NavigatorContent中组件多了之后如何出现纵向滚动条?
<s:NavigatorContent label="Tab 1" >
<s:layout>
<s:BasicLayout />
</s:layout>
<s:Rect width="20" height="20" top="0" left="0" >
<s:stroke>
<s:SolidColorStroke weight="1" color="0x880000" />
</s:stroke>
<s:fill>
<s:SolidColor alpha="1" color="0x008800" />
</s:fill>
</s:Rect>
<s:Button label="Button" top="0" right="0" />
<s:CheckBox label="CheckBox" bottom="0" left="0" />
<s:TextInput text="TextInput" bottom="0" right="0" width="60" />
</s:NavigatorContent>
