So, how do you enact an "Expand All"/"Collapse All" type function on a TreeViewCustomGUI Tree? I haven't found any clues yet...

You have to keep track of the opened/closed status yourself. Implementing an "expand all" should then be trivial; just set all objects to open. C4D will ask you for this in TreeViewFunctions::IsOpened(). (Sorry if any of this is broken. I haven't tried it myself.)

Right, figured that out finally. Took a little consideration of my TreeViewFunctions::Open() method as implemented to realize that all I had to do was to SetBit() or DelBit() of the 'expand' flag for all of the entries (and the rest is taken care of). One of those cases where I wasn't certain if programmatic action would be taken as well as user action.
