swing常用的布局

常用的布局有

1.流布局

2.邊界布局

3.網格布局

4.卡片布局

5.網格包布局

測試**：

public class testone 

/*** 流布局
* @param frame
*/public void testflowlayout(jframe frame)
} /**
* 邊框布局
* @param frame
*/public void testborderlayout(jframe frame)
frame.add(button[0],"north");
frame.add(button[1],"west");
frame.add(button[2],"east");
frame.add(button[3],"south");
frame.add(button[4],"center");
} /**
* 網格布局
* @param frame
*/public void testgridlayout(jframe frame)
} /**
* 卡片布局
* @param frame
*/public void testcardlayout(jframe frame)
pan2.add(pan3, "1");
jlabel lb1=new jlabel("panel 1");
pan3.add(lb1);
pan2.add(pan4, "2");
jlabel lb2=new jlabel("panel 2");
pan4.add(lb2);
pan2.add(pan5, "3");
jlabel lb3=new jlabel("panel 3");
pan5.add(lb3);
button[0].addactionlistener(new actionlistener() 
});button[1].addactionlistener(new actionlistener() 
});button[2].addactionlistener(new actionlistener() 
});} /**
* 網格包布局
*/public void testgridbaglayout(jframe frame)
c.fill = gridbagconstraints.horizontal;
c.gridx = 0;
c.gridy = 0;
// c.weightx = 0.2;//水平布局佔的權重
frame.add(button[0], c);
c.fill = gridbagconstraints.horizontal;
c.weightx = 0.8;
c.gridx = 1;
c.gridy = 0;
frame.add(button[1], c);
c.fill = gridbagconstraints.horizontal;
c.weightx = 0.2;
c.gridx = 2;
c.gridy = 0;
frame.add(button[2], c);
c.fill = gridbagconstraints.horizontal;
c.ipady = 80; // make this component tall
c.weightx = 1;
c.gridwidth = 3;
c.gridx = 0;
c.gridy = 1;
frame.add(button[3], c);
c.fill = gridbagconstraints.horizontal;
c.weighty = 1.0;
c.weightx=1;
c.anchor = gridbagconstraints.page_end; 
c.gridx = 1; 
c.gridwidth = 1; 
c.gridy = 2; 
frame.add(button[4], c);
