如何将JPanel划分为左右段？

Question

我想将JPanel划分为左右段。 我怎么做 ？ 之后，我会在左右两侧放置面板。

Answer 1

如果不需要调整它们的大小，您只需使用BorderLayout并在BorderLayout.EAST和BorderLayout.WEST插入面板：

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

您还可以考虑使用允许调整UI大小的JSplitPane ：

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

Answer 2

如果使用JSPlitPane ，则非常容易。

Answer 3

有两种方法

• 使用GridLayout

• 使用JSplitPane（隐藏分隔符）

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GridLayout

Answer 6

您可以使用SplitPane作为Costis Aivalis建议。
要么
在JPanel上使用Border Layout Manager 。
将左侧组件放在WEST侧，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);

  }

 }
