This control was removed from the 5.0/5.0.1 releases of Allegro CL, but has been restored in release 6.0.
This control is like a editable-text control, except that
the value may be any lisp object rather than a string only. When the
control's value is set programmatically to a new arbitrary lisp
object, on-print
event handler function for the control takes the object as its
argument and should return a string to be displayed in the
control. When the end user types into the control, read-from-string is called internally on the new
string to produce a new arbitrary lisp object that is then stored as
the value of the
control. Errors are trapped during the reading so that no break will
occur; if an error is signaled during the reading then nil is stored
as the value of the control.
