Example 2 with YPoint

use of y.geom.YPoint in project binnavi by google.

the class YHelpers method openFolder.

        // move grouped nodes to former location of folder node
        LayoutTool.moveSubgraph(graph, innerNodes.nodes(), folderP.x - gBox.x, folderP.y - gBox.y);
    }
    graph.firePostEvent();

    }
    // to the node
