[英]Customizing JGraphX
我一直在使用JGraphX來顯示一些數據(簡單的離散圖),我想知道如何用JGraphX庫做以下事情:
謝謝,ExtremeCoder
這是一個例子:
mxGraph graph = new mxGraph()
{
// Make all edges unmovable
public boolean isCellMovable(Object cell)
{
return !getModel().isEdge(cell);
}
// Make all vertex boxes unresizable
public boolean isCellResizable(Object cell)
{
return !getModel().isVertex(cell);
}
};
// Make all vertices and edges uneditable
graph.setCellsEditable(false);
// Make all edges unbendable
graph.setCellsBendable(false);
// Get the selected vertex or edge
System.out.println(graph.getSelectionCell());
// To insert a vertex with a given color:
Object v1 = graph.insertVertex(parent, null, "Hello",
20, 20, 80, 30, "fillColor=#FF0000;");
// To modify the color of a vertex:
graph.setCellStyles(mxConstants.STYLE_FILLCOLOR, "#00FF00", new Object[]{v1});
