界面设计布局的问题.add(xxx, BorderLayout.SOUTH)还是跑到下面了

[wgf42421]

extends JFrame的效果是这样的



extends JPanel的效果是这样的….没有填充到整个窗口

    public static void main(String[] args) {
        JFrame frame = new JFrame();
        ResultTable pan = new ResultTable("1");
        frame.add(pan);
        frame.setSize(760, 670);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    
    }

Q1.我想让它填充到整个窗口要怎么做呢?

pSouth = new JPanel();
pSouth.add(btnAdd);
pSouth.add(btnDelete);
add(pSouth, BorderLayout.SOUTH);
add(new JScrollPane(table), BorderLayout.CENTER);
Q2.按钮为什么会跑到左边去,怎么解决?

1 把frame.setSize(760,670);改成 frame.pack();

To 楼上
不好意思发错了..extends JFrame是这个
http://s283.photobucket.com/albums/kk320/wgf4242/Upload/?action=view¤t=2010-01-09193241.png&newest=1

不管怎么拉窗口,面板表格都是自动扩展到两侧的..不像顶楼的图那样被圈一在一个小范围了.
pack不行啊..一拉窗口表格大小也不跟着变.

[wgf42421]

再举个例子.

JTextField tField = new JTextField(10);
我直接插入tField,填充整个窗口.

setLayout(new GridLayout(3,1));
此时插入tField,则占1/3屏幕.

但是我如果插入panel t,再向t中插入tField,则占一小块地方,10个字符位置.
我想在t中插入tField也让它像原来那样填充整个t面板怎么做?

public class T extends JFrame {

    JTextField tField,t2,t3;

    public T() {
        tField = new JTextField(10);
        t2 = new JTextField(10);
        setSize(760, 670);
        setLayout(new GridLayout(3,1));
        
        JPanel t = new JPanel();
        t.setLayout(new FlowLayout());
        t.add(tField);
        add(t);
        add(t2);
        setVisible(true);
    }
    public static void main(String[] args) {
        new T();
    }
}

填上代码..

[huntor]

你的问题太奇怪了。你有没有在ResultTable中table的大小？
改变窗口宽度是table跟着变化。

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
DefaultTableModel model = new DefaultTableModel(5 ,5);
frame.getContentPane().add(new JScrollPane(new JTable(model)),BorderLayout.CENTER);
JPanel buttonPanel = new JPanel();
buttonPanel.add(new JButton("Ok"));
buttonPanel.add(new JButton("Cancel"));
frame.getContentPane().add(buttonPanel,BorderLayout.SOUTH);
frame.pack();
frame.setVisible(true);

[huntor]

import javax.swing.*;
import javax.swing.table.*;
import java.util.*;
import java.awt.*;

public class T extends JFrame {
	JTextField tField,t2,t3; 
	
	public T() {
		super("T");
		tField = new JTextField(10);
		t2 = new JTextField(10);
		setSize(760, 670);
		setLayout(new GridLayout(3,1));
		JPanel t = new JPanel();
		t.setLayout(new GridLayout(1,1)); 
		t.add(tField);
		add(t);
		add(t2);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		setVisible(true);
	} 
	public static void main(String[] args) {
		SwingUtilities.invokeLater(new Runnable(){
				public void run(){
					new T();
				}
			});
	}
}

[wgf42421]

我没有在ResultTable有setSize.
即使用了也没有反应..table的宽度不变化...感觉是被圈起来了一样..

[wgf42421]

3Q.huntor

t设置成GirdLayout(1,1)..这是关键哪..

[huntor]

布局管理器现在基本复杂一点的使用MiGLayout，简单的使用DesignGridLayout

[wgf42421]

再进一步问:
让panel t填充满JtextField后,
t.add(new JButton("new"), BorderLayout.SOUTH); //现在的效果是和JtextField各占面板一半大小
我想在t面板的底部仅占一个按钮的高度占一行,要怎么做呢?

如图..

帖个全图....大家给点主意...

To yel_hb,
那个关于我们的JDialog给个调用的类吧..JDialog不太懂.弄了半天没运行起来它..
[/Quote]
这是一个单例模式，在main方法中写这么一句就行了：

AboutDialog.getInstance(null).setVisible(true);

centerPanel.add(label);

}

private void createUP() {
JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT, 12, 10));
panel.add(new JLabel("关于我们"));
this.add(panel, BorderLayout.NORTH);
}
}
这是一个“关于我们”的面板，跟你描述的问题差不多，可能对你有用

不错，学习了，AWT看来要多学下！

To yel_hb,
那个关于我们的JDialog给个调用的类吧..JDialog不太懂.弄了半天没运行起来它..

[py330316117]

你一个帖子要问几个问题？
才20分，自己研究去吧。
楼上这个运行什么也不会得。JOptionPane.showMessageDialog(null, "对不起，中国的身份证为15位或18位", "提示",
JOptionPane.ERROR_MESSAGE); 这个提示信息的写法，当然还有错误信息等一些写法，由于你只有20分，建议你再发个帖子吧。。。。再有问题不予解决
