高端大气上档次的新型界面

2016.11.05

前面我们学习java的Swingj界面时，出来的框都是固定的，并且不是很好看，如果我们想改变一下，那应该怎么办呢？

查找资料发现是可以做到的。

用setUndecorated可以去掉窗口的修饰

import java.awt.Button;
import java.awt.Shape;
import java.awt.geom.Area;
import java.awt.geom.Ellipse2D;
import java.awt.geom.Rectangle2D;
import javax.swing.JFrame;
import com.sun.awt.AWTUtilities;

public class MyShape {
public void specialUI(){
	JFrame jf = new JFrame();
	jf.setSize(400,400);
	//加按钮
	Button bu=new Button("登录");
	jf.setUndecorated(true);//去掉窗体的修饰
	jf.add(bu);
	
	Shape elipes=new Ellipse2D.Float(0,0,300,300);//圆
	Shape rect =new Rectangle2D.Double(0,0,100,100);//矩形
	Area ar1=new Area(elipes);
	Area ar2=new Area(rect);	
	//两个图形合在一起
   ar1.add(ar2);
   /*
    * When using com.sun.awt.AWTUtilities, Eclipse gives a error:
- Access restriction: The method setWindowOpacity(Window, float) from the type AWTUtilities is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar
- Access restriction: The type AWTUtilities is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar
You can fix it like this:
Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API ->
Forbidden reference -> change "error" to "ignore" 
    */
    AWTUtilities.setWindowShape(jf,ar1);//设置窗体的形状
	jf.setVisible(true);	
}
	
	public static void main(String[] args) {
		MyShape ud=new MyShape();
		 ud.specialUI();

	}

}

 这样出来的结果如下：

   
另外的代码表示：

public class MyShape extends JFrame {  
    public static void main(String[] args) {  
    SwingUtilities.invokeLater(new Runnable() {  
        @Override  
        public void run() {  
            JFrame.setDefaultLookAndFeelDecorated(true);  
            MyShape frame = new MyShape();  
        frame.setSize(new Dimension(200, 300));  
        /** 设置圆角 */  
        AWTUtilities.setWindowShape(frame, new RoundRectangle2D.Double(  
            0.0D, 0.0D, frame.getWidth(), frame.getHeight(), 26.0D,  
            26.0D));  
        frame.setVisible(true);  
        }  
  
    });  
    }  
} 

   路漫漫其修远兮 吾将上下而求索,如果想要做的更好一点,还需付出大量时间。
