        g.strokeLine(room.x, room.y + 20, room.x + room.width, room.y + 20);
        g.setFill(Color.BLACK);
        g.fillText(room.location.name(), room.x + 4, room.y + 15);
        g.setFill(Color.BLUE);

            int dy = 20;
            for (final String id : locationsContents.get(room.location)) {
                g.fillText(" (" + id + ")", room.x + 10, room.y + dy + 20);
                dy += 20;
            }
