Is there a callback that gets called whenever a node is expanded or collapsed in a tree view? I haven't found one but I'm notorious for not seeing the forest for the trees... :) I tried with an :AFTER method for TREE-VIEW-UPDATE-AN-ITEM, but I saw the effects that I wanted "one step too late," so to say. Is that function called reliably whenever something is collapsed/expanded? Maybe I was just missing an APPLY-IN-PANE-PROCESS or somesuch. Thanks, Edi.
How about :checkbox-change-callback initarg? Wade Edi Weitz wrote: > Is there a callback that gets called whenever a node is expanded or > collapsed in a tree view?

Maybe a :BEFORE method for TREE-VIEW-UPDATE-AN-ITEM? (if it is one step too late). Or subclass tree-view and write your own method for the previous. I am a little fuzzy on what you really what. Do you want full control over whether something is expanded/collapsed, or just be informed of its status?
