Question

我尝试在JGraphX中移动图形。我的第一次尝试是使用setGeometry，但这也会移动整个坐标系及其原点。所以这对我来说不是一个选择，因为移动几个图表时有点棘手。

我的第二次尝试

Object[] ver = graph.getChildVertices(graph.getDefaultParent());
graph.moveCells(ver, 100, 100, false);

移动所有细胞。到目前为止一切顺利，但边缘起点和终点改变了它的位置。

移动细胞后：

在移动单元格之前，边缘的位置正确。

那么如何将边缘的位置设置回正常的起点和终点？或者，我感谢将细胞移动到给定位置的任何其他方法。

编辑：如果我之前添加了一个布局，似乎只会发生此行为。如果没有布局，移动单元格将按预期工作。

mxGraph graph = new mxGraph();
    Object parent = graph.getDefaultParent();

    graph.getModel().beginUpdate();
    try
    {
        Object v1 = graph.insertVertex(parent, null, "Hello", 20, 20, 80,
                30);
        Object v2 = graph.insertVertex(parent, null, "World!", 240, 150,
                80, 30);
        graph.insertEdge(parent, null, "Edge", v1, v2);


    }
    finally
    {
        graph.getModel().endUpdate();
    }
    new mxHierarchicalLayout(graph).execute(graph.getDefaultParent());
    graph.getModel().beginUpdate();
    try
    {
        Object[] ver = graph.getChildVertices(graph.getDefaultParent());
        graph.moveCells(ver, 100, 100, false);
    }
    finally
    {
        graph.getModel().endUpdate();
    }
    mxGraphComponent graphComponent = new mxGraphComponent(graph);
    getContentPane().add(graphComponent);

Answer 1

我通读了这个JGraphx的api文档，并从xGraph类找到了有趣的属性：

<强> mxGraph.prototype.resetEdgesOnMove：

指定在移动连接的单元格后是否应重置边缘控制点。默认为false。

我会尝试切换它，看看它是否可能在这种情况下有所帮助。至少这会影响移动条件下的边缘行为。

Answer 2

使用 graph.getChildCells（）移动顶点和边：

    Object[] ver = graph.getChildCells(graph.getDefaultParent());
    graph.moveCells(ver, 100, 100, false);

import java.awt.BorderLayout; import java.awt.Container; import java.awt.Dimension; import java.awt.GridLayout; import javax.swing.ButtonGroup; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JRadioButton; import javax.swing.JTextField; public class GUI { public GUI() { JFrame frame = new JFrame(); // making the JFrame frame.setTitle("Donate Today!"); // sets JFrame title // Make the content pane with a set layout Container contentPane = frame.getContentPane(); contentPane.setLayout(new BorderLayout(5,5)); // makes a layout for aesthetics/organization // make right-hand panel where the donation form will appear JPanel right = new JPanel(new GridLayout(3,2,5,5)); right.setPreferredSize(new Dimension(400,160)); JLabel lblamount = new JLabel("Donation"); JLabel lblgender = new JLabel("Gender"); JTextField amount = new JTextField(); JRadioButton radioButton = new JRadioButton("Female"); JRadioButton radioButton_1 = new JRadioButton("Male"); JRadioButton radioButton_2 = new JRadioButton("Other"); ButtonGroup b1 = new ButtonGroup(); b1.add(radioButton); b1.add(radioButton_1); b1.add(radioButton_2); right.add(lblamount); right.add(amount); right.add(lblgender); JPanel rButtons = new JPanel(); rButtons.add(radioButton); rButtons.add(radioButton_1); rButtons.add(radioButton_2); right.add(rButtons); // makes the clear button JButton btnClear = new JButton("Clear"); btnClear.setPreferredSize(new Dimension(10,10)); // makes the submit button JButton btnSubmit = new JButton("Submit"); btnSubmit.setPreferredSize(new Dimension(10,10)); // adds both buttons to the form JPanel right.add(btnClear); right.add(btnSubmit); // make left-hand panel where the button menu selections will appear JPanel left = new JPanel(new GridLayout(3,1,5,5)); // specifies a grid layout for theh buttons left.setPreferredSize(new Dimension(195,225)); String arr[] = new String[] {"Budgeting", "About Us", "View Graph"}; for (int i=0; i<arr.length; i++) { // loops through the above array left.add(new JButton(arr[i])); //add button to lower pane } // adds everything to the JFrame contentPane.add(left, BorderLayout.WEST); //adding panel 1 to the top of the frame contentPane.add(right, BorderLayout.EAST); //adding panel 2 to the center of the frame frame.pack(); frame.setVisible(true); } public static void main(String[] args) { new GUI(); } } 只是移动所说的单元格，而是尝试做：

graph.moveCells(<params>);

这应该移动所述单元格及其子元素和边缘

JGraphX移动细胞并保持边缘
