anyone implemented a component for showing data (trees) in Miller Columns?

It is common in mobile apps (though, there you typically only see one "column/level" at a time) and historically in some file browsers (like on macOS) or in Smalltalk.

FWIW, I became a fan of this visualization technique after reading the papers: Applying mSpace interfaces to the Semantic Web (though I don't do anything "semantic web" related),  The Evolving mSpace Platform, and A Comparison of Hyperstructures: Zzstructures, mSpaces, and Polyarchies.
The authors of these papers also created a (now-defunct) demo at https://mspace.fm but you can see screenshots of the UI in the aforementioned papers.

Googling, I could find one commercial solution that is Delphi/Pascal compatible but it doesn't work for me ($$, Windows).

I can cobble something together for my use case but thought I'd first check in case someone has already done the work.

The visual appearance reminded me immediately of Smalltalk... where it is, of course, much more than a /file/ browser.

Me from Windowmaker, but that is of course a NextStep derivate.  To be honest, I didn't find them very useful, but maybe they were too primitive.

As an aside, I've just come across https://github.com/PierceNg/pharo-vm-embedded-pascal for embedding a Smalltalk implementation in a Pascal program. I've not yet attempted to investigate to what extent the languages can interact.

Hi!

AFAIR there was an implementation in Delphi 1.

They abolished a lot of "toy" stuff in Delphi 2 like the
"speedometer gauge" and perhaps also the Miller Columns.
