hi, is there something like a tree-panel available for use with mcclim? i saw that there is a class named tree-with-cross-edges in the experimental subfolder of the mcclim directory tree, but it doesnt seem to be useful (by now).
kind regards, alex

I don't think that's what you want. The tree with cross-edges was developed for graph layouts where the graph is "mostly" a tree, but with cross-edges in some places. More precisely, it was developed for HTN plans, if that helps --- these are task decomposition trees (top level task is most abstract, lower levels are increasingly concrete) which have cross edges for temporal constraints. So you get things like
A decomposes into (has for children) B and C.
There is an additional edge from B to C to indicate that B must be performed before C.
If you are looking for something like that standard "tree of folders" widget that is so common in modern UIs, tree-with-cross-edges is not it.
You are right, BTW, that the t-w-c-e has not been maintained (at least not by me).
best, r
