绑定帧大小及其对象大小

如何在改变帧大小之后更改代码，帧上其他对象的大小是否也会以相同的比例改变？绑定帧大小及其对象大小

package application; 

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

public class Program extends JFrame { 

    private GroupLayout layout; 
    private GroupLayout.Group groupX; 
    private GroupLayout.Group groupY; 

    public Program() { 
     initialize(); 
    } 

    private void initialize() { 
     this.layout = new GroupLayout(this.getContentPane()); 
     this.groupX = this.layout.createParallelGroup(GroupLayout.Alignment.LEADING); 
     this.groupY = this.layout.createParallelGroup(GroupLayout.Alignment.LEADING); 
    } 

    public void addComponent(Component component, int x, int y) { 

     getContentPane().setLayout(layout); 

     groupX.addGroup(layout.createSequentialGroup() 
       .addGap(x, x, x) 
       .addComponent(component, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE)); 

     groupY.addGroup(layout.createSequentialGroup() 
       .addGap(y, y, y) 
       .addComponent(component, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE));  
     layout.setHorizontalGroup(groupX); 
     layout.setVerticalGroup(groupY); 
    } 


    public static void main(String[] args) { 
     Program jf = new Program(); 
     jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     jf.setBounds(new Rectangle(0, 0, 250, 100)); 
     JButton p = new JButton("Click!!"); 
     jf.addComponent(p, 86, 20); 
     jf.setVisible(true); 
    } 
}

如何更改下面的代码，改变帧大小后，帧上其他对象的大小也会以相同的比例改变？

如果我理解正确，你想放大用户界面？如果是这样，那就不支持（并且与LayoutManager的任务无关）。你必须自己实施它，f.i.使用JLayer（jdk7）或JXLayer（jdk6） – kleopatra 2013-04-04 08:52:56

不。我不想放大UI。我想实现类似于C＃中的锚点，这意味着如果我改变框架的宽度，它的对象的宽度也会改变。 – user2049371 2013-04-04 09:36:50

好的，谢谢澄清（但请注意，您的图像是误导性的，因为字体大小随着按钮尺寸的增大而增加，除非您放大缩小时才会发生） – kleopatra 2013-04-04 09:42:15

我只想说，我不喜欢GroupLayout，不过这只是我：d

enter image description here

jButton1 = new javax.swing.JButton(); 

jButton1.setText("jButton1"); 

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(this); 
this.setLayout(layout); 
layout.setHorizontalGroup(
    layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) 
    .addGroup(layout.createSequentialGroup() 
    .addGap(152, 152, 152) 
    .addComponent(jButton1, javax.swing.GroupLayout.DEFAULT_SIZE, 143, Short.MAX_VALUE) 
    .addGap(175, 175, 175)) 
); 
layout.setVerticalGroup(
    layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) 
    .addGroup(layout.createSequentialGroup() 
    .addGap(137, 137, 137) 
    .addComponent(jButton1, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) 
    .addGap(94, 94, 94)) 
);

我知道这种方法可行。但我想使用参数，如x和y ... – user2049371 2013-04-04 09:33:49

只需修改代码，以取代x/y和宽度/高度值 – MadProgrammer 2013-04-04 09:42:34

_我不喜欢GroupLayout_我 - 但是，然后，它的设计用于建设者，而不是手工编码，所以它在传达后者方面做得很好:-) – kleopatra 2013-04-04 16:10:43

Try using GridBagLayout which is easier. 

private void initialize() { 
    getContentPane().setLayout(new GridBagLayout()); 
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    setBounds(new Rectangle(0, 0, 250, 100)); 
    JButton p = new JButton("Click!!"); 
    add(p, new GridBagConstraints(0, 0, 1, 1, 0.5, 0.5, 
      GridBagConstraints.NORTHWEST, GridBagConstraints.BOTH, 
      new Insets(5, 5, 5, 5), 0, 0)); 
    setVisible(true); 
}
