先f.seResizable(false);
之后根据用户触发的事件判断变化seResizable(false);or seResizable(true);
就OK了!

[007remember]

调用JFrame 中的setResizable（）
例如：
JFrame f = new JFrame("Fixed size");
f.seResizable(false);
此时窗体最大化按钮不显示或无效
通过程序代码仍然可以改变大小，此限制只是用于用户。

give me a reason?

[terrorist]

? f.seResizable(false);之后就不能改变大小了

[007remember]

事实就是如此
no reason

please write a programme to prove it

这个问题号解决，先f.seResizable(true);改变后在f.seResizable(false);不就得了

[terrorist]

问题是，要求用户能拖动大小的

[CoolAbu]

你seResizable(false);然后做2个Button，一个是增大，一个缩小。

你又不想让它最大化，又想能够Resize，这本身有点矛盾呀。

[terrorist]

我只是想用户点击最大化后没有动作，但是可以手动拖大拖小Frame， ：） 请教了

[007remember]

目前我还实现不了手动拖大拖小Frame
我写了个通过程序代码改变窗体大小的程序
注意45行代码调用：f.setResizable(false);

代码如下：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class SimpleFrameTest implements ComponentListener
{
public void componentMoved(ComponentEvent e) {
Component c = e.getComponent();
Point p = c.getLocation();
System.out.println("Component moved to (" + p.x + ", "
+ p.y + ")");
}

public void componentResized(ComponentEvent e) {
Component c = e.getComponent();
Dimension d = c.getSize();
System.out.println("Component resized: width " + d.width +
", height " + d.height);
}

public void componentShown(ComponentEvent e) {
System.out.println("Component made visible");
}

public void componentHidden(ComponentEvent e) {
System.out.println("Component made invisible");
}

public static void main(String[] args)
{
JFrame f = new JFrame("Simple frame test");
f.setSize(300, 200);
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent evt) {
System.exit(0);
}
});

f.setVisible(true);
f.setResizable(false);

try {
Thread.sleep(5000); // Delay a bit
f.getContentPane().setLayout(null);
Thread.sleep(5000); // Delay a bit
f.setSize(100, 100); // Change size
Thread.sleep(5000); // Delay a bit
f.setSize(200, 200); // Move ourselves
Thread.sleep(5000); // Delay a bit
Thread.sleep(5000); // Delay a bit
f.setSize(300, 400); // Move ourselves
Thread.sleep(5000); // Delay a bit
f.setSize(600, 600); // Change size
Thread.sleep(5000); // Delay a bit
f.setSize(800, 800);

} catch (Exception e) {
System.out.println(e);
}

System.exit(0);
}
}
代码如下：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class SimpleFrameTest implements ComponentListener
{
public void componentMoved(ComponentEvent e) {
Component c = e.getComponent();
Point p = c.getLocation();
System.out.println("Component moved to (" + p.x + ", "
+ p.y + ")");
}

public void componentResized(ComponentEvent e) {
Component c = e.getComponent();
Dimension d = c.getSize();
System.out.println("Component resized: width " + d.width +
", height " + d.height);
}

public void componentShown(ComponentEvent e) {
System.out.println("Component made visible");
}

public void componentHidden(ComponentEvent e) {
System.out.println("Component made invisible");
}

public static void main(String[] args)
{
JFrame f = new JFrame("Simple frame test");
f.setSize(300, 200);
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent evt) {
System.exit(0);
}
});

f.setVisible(true);
f.setResizable(false);

try {
Thread.sleep(5000); // Delay a bit
f.getContentPane().setLayout(null);
Thread.sleep(5000); // Delay a bit
f.setSize(100, 100); // Change size
Thread.sleep(5000); // Delay a bit
f.setSize(200, 200); // Move ourselves
Thread.sleep(5000); // Delay a bit
Thread.sleep(5000); // Delay a bit
f.setSize(300, 400); // Move ourselves
Thread.sleep(5000); // Delay a bit
f.setSize(600, 600); // Change size
Thread.sleep(5000); // Delay a bit
f.setSize(800, 800);

} catch (Exception e) {
System.out.println(e);

System.exit(0);
