    }
}

IntelliJ IDEA 提示

在 "getContentPane().add(weightTabbedPane, gridConstraints);" 上存在错误。

但我不知道如何修复它。IntelliJ IDEA 提供了创建私有方法的选项,但是否有其他方法来解决这个问题呢?任何建议都会有帮助。

IntelijIdea says

> Error on "getContentPane().add(weightTabbedPane, gridConstraints);"

but I don't know how to fix it. The IntelijIdea gives the option to create a private method but is there any other way to fix this. Any advice would be helpful.

当您扩展JFrame或JPanel时,不需要获取getContentPane()!您已经在一个容器中。只需调用add将组件添加到容器中。

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.Rectangle2D;

public class WeightMonitor extends JFrame {

    // 菜单
    JMenuBar mainMenuBar = new JMenuBar();
    JMenu fileMenu = new JMenu("File");
    JMenuItem newMenuItem = new JMenuItem("New Weight File");
    JMenuItem openMenuItem = new JMenuItem("Open Weight  File");
    JMenuItem saveMenuItem = new JMenuItem("Save Weight  File");
    JMenuItem exitMenuItem = new JMenuItem("Exit");

    // 其他部分...

    public WeightMonitor() {
        // 构造函数
        setTitle("Weight Monitor");
        setResizable(true);

        setJMenuBar(mainMenuBar);
        mainMenuBar.add(fileMenu);
        fileMenu.add(newMenuItem);
        fileMenu.add(openMenuItem);
        fileMenu.add(saveMenuItem);
        fileMenu.addSeparator();
        fileMenu.add(exitMenuItem);

        // 其他部分...
        
        getContentPane().setLayout(new GridBagLayout());
        GridBagConstraints gridConstraints;

        pack();
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        setBounds((int) (0.5 * (screenSize.width - getWidth())),
                (int) (0.5 * (screenSize.height - getHeight())),
                getWidth(), getHeight());
    }

    // 其他部分...
}

class WeightPlotPanel extends JPanel {
    // 其他部分...

    public void paintComponent(Graphics g) {
        Rectangle2D.Double plotFrame;
        Graphics2D g2D = (Graphics2D) g;
        super.paintComponent(g2D);

        // 绘制绘图框架
        plotFrame = new Rectangle2D.Double(50, 40, 420, 280);
        g2D.setPaint(Color.WHITE);
        g2D.fill(plotFrame);
        g2D.setStroke(new BasicStroke(2));
        g2D.setPaint(Color.BLACK);
        g2D.draw(plotFrame);

        g2D.dispose();

        weightTabbedPane.setPreferredSize(new Dimension(500,  400));
        weightTabbedPane.addTab("Weight Editor", editorPanel);
        weightTabbedPane.addTab("Weight Plot", plotPanel);
        GridBagConstraints gridConstraints = new GridBagConstraints();
        gridConstraints.gridx = 0;
        gridConstraints.gridy = 0;
        add(weightTabbedPane, gridConstraints);

        editorPanel.setBackground(new Color(192, 192, 255));
        editorPanel.setLayout(new GridBagLayout());
        plotPanel.setBackground(new Color(255, 192, 192));
    }
}
英文:

No need to get getContentPane() When you extend JFrame or JPanel! You are already in a container. Just call add to add a component to the container.

import java.awt.*;
import java.awt.event.*;

JMenuItem openMenuItem = new JMenuItem("Open Weight  File");
JMenuItem saveMenuItem = new JMenuItem("Save Weight  File");
JMenuItem exitMenuItem = new JMenuItem("Exit");
//
public static void main(String args[]){
//create frame
new WeightMonitor().setVisible(true);
}
public WeightMonitor(){
//frame constructor
setTitle("Weight Monitor");
setResizable(true);
setJMenuBar(mainMenuBar);
mainMenuBar.add(fileMenu);
fileMenu.add(newMenuItem);
fileMenu.add(openMenuItem);
fileMenu.add(saveMenuItem);
fileMenu.addSeparator();
fileMenu.add(exitMenuItem);
newMenuItem.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)  {
newMenuItemActionPerformed(e);  }
});
openMenuItem.addActionListener(new ActionListener()  {
public void actionPerformed(ActionEvent e)  {
openMenuItemActionPerformed(e);  }  });
saveMenuItem.addActionListener(new ActionListener()  {
public void actionPerformed(ActionEvent e)  {
saveMenuItemActionPerformed(e);  }  });
exitMenuItem.addActionListener(new ActionListener()  {
public void actionPerformed(ActionEvent e)  {
exitMenuItemActionPerformed(e);  }  });
addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent evt) {
exitForm(evt);
}
});
getContentPane().setLayout(new GridBagLayout());
GridBagConstraints gridConstraints;
pack();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds((int) (0.5 * (screenSize.width - getWidth())),
(int) (0.5 * (screenSize.height - getHeight())),
getWidth(), getHeight());
}
private void newMenuItemActionPerformed(ActionEvent e)  {  }
private void openMenuItemActionPerformed(ActionEvent e)  {  }
private void saveMenuItemActionPerformed(ActionEvent e)  {  }
private void exitMenuItemActionPerformed(ActionEvent e)  {  }
private void exitForm(WindowEvent evt){
System.exit(0);
}
}
class WeightPlotPanel extends JPanel
{
//Declaration of tab control and panels
JTabbedPane weightTabbedPane = new JTabbedPane();
JPanel editorPanel = new JPanel();
WeightPlotPanel plotPanel = new WeightPlotPanel();
public void paintComponent(Graphics g)
{
Rectangle2D.Double plotFrame;
Graphics2D g2D = (Graphics2D) g;
super.paintComponent(g2D);
//draw plot frame
plotFrame = new Rectangle2D.Double(50, 40, 420, 280);
g2D.setPaint(Color.WHITE);
g2D.fill(plotFrame);
g2D.setStroke(new BasicStroke(2));
g2D.setPaint(Color.BLACK);
g2D.draw(plotFrame);
g2D.dispose();
//pack();
weightTabbedPane.setPreferredSize(new Dimension(500,  400));
weightTabbedPane.addTab("Weight Editor", editorPanel);
weightTabbedPane.addTab("Weight Plot", plotPanel);
GridBagConstraints gridConstraints = new GridBagConstraints();
gridConstraints.gridx = 0;
gridConstraints.gridy = 0;
add(weightTabbedPane, gridConstraints);
editorPanel.setBackground(new Color(192, 192, 255));
editorPanel.setLayout(new GridBagLayout());
plotPanel.setBackground(new Color(255, 192, 192));
}
}

JPanel继承自类java.awt.Container,因此JPanel类本身就是一个容器。

方法getContentPane()没有实现。

将以下行进行替换:

getContentPane().add(weightTabbedPane, gridConstraints);

改为

add(weightTabbedPane, gridConstraints);
英文:

JPanel inherit the class java.awt.Container, so the class JPanel is a container itself.

There is no implementation of the method getContentPane().

Replace the line

getContentPane().add(weightTabbedPane, gridConstraints);

by

add(weightTabbedPane, gridConstraints);
