File explorer
The example of Windows Explorer shows how easily can a grid be used for treelist view. It is a component with a single header that enables use of objects of different type on the same hierarchy level or on different hierarchy levels.
Hierarchy building in the grid is well optimized. New files and folders are added only upon expansion of the parent node saving memory and CPU resources. Folders that contain files and subfolders are marked with (+) icon that can be used to expand them.
