Tree View

A tree view or an outline view is a graphical user interface element (widget) that presents a hierarchical view of information. Each item (often called a branch or a node) can have a number of subitems. This is often visualized by indentation in a list.

An item can be expanded to reveal subitems, if any exist, and collapsed to hide subitems.

Tree views are often seen in file manager applications, where they allow the user to navigate the file system directories. They are also used to present hierarchical data, such as an XML document. Extended tree view is the central component of an outliner application.

Famous quotes containing the words tree and/or view:

    As a tree my sin stands
    To darken all lands;
    Death is the fruit it bore.
    Christina Georgina Rossetti (1830–1894)

    War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.
    Susan Sontag (b. 1933)
