Examples of mxGraph

com.mxgraph.view.mxGraph
Implements a graph object that allows to create diagrams from a graph model and stylesheet.
Images
To create an image from a graph, use the following code for a given XML document (doc) and File (file): Image img = mxCellRenderer.createBufferedImage( graph, null, 1, Color.WHITE, false, null); ImageIO.write(img, "png", file); If the XML is given as a string rather than a document, the document can be obtained using mxUtils.parse. This class fires the following events: mxEvent.ROOT fires if the root in the model has changed. This event has no properties. mxEvent.ALIGN_CELLS fires between begin- and endUpdate in alignCells. The cells and align properties contain the respective arguments that were passed to alignCells. mxEvent.FLIP_EDGE fires between begin- and endUpdate in flipEdge. The edge property contains the edge passed to flipEdge. mxEvent.ORDER_CELLS fires between begin- and endUpdate in orderCells. The cells and back properties contain the respective arguments that were passed to orderCells. mxEvent.CELLS_ORDERED fires between begin- and endUpdate in cellsOrdered. The cells and back arguments contain the respective arguments that were passed to cellsOrdered. mxEvent.GROUP_CELLS fires between begin- and endUpdate in groupCells. The group, cells and border arguments contain the respective arguments that were passed to groupCells. mxEvent.UNGROUP_CELLS fires between begin- and endUpdate in ungroupCells. The cells property contains the array of cells that was passed to ungroupCells. mxEvent.REMOVE_CELLS_FROM_PARENT fires between begin- and endUpdate in removeCellsFromParent. The cells property contains the array of cells that was passed to removeCellsFromParent. mxEvent.ADD_CELLS fires between begin- and endUpdate in addCells. The cells, parent, index, source and target properties contain the respective arguments that were passed to addCells. mxEvent.CELLS_ADDED fires between begin- and endUpdate in cellsAdded. The cells, parent, index, source, target and absolute properties contain the respective arguments that were passed to cellsAdded. mxEvent.REMOVE_CELLS fires between begin- and endUpdate in removeCells. The cells and includeEdges arguments contain the respective arguments that were passed to removeCells. mxEvent.CELLS_REMOVED fires between begin- and endUpdate in cellsRemoved. The cells argument contains the array of cells that was removed. mxEvent.SPLIT_EDGE fires between begin- and endUpdate in splitEdge. The edge property contains the edge to be splitted, the cells, newEdge, dx and dy properties contain the respective arguments that were passed to splitEdge. mxEvent.TOGGLE_CELLS fires between begin- and endUpdate in toggleCells. The show, cells and includeEdges properties contain the respective arguments that were passed to toggleCells. mxEvent.FOLD_CELLS fires between begin- and endUpdate in foldCells. The collapse, cells and recurse properties contain the respective arguments that were passed to foldCells. mxEvent.CELLS_FOLDED fires between begin- and endUpdate in cellsFolded. The collapse, cells and recurse properties contain the respective arguments that were passed to cellsFolded. mxEvent.UPDATE_CELL_SIZE fires between begin- and endUpdate in updateCellSize. The cell and ignoreChildren properties contain the respective arguments that were passed to updateCellSize. mxEvent.RESIZE_CELLS fires between begin- and endUpdate in resizeCells. The cells and bounds properties contain the respective arguments that were passed to resizeCells. mxEvent.CELLS_RESIZED fires between begin- and endUpdate in cellsResized. The cells and bounds properties contain the respective arguments that were passed to cellsResized. mxEvent.MOVE_CELLS fires between begin- and endUpdate in moveCells. The cells, dx, dy, clone, target and location properties contain the respective arguments that were passed to moveCells. mxEvent.CELLS_MOVED fires between begin- and endUpdate in cellsMoved. The cells, dx, dy and disconnect properties contain the respective arguments that were passed to cellsMoved. mxEvent.CONNECT_CELL fires between begin- and endUpdate in connectCell. The edge, terminal and source properties contain the respective arguments that were passed to connectCell. mxEvent.CELL_CONNECTED fires between begin- and endUpdate in cellConnected. The edge, terminal and source properties contain the respective arguments that were passed to cellConnected. mxEvent.REPAINT fires if a repaint was requested by calling repaint. The region property contains the optional mxRectangle that was passed to repaint to define the dirty region.
