如何將滾動條添加到SkinnableContainer創建的運行時？

Question

我創建了一個SkinnableContainer運行時，因爲我想爲它設置一些樣式屬性，然後基於一些外部數據，我需要創建一個新的SkinnableContainer並將其添加爲第一個子項。這個孩子的身高可以大於父容器。

如何使用一些滾動條創建SkinnableContainer運行時？
I read in the documentation that I need to create a new Skin。

運行時可以達到相同的結果嗎？

// ... 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

您可以隨時把孩子放在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);
