You can add dynamic control of window titles using the functions illustrated in the section.
Firstly we add a counter to the title of new
demo
windows:
(defvar *demo-title-counter* 0)
(defmethod capi:interface-extend-title ((self demo) title)
(format nil "~A - ~D"
(call-next-method)
(incf *demo-title-counter*)))
(capi:display (make-instance 'demo))
Then we specify common prefix for all interface window titles:
(capi:set-default-interface-prefix-suffix
:prefix "My " :suffix nil )
(capi:display (make-instance 'demo))
