用JPanel将ChartPanel添加到JTabbedPane

本文介绍了使用JPanel将ChartPanel添加到JTabbedPane的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想将 JFreeChart 添加到 JPanel ,然后添加 JPanel JTabbedPane 。我设法在 JFrame 上显示 JFreeChart ,但我想添加 JFreeChart 作为 JTabbedPane 的第四个标签。

I want to add JFreeChart to JPanel and then add JPanel to JTabbedPane. I managed to display JFreeChart on JFrame, but I want to add JFreeChart as a 4th tab of JTabbedPane.

要显示的代码图表:

public class Chart extends javax.swing.JPanel {

  private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

        JPanel jPanel1 = new JPanel();
        DefaultCategoryDataset dataset = new DefaultCategoryDataset();
        dataset.setValue(60, "Marks", "Student 1");
        dataset.setValue(40, "Marks", "Student 2");
        dataset.setValue(90, "Marks", "Student 3");
        dataset.setValue(50, "Marks", "Student 4");
        dataset.setValue(70, "Marks", "Student 5");
        dataset.setValue(30, "Marks", "Student 6");

        JFreeChart chart = ChartFactory.createBarChart(
            "Student Marks", "Student Name", "Marks", dataset,
            PlotOrientation.VERTICAL, false, true, false);
        CategoryPlot p = chart.getCategoryPlot();
        p.setRangeGridlinePaint(Color.BLACK);
        ChartPanel panel = new ChartPanel(chart);
        panel.setDomainZoomable(true);
        jPanel1.add(panel, BorderLayout.CENTER);
        panel.setPreferredSize(new java.awt.Dimension(500, 270));

  }

要添加到TabbedPane的代码:

Code to add to TabbedPane:

tabStoreTrans.add("chart", new Chart());


推荐答案

如,您可以将元件添加到标签页窗格。 ChartPanel JPanel 的子类,是这样的组件。除了之外,您还可以使用

As shown in How to Use Tabbed Panes, you can add components to a tabbed pane. ChartPanel, a subclass of JPanel, is such a component. In addition to these examples, you can use the example below to experiment with other features.

由于您是新用户,使用NetBeans GUI编辑器,隐含在您的问题中,但继续使用NetBeans IDE。

As you are new, limit using the NetBeans GUI editor, implied in your question, but continue to use the NetBeans IDE.
