Athena Widgets
The Athena widgets were written at MIT. Each of the widget names is a
hypertext link to a page describing the widget and including an example.

to take place. This widget can display a multi-line string or a bitmap image.

place.
- Label
- A rectangle that may contain one or more lines of text or a bitmap image.
- List

individually selected. When an element is selected an action may take place.
- Panner

dimensions. Notification of movement may be continuous or discrete.
- Repeater
- A push button that triggers an action at an increasing rate when selected.
- Scrollbar

dimension, may cause a specific action to take place. The Scrollbar may
be oriented horixontall or vertically.

area with a settable mouse cursor and special border.
- StripChart

may also be used as radio buttons to implement a "one of many" group of

Text Widgets

Composite and Constraint Widgets
- Box
- This widget will pack its children as tightly as possible in
non-overlapping rows.
- Dialog
- An implementation of a commonly used interaction semantic to
prompt for auxiliary input from the user, such as a filename.
- Form
- A more sophisticated layout widget that allows the children to specify
their positions relative to the other children, or to the edges of the form.
- Paned
- Allows children to be tiled vertically or horizontally. Controls are also
provided to allow the user to dynamically resize the individual panes.
- Porthole
- Allows viewing of a managed child which is as large as, or larger than its
parent, typically under control of a Panner widget.
- Tree
- Provides geometry management of widgets arranged in a directed, acyclic
graph.
- Viewport
- Consists of a frame, one of two scrollbars, and an inner window. The
inner window can contain all the data that is to be displayed. This inner
window will be clipped by the frame with the scrollbars controlling which
section of the inner window is currently visible.
