Tree Control with two types of branches

I need a tree control that can display two different types of branches with two different + and - icons. In the attached image you can see a snapshot from 3dsmax scene tree. This tree shows the hierarchy of Geometry Objects and Materials. Geometry Objects are organized hierarchicaly where a node can have children. Also, this Geometry Objects can have materials apply, and these materials can have sub-materials and sub-textures that can create more powerful materials. What I need is a tree with this similar capabilities using two different types of +/- icons: [+] and [-] (+ and - inside a box) These icons are used to expand/collapse geometry objects. (+) and (-) (+ and - inside a circle) These icons are used to expand/collapse materials. For this tree I also need a couple of methods that can tell the tree if to display or not geometry objects or materials. So if no materials are displayed, only the geometry objects are displayed (starting from a single geometry object called scene) If the geometry objects are not displayed, then only the materials are displayed and since they don't have a 'link' to the beginning of the tree there can be many first level materials. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
