component, consisting of a permanently visible row of button
icons which, when clicked with the
mouse, cause the
program to perform some action such as printing the current
document or changing the
mode of operation.
The tool bar buttons often duplicate functions accessible via
menus but are easier to use since they are permanently
visible. A typical use would be in a
paint program where
the tool bar allows the users to select one of the various
painting "tools" - brush, pencil, bucket etc.
allow the user to customise the functions accessible via
toolbars, in others the choice is fixed by the programmer.
