Java GridBagLayout 简单使用

    这里只介绍了很基础布局构建及使用，主要是关于 GridBagLayout.

    首先整套流程大概是，

    声明一个 GridBagLayout 对象

    private GridBagLayout gridBagLayoutFrame = new GridBagLayout();

    然后把当前类的容器布局管理器设置为 GridBagLayout

    this.setLayout(gridBagLayoutFrame);

    最后声明一个 JPanel 用于添加组件。（当然也可以是别的Panel。如JTabbedPane等）

    private JPanel checkBoxTreePanel = new JPanel();

    private JTabbedPane tabbedPane = new JTabbedPane();

    然后就可以开始使用这个布局管理器来增加和设置组件了。

add(Component comp, Object constraints)

    下面是一个例子：

   

import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JTabbedPane;
import javax.swing.JPanel;


public class WriteForBlog extends JFrame
{
    private GridBagLayout gridBagLayoutFrame = new GridBagLayout();
    private JTabbedPane tabbedPane = new JTabbedPane();
    private JPanel panelOne = new JPanel();
    private JPanel panelTwo = new JPanel();
    
    public WriteForBlog()
    {
        jbInit();
    }
    
    private void jbInit()
    {
        this.setLayout(gridBagLayoutFrame);
        this.setBounds(200, 200, 1000, 600);
        tabbedPane.add(panelOne, "One");
        tabbedPane.add(panelTwo, "Two");
        
        this.add(tabbedPane, new GridBagConstraints(0, 0, 1, 1, 1.0, 1.0
                 ,GridBagConstraints.NORTHWEST, GridBagConstraints.BOTH, new Insets(0, 0, 0, 0), 0, 0));
    }
    
    public static void main(String[] args)
    {
        WriteForBlog test = new WriteForBlog();
        test.setVisible(true);
    }

}
