- selected directory in a popup FileListView. Thus, directories can be
- selected from the DirectoryTree, and files can be selected or opened
- in the FileListView;
- (b) suports creating, renaming, deleting, copying and moving operations on
- directories;
- (c) calculates the size of a selected portion of the directory-tree.
- (d) connects/disconnects network drives.

- 5. Notes on Usage
- =================
-
- 5.1 Interconnecting components
- ------------------------------
-
- If you use both TLsDirTree21 (or TLsDirTreeCombo28) and TLsFilelistView28
- components in an application, they must be mutually connected through the use
- of the TLsDirTree21's (or TLsDirTreeCombo28's) 'FileList' property and the
- TLsFileListView28's 'DirTree' property (or 'DirTreeCombo' property if
- TLsDirTreeCombo28 is used). Once they are interconnected, changes in one
- component will be automatically reflected in the other component.
-
- For example, the LsDirTree21 and LsFilelistView28 components in your application
- are named as LsDirTree211 and LsFilelistView281 respectively. You can use Object
- Inspector to set LsDirTree211's 'FileList' property to LsFilelistView281;
- likewise, set LsFilelistView281's 'DirTree' property to LsDirTree211.
