Project: Locus
Class: Folder
Description:
Folder is a subclass if List, and its function is simply to manage that groups that it contains, and to provide the means to display them. The displaying is done through the use of the FolderViewer class, which displays the group that is currently selected in its browser. The Folder keeps track of the size and location of the screen, and the selected group so that these attributes will be restored when the Folder is opened again.
