The cursor set by this function will be shown every time that specific object type is drawn in the container. For example, if a rectangle is being drawn in the container, the cursor set for object type CONTAINER_OBJECT_TYPE_RECT will be displayed. The container makes a copy of the cursor. Therefore, the user can delete a specific cursor.
