如何將JPanel分成左右兩部分？

Question

我想將JPanel分成左右兩部分。我怎麼做 ？之後，我會將面板放在左右兩側。

Answer 1

如果沒有必要調整它們的大小，你可以只需使用BorderLayout並將您的面板插入BorderLayout.EAST和BorderLayout.WEST：

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

你也可以考慮使用JSplitPane它允許調整UI：

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

Answer 2

如果您使用JSPlitPane這很容易。

Answer 3

有兩種方式

• 使用網格佈局

• 使用調整JSplitPane（隱藏分頻器）

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或網格佈局

Answer 6

您可以使用SplitPane作爲斯特凡諾Aivalis建議。
或
在JPanel上使用Border Layout Manager。
將您的左側組件放在WEST側，並將右側組件放在佈局管理器的EAST側。

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); 

    } 

}
