 	\fn void BView::MouseMoved(BPoint where, uint32 code,
-		const BMessage* a_message)
+		const BMessage* dragMessage)
 	\brief Hook method called when the mouse is moved.
 
 	The default implementation does nothing.
+
+	\param where The new location of the mouse in the view's coordinate system.
+	\param code One of the following:
+	- \c B_ENTERED_VIEW The cursor has just entered the view.
+	- \c B_INSIDE_VIEW The cursor is inside the view.
+	- \c B_EXITED_VIEW The cursor has left the view's bounds. This only gets sent
+	     if the scope of the mouse events that the view can receive has been
+	     expanded by SetEventMask() or SetMouseEventMask().
+	- \c B_OUTSIDE_VIEW The cursor is outside the view. This only gets sent if the
+	     scope of the mouse events that the view can receive has been expanded by
+	     SetEventMask() or SetMouseEventMask().
+	\param dragMessage If a drag-and-drop operation is taking place this is a
+	       pointer to a BMessage that holds the drag information, otherwise the
+	       pointer is \c NULL.
