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，然后基于我需要创建一个新的SkinnableContainer并将其作为第一个子项添加的一些外部数据。这个子高度可以大于父容器。

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

运行时可能会达到相同的效果吗？

// ... 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

您始终可以将孩子置于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);

如何将滚动条添加到SkinnableContainer创建的运行时？
