| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments:
This function returns the currently selected top-level window in this
Lisp if this Lisp is the currently selected application, and otherwise
returns nil
. Returns the window even if it is
in another thread of the same Lisp.
This function may be useful for determining whether this Lisp (either a development environment or standalone application) is the application that is currently selected by the user, by simply checking whether the return value is true.
Note that the expression
(selected-window (screen *system*))
differs in that it will return the most recently selected top-level even when this Lisp is not the currently selected application. (See selected-window.)
See also set-foreground-window.
foreground-window simply calls selected-window on the screen.
