Flex中如何利用top, bottom, left, right, horizontalCenter和vertical

接下来的例子演示了Flex中如何利用top, bottom, left, right, horizontalCenter和verticalCenter样式，放置某固定项目。
复制代码代码如下:<?xml version="1.0" encoding="utf-8"?>

 
    
        Form {
            paddingLeft: 0;
            paddingRight: 0;
            paddingTop: 0;
            paddingBottom: 0;
        }
    
 
    
        
    
 
    {canvas.width - image.width}
    {canvas.height - image.height}
