如何将JPanel分成左右两部分？

Question

我想将JPanel分成左右两部分。我怎么做 ？之后，我会将面板放在左右两侧。

Answer 1

如果没有必要调整它们的大小，你可以只需使用BorderLayout并将您的面板插入BorderLayout.EAST和BorderLayout.WEST：

JPanel panel = new JPanel(new BorderLayout()); 
panel.add(leftPanel, BorderLayout.WEST); 
panel.add(rightPanel, BorderLayout.EAST); 

你也可以考虑使用JSplitPane它允许调整UI：

JSplitPane pane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, 
            leftPanel, rightPanel); 

Answer 2

如果您使用JSPlitPane这很容易。

Answer 3

有两种方式

• 使用网格布局

• 使用调整JSplitPane（隐藏分频器）

Answer 4

JPanel panel = new JPanel(new BorderLayout()); 
panel.add(c1, BorderLayout.WEST); 
panel.add(c2, BorderLayout.EAST); 

JPanel panel = new JPanel(new GridLayout(1, 2)); 
panel.add(c1); 
panel.add(c2); 

Answer 5

使用JSplitPane或网格布局

Answer 6

您可以使用SplitPane作为斯特凡诺Aivalis建议。
或
在JPanel上使用Border Layout Manager。
将您的左侧组件放在WEST侧，并将右侧组件放在布局管理器的EAST侧。

JPanel panel = new JPanel(new BorderLayout()); 
panel.add(c1, BorderLayout.WEST); 
panel.add(c2, BorderLayout.EAST); 

Answer 7

JPanel leftPanel = new JPanel(); 
JPanel rightPanel = new JPanel(); 
JSplitPane pane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, leftPanel, rightPanel); 

Answer 8

JPanel example = new JPanel(new GridLayout(1,2)); 
example.add(p1); 
example.add(p2); 

Answer 9

import java.awt.BorderLayout; 
import javax.swing.JFrame; 
import javax.swing.JPanel; 
import javax.swing.JSplitPane; 

public class Display{ 

JFrame frame=new JFrame("Drawing"); 
North north; 
South south; 
East east; 
West west; 
Center center; 
public int width=600,height=600; 

public Display() { 
    // TODO Auto-generated constructor stub 
    frame.setSize(width,width); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    frame.setLocationRelativeTo(null); 
    frame.setResizable(true); 

    north=new North(frame); 
    south=new South(frame); 
    east=new East(frame); 
    west=new West(frame); 
    center=new Center(frame); 

    frame.setLayout(new BorderLayout()); 


JSplitPane pane2=new JSplitPane(JSplitPane.VERTICAL_SPLIT,west,east); 

frame.add(pane2); 

    frame.setVisible(true); 

    } 

}
