view -- a gtk:text-view widget

The gtk:text-view-gutter function gets widget that has previously been set. The (setf gtk:text-view-gutter) function places widget into the gutter specified by win.

The wtype argument must be one of the values :left, :right, :top, or :bottom of the gtk:text-window-type enumeration.
