问题描述
我正在尝试制作一个专门嵌入 JInternalFrame
面板中的图表;它是来自库 JFreeChart
的饼图。我想将图表嵌入一个变量名为 jpPaneles
的面板上,但事实证明这是不可能的。这对我的项目来说非常重要,所以如果有人有时间帮助我,我会非常感激。我在NetBeans GUI编辑器中工作。这是代码,您可以看到我尝试将frame1添加到面板。
I am trying to make a chart that is embedded specifically in a panel on a JInternalFrame
; it is a pie chart from the library JFreeChart
. I want to embed the chart on a panel which goes by the variable name jpPaneles
, but it has proven to be impossible. This is really crucial for my project, so if anyone has the time to help me out, I would greatly appreciate it. I am working in NetBeans GUI editor. Here is the code and you can see I try to add frame1 to a panel.
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PiePlot3D;
import org.jfree.data.general.DefaultPieDataset;
public class Eventad extends javax.swing.JInternalFrame {
public Eventad() {
initComponents();
}
public void updateChart() {
}
public static void main(String arg[]) {
DefaultPieDataset pieDataset = new DefaultPieDataset();
pieDataset.setValue("One", new Integer(10));
pieDataset.setValue("Two", new Integer(20));
pieDataset.setValue("Three", new Integer(30));
pieDataset.setValue("Four", new Integer(10));
pieDataset.setValue("Five", new Integer(20));
pieDataset.setValue("Six", new Integer(10));
JFreeChart chart = ChartFactory.createPieChart3D(
"3D Pie Chart", pieDataset, true, true, true);
PiePlot3D p = (PiePlot3D) chart.getPlot();
p.setForegroundAlpha(0.5f);
ChartFrame frame1 = new ChartFrame("3D Pie Chart", chart);
frame1.setVisible(true);
frame1.setSize(200, 200);
//Here im trying to add the frame1 to the Jpanel
this.jpPaneles.add(frame1);
}
}
推荐答案
使用您的图表
创建并将 ChartPanel
添加到 JInternalFrame
。将 JInternalFrame
添加到 JDesktopPane
。请参阅 如何使用内部框架 更多。
Use your chart
to create a ChartPanel
and add the ChartPanel
to the JInternalFrame
. Add the JInternalFrame
to a JDesktopPane
. See How to Use Internal Frames for more.

import java.awt.EventQueue;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.data.general.DefaultPieDataset;
/** @see http://stackoverflow.com/questions/8199766 */
public class InternalPie {
private void display() {
JFrame f = new JFrame("InternalPie");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
DefaultPieDataset pieDataset = new DefaultPieDataset();
pieDataset.setValue("One", new Integer(10));
pieDataset.setValue("Two", new Integer(20));
pieDataset.setValue("Three", new Integer(30));
pieDataset.setValue("Four", new Integer(10));
pieDataset.setValue("Five", new Integer(20));
pieDataset.setValue("Six", new Integer(10));
JFreeChart chart = ChartFactory.createPieChart3D(
"3D Pie Chart", pieDataset, true, true, true);
ChartPanel cp = new ChartPanel(chart);
JInternalFrame jif = new JInternalFrame(
"Chart", true, true, true, true);
jif.add(cp);
jif.pack();
jif.setVisible(true);
JDesktopPane dtp = new JDesktopPane();
dtp.add(jif);
f.add(dtp);
f.pack();
f.setSize(700, 500);
f.setLocationRelativeTo(null);
f.setVisible(true);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
new InternalPie().display();
}
});
}
}
