FLEX4：如何添加子引发滚轮在AS [英] Flex4: How to add a child to spark Scroller in AS

问题描述

我要转换的以下code为ActionScript（MXML正常工作）：

 ＆LT; MX：面板标题=一些标题WIDTH =400HEIGHT =300＆GT;
  ＆所述氏：滚轮宽度=100％高度=100％/＆GT;
    ＆LT; MX：ColumnChart中的id =myChart属性=.../＆GT;
 

这不工作直截了当：

  setupChart（）; //设置myChart

VAR滚动：滚轮=新的滚轮（）;
scroll.percentWidth = 100;
scroll.percentHeight = 100;
scroll.viewport = myChart;
 

解决方案

添加组第一对我的作品

  setupChart（）;

VAR GRP：组=新集团（）;
grp.percentWidth = 100;
grp.percentHeight = 100;
grp.addElement（myChart）;

VAR滚动：滚轮=新的滚轮（）;
scroll.percentWidth = 100;
scroll.viewport = GRP;
 

I want to convert the following code to ActionScript (mxml works fine):

<mx:Panel title="Some Title" width="400" height="300">
  <s:Scroller width="100%" height="100%"/>
    <mx:ColumnChart id="myChart" attribute="..." />

This doesn't work straight forward:

setupChart(); //setup myChart

var scroll:Scroller = new Scroller();
scroll.percentWidth = 100;
scroll.percentHeight = 100;
scroll.viewport = myChart;

解决方案

adding a group first works for me

setupChart();

var grp:Group = new Group();
grp.percentWidth = 100;
grp.percentHeight = 100;
grp.addElement( myChart );

var scroll:Scroller = new Scroller();
scroll.percentWidth = 100;
scroll.viewport = grp;
