Class mxLayoutManager

  • public class mxLayoutManager
extends mxEventSource
    Implements a layout manager that updates the layout for a given transaction. The following example installs an automatic tree layout in a graph: new mxLayoutManager(graph) { mxCompactTreeLayout layout = new mxCompactTreeLayout(graph); public mxIGraphLayout getLayout(Object parent) { if (graph.getModel().getChildCount(parent) > 0) { return layout; } return null; } }; This class fires the following event: mxEvent.LAYOUT_CELLS fires between begin- and endUpdate after all cells have been layouted in layoutCells. The cells property contains all cells that have been passed to layoutCells.
