9.1 Creating a toolbar button

To create a toolbar button you can do:

(setf print-button

      (make-instance 'toolbar-button

                     :image :std-print

                     :text "Print Something"

                     :name :print-something))

You should supply image , text and name . This is because the user can customize the toolbar such that one (or all) of these appear, as described in Modifying toolbars.

A toolbar-button cannot be displayed directly. To include it in an interface toolbar, do:

(display

 (make-instance

  'interface

  :toolbar-items (list print-button)))
