Description

The class password-pane is a pane designed for entering passwords, such that when the password is entered it is not visible on the screen. password-pane inherits most of its functionality from text-input-pane. It starts with the initial text and caret position specified by the arguments text and caret-position respectively, and limits the number of characters entered with the max-characters argument (which defaults to nil, meaning there is no maximum).

The password pane can be enabled and disabled with the text-input-pane accessor text-input-pane-enabled.

overwrite-character is a base-char which is the character to display instead of the real characters. The default value of overwrite-character is #\*.

Examples

(setq password-pane (capi:contain
                     (make-instance
                      'capi:password-pane
                      :callback 
                      #'(lambda (password interface)
                                (capi:display-message
                                "Password: ~A"
                                password)))))
