如何将滚动条添加到SkinnableContainer创建的运行时？

Question

我创建了一个SkinnableContainer运行时，因为我想为它设置一些样式属性，然后基于一些外部数据，我需要创建一个新的SkinnableContainer并将其添加为第一个子项。这个孩子的身高可以大于父容器。

如何使用一些滚动条创建SkinnableContainer运行时？
I read in the documentation that I need to create a new Skin。

运行时可以达到相同的结果吗？

// ... in a container ... 

var father = new SkinnableContainer(); 
this.addElement(father); 

var child = new SkinnableContainer(); 
// ... some initialization... child is filled with some other elements from outside 

father.addElement(child); 

// ... now if child.height > father.height 
// I want to add a vertical scrollbar 

Answer 1

您可以随时把孩子放在Scroller控件中。

例如：

var father = new SkinnableContainer(); 
this.addElement(father); 

var scroller = new Scroller(); 
var child = new SkinnableContainer(); 
// ... some initialization... child is filled with some other elements from outside 

// scroller.addElement(child); // wrong because you cannot add element to a scroller 
scroller.viewport = child.contentGroup; // but you can set this to an IViewport 

father.addElement(scroller); 
father.addElement(child);
