Not to be unhelpful - but one of the original pleasures of APL is how easy
it is to go through explore-learn-apply processes.  What follows on from
this is that you learn what the writer meant by the words they wrote.

Another road to enlightenment - seriously - is to load up something like VB
(VB2005 seems to be a giveaway these days) and explore the sample code and
help texts in there. Quite often GUI-handling is a transliteration.

It's possible that you want to do things with treeviews that they just
won't do (I've had one or two of these myself - it's not Dyalog's fault,
they're just letting APL programmers use what Microsoft offer).  Maybe you
could give us some specific examples?
