我在java应用程序中工作,它有很多组件,但我有一个JRadioButton的问题,它不是垂直的方式,还有其他任何方法使它垂直使用JPanel
我可以使用哪种最佳布局使这段代码比
更容易package item;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

您可以使用Box
设置
Box verticalBox = Box.createVerticalBox();
verticalBox.add(jRadioButtonA);
verticalBox.add(jRadioButtonB);
verticalBox.add(jRadioButtonC);
请参阅此可运行示例
import java.awt.GridLayout;
import javax.swing.Box;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.SwingUtilities;
public class MyPanel extends JPanel {
public MyPanel(){
JRadioButton jrb1 = new JRadioButton("Button 1");
JRadioButton jrb2 = new JRadioButton("Button 2");
JRadioButton jrb3 = new JRadioButton("Button 3");
Box box1 = Box.createVerticalBox();
box1.add(jrb1);
box1.add(jrb2);
box1.add(jrb3);
JRadioButton jrb4 = new JRadioButton("Button 4");
JRadioButton jrb5 = new JRadioButton("Button 5");
JRadioButton jrb6 = new JRadioButton("Button 6");
Box box2 = Box.createVerticalBox();
box2.add(jrb4);
box2.add(jrb5);
box2.add(jrb6);
JRadioButton jrb7 = new JRadioButton("Button 7");
JRadioButton jrb8 = new JRadioButton("Button 8");
JRadioButton jrb9 = new JRadioButton("Button 9");
Box box3 = Box.createVerticalBox();
box3.add(jrb7);
box3.add(jrb8);
box3.add(jrb9);
setLayout(new GridLayout(1, 3));
add(box1);
add(box2);
add(box3);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame frame = new JFrame();
frame.add(new MyPanel());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationByPlatform(true);
frame.setSize(300, 300);
frame.setVisible(true);
}
});
}
}

非常简单,只需使用GridLayout:
JPanel panel = new JPanel(new GridLayout(3,1));
panel.add(RButton1);
panel.add(RButton2);
panel.add(RButton3);
