Many of the larger scripts in 3dsMax I create nowadays contain the xtraTreeList control which is shipped since 3dsMax 2010. This control is a combination of a treeview and a listview and also contains a whole lot of other editors like checkboxes, comboboxes, buttons, spinners. Every cell in the treelist can contain one or more of these editors which makes it a very versatile control.
This is a render-preset script. All settings can be edited within the treelist. There are comboboxes, spinners for integers and floats, checkboxes and text-fields. Read about this script elsewhere on my blog. This one isn’t public yet…
