Flex 4.6 hostComponent不再適用？

hostComponent似乎已停止工作，因爲它以前用過。如果我創建一個自定義組件，可以讓我們說SkinnableContainer並應用默認皮膚，我無法看到皮膚的Bindable /公共變量的提示。下面的代碼來說明。Flex 4.6 hostComponent不再適用？

我在這裏錯過了什麼？其他組件/皮膚似乎也會發生這種情況。我正在使用最新的Flash Builder（4.6）。

如果您想要獲取代碼提示，您的皮膚中的[[HostComponent（「spark.components.SkinnableContainer」）]指令需要指定自定義組件（例如'MyComponent'），而不僅僅是'SkinnableContainer'在變數和方法上。這只是你問題中的一個錯字嗎？ – merv

沒有錯字，就是這麼簡單:)我想我上次使用hostComponent我手工編碼它...爲什麼Flash Builder不添加自定義hostComponent我想知道？是否有任何使用「[HostComponent（」spark.components.SkinnableContainer「）]」？感謝您的回答，請將其添加，我會接受！ :) – DominicM

爲了使Flash Builder能夠爲您提供代碼提示，以便爲公共方法和屬性一個自定義組件，自定義組件需要在皮膚內的HostComponent metadata directive中指定。目前，您提供的皮膚代碼有：

[HostComponent("spark.components.SkinnableContainer")]

嘗試將其更改爲您的自定義組件，例如。 com.mydomain.MyComponent。
