[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [53355] trunk/blender: This commit frees list ui items from their dependencies to Panel, and hence from all the limitations this implied (mostly, the " only one list per panel" one).

[Bastien Montagne]

Nah, that page is for history now :)

UI_UL_list is just a py wrapper around default template_list (i.e. the 
one displaying icon+name of the items). If you want more, you can either 
re-use one of the already defined UIList classes (in UI code, like e.g. 
MESH_UL_vgroups for vertex groups…), or create your own (using 
bpy.types.UIList as base).

All in all, lists are now handled pretty much like panels or menus! 
Again, having a look at ui code of properties_data_mesh & co should make 
things easy to grasp! ;)
