Represents a window that displays a hierachy list of items. Examples of such hierachies can be the headings in a document, the entries in a index, or the files and directories on a disk.
Use TfpgTreeView to add an expanding and contracting outline to a form. Each node in a tree view control consists of a label and a number of optional bitmapped images. Each node can have a list of subnodes associated with it. By clicking on a node, the user can expand or collapse the associated list of subnodes.
| Remark: | There is basic column support, but this is still very experimental. |
