如标题中所述。我有两个使用 BorderLayout()
的 JPanel,一个在另一个上面。
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,但我如何设置它以使它们始终占据 JFrame 的一半,即使调整大小也是如此?
(P.S. 我通常使用更好的变量名,我只是把它作为一个 SSCCE)
最佳答案
尝试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);
