Returns class of a window or the class to instantiate when running a
form (that is, it is the accessor/setter of the
class slot of a form). A form (a special window
used to design actual application windows) is always an instance of
class, to provide its special widget-editing behavior. The class
property indicates the intended class that should be instantiated for
the application when the form is run or the window associated with the
form is created. This function accesses the class slot (since
class is a Common Lisp symbol, its name is not
available to be the accessor/setter).
But note that it is uncommon to need to use that function
programmatically (one typically sets the class slot upon creation of a
window with make-window or using the
class slot in an inspector window). The form (using
Common Lisp functions)
object)) also serves as an accessor.
This function can also be applied to a window object which is not a
form, in which case it returns what
object)) would return, the class of the window.
