hierarchical lists with collapsing arrows

[Marielle Lange]

Dear Xeubie,

Why not simply reuse the code of the ontology manager in the open  
gallery? Basically, you send an xml tree where the expanded nodes are  
represented with + and the unexpanded ones represented with - and  
this gets represented as a tree. You  can click on any arrow and it  
will change of shape. I use symbol fonts on the mac to display the  
arrows, but it shouldn't be too difficult to change the script to use  
an image (set the imageSource of char 1 of line x of tTreeObject to y)

Go to:
http://revolution.widged.com/stacks/?category=tools_plugins
Download the "ontology manager" (which proposes better written code  
and better commented code than the treeview one)

Or directly to:
http://revolution.widged.com/stacks/open/tools_plugins/ 
ontology_manager.rev.zip

Best,
Marielle
