我使用JGraphT库创建了一个图表:
@Override
public void actionPerformed(ActionEvent e) {
String a="1";
String b="2";
g.addVertex(a);
g.addVertex(b);
g.addEdge(a,b);
}
public static class MyEdge extends DefaultWeightedEdge { //weight
@Override
public String toString() {
return String.valueOf(getWeight());
}
}
我想在按下按钮后动态添加新顶点
IPersonRepository
如何刷新视图?

试试这个:
public void actionPerformed(ActionEvent e) {
String a="1";
String b="2";
[your mxGraph variable].getModel().beginUpdate();
g.addVertex(a);
g.addVertex(b);
g.addEdge(a,b);
[your mxGraph variable].getModel().endUpdate();
[your mxGraph variable].refresh();
}

TobiasH它没有用,但是我尝试过这样的事情并且运作正常
if (e.getSource() == add) {
String a = vertex.getText().toString();
if (a != null && !a.equals("")) {
g.addVertex(a);
vertexSet.add(a);
if (checked) {
String b = vertex1.getText().toString();
vertexSet.add(b);
edges.add(new Edge(a, b)); // zbiór krawędzi
g.addVertex(b);
g.addEdge(a, b);
}
layout.execute(graphAdapter.getDefaultParent());
}
}
