=============
The Button package defines functions for inserting and manipulating
“buttons” that can be activated with the mouse or via keyboard commands.
These buttons are typically used for various kinds of hyperlinks.
A button is essentially a set of text or overlay properties, attached
to a stretch of text in a buffer. These properties are called “button
properties”. One of these properties, the “action property”, specifies
a function which is called when the user invokes the button using the
keyboard or the mouse. The action function may examine the button and
use its other properties as desired.
In some ways, the Button package duplicates the functionality in the
Widget package. Introduction (widget)Top. The advantage of the
Button package is that it is faster, smaller, and simpler to program.
From the point of view of the user, the interfaces produced by the two
packages are very similar.
