Like an 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, the 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.
