如标题中所述.我使用BorderLayout()在另一个上面有两个JPanel.
import java.awt.*;
import javax.swing.*;
public class myForm(){
public static void main(String[] args) {
JFrame myFrame = new JFrame("SingSong");
myFrame.setLocation(100,100);
myFrame.setSize(new Dimension(1024,800));
myFrame.setLayout(new BorderLayout());
JPanel jp = new JPanel();
jp.setBackground(new Color(0x00FF00FF));
JPanel jp2 = new JPanel(new BorderLayout());
jp2.setBackground(new Color(0x00000000));
jp.setPreferredSize(new Dimension(100,400));
jp2.setPreferredSize(new Dimension(100,400));
jp2.setLocation(0,512);
myFrame.add(jp2,BorderLayout.SOUTH);
myFrame.add(jp,BorderLayout.NORTH);
}
}
它们各占一半,但我怎么能设置它以便它们总是占用JFrame的一半,即使调整大小？
(P.S.我通常使用更好的变量名称,我只是把它作为SSCCE)
解决方法
试试GridLayout
JFrame myFrame = new JFrame("SingSong");
myFrame.setLocation(100,100);
myFrame.setSize(new Dimension(1024,800));
GridLayout layout = new GridLayout(2,1);
myFrame.setLayout(layout);
JPanel jp = new JPanel();
jp.setBackground(new Color(0x00FF00FF));
JPanel jp2 = new JPanel(new BorderLayout());
jp2.setBackground(new Color(0x00000000));
myFrame.add(jp);
myFrame.add(jp2);
myFrame.setVisible(true);
