Flex HSlider工具提示数组填充

Question

我希望能够通过Web服务为HSlider填充工具提示数组。

下面是我的代码，我在这里所做的只是在arrayValues数组的init（）函数中填充anotherArray来测试。

但是，当我启动应用程序anotherArray只包含“空”，而不是其余的数据。

任何想法？

Answer 1

Flex的用于与所述阵列型数据绑定支持是有限的。当您调用Array.push（）时，HSlider不会收到更改事件。几乎在所有情况下，我都推荐使用ArrayCollection而不是Array。与应用程序中所有UIComponents的复杂性相比，开销实际上可以忽略不计。

[Bindable] 
public var numResults:int = 0; 

// array to test slider 

[Bindable] // you miss this line 
var arrayValues:Array = ["null","January '08", "February '08", "March '08", 
      "April '08", "May '08", "June '08", "July '08", 
      "August '08", "September '08", "October '08", 
      "November '08", "December '08"]; 

[Bindable] 
public var anotherArray:Array = new Array();
