Flex 4/ActionScript 3 中 ComboBox 的方法 setSelectedIndex：是否有当前文档？

Question

我一直在查看 Adobe 的 the spark ComboBox 文档，但找不到方法：

setSelectedIndex(value:int, dispatchChangeEvent:Boolean = false, changeCaret:Boolean = true):void

我知道这个函数存在，因为我的代码使用了它。我正在使用 Flex SDK 4.14.1。当我转到 ComboBox.as 源文件时，我发现功能很好：

/**
 *  @copy spark.components.supportClasses.ListBase#setSelectedIndex()
 *  
 *  @langversion 3.0
 *  @playerversion Flash 11.1
 *  @playerversion AIR 3.4
 *  @productversion Flex 4.10
 */
override public function setSelectedIndex(value:int, dispatchChangeEvent:Boolean = false, changeCaret:Boolean = true):void
{
    // It is possible that the label display changed but the selection didn't.  If this is
    // the case, the label has to be updated since the setSelectedIndex code will short-circuit
    // and not commit the selection.
    // An example is if the label is deleted and then the first item is chosen from the
    // dropdown, the selectedIndex is still 0.
    if (userTypedIntoText && value == selectedIndex)
        updateLabelDisplay();

    super.setSelectedIndex(value, dispatchChangeEvent, changeCaret);
}

我还上了继承树（DropDownListBase -> List -> ListBase 等）和 ComboBox 继承的类的 none 有关于 setSelectedIndex 的文档。

我能找到的唯一文档是保存在 ZengRong's blog 上的旧版本 (Flex 4.10)。

还支持setSelectedIndex方法吗？我可以在其他任何地方查找文档吗？

该版本的 Flex 来自 open-source Apache version，Adobe 不再 maintains/develops Flex：

http://flex.apache.org/asdoc/spark/components/ComboBox.html

setSelectedIndex () method

override public function setSelectedIndex(value:int, dispatchChangeEvent:Boolean = false, changeCaret:Boolean = true):void

The rowIndex is the index in the data provider of the item containing the selected cell.

Parameters

value:int — The 0-based row index of the cell.

dispatchChangeEvent:Boolean (default = false) — if true, the component will dispatch a "change" event if the rowIndex has changed. Otherwise, it will dispatch a "valueCommit" event.

changeCaret:Boolean (default = true) — if true, the caret will be set to the selectedIndex as a side-effect of calling this method. If false, caretIndex won't change.
