导读:使用SDK 4.1,我能够从自定义皮肤访问自定义按钮组件的自定义属性.我目前正在工作的项目需要SDK 4.5,我无法访问这些属性.这是一个例子: 自定义按钮组件 ?xml version="1.0" encoding="utf-8"?s:ButtonBase xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s
使用SDK 4.1,我能够从自定义皮肤访问自定义按钮组件的自定义属性.我目前正在工作的项目需要SDK 4.5,我无法访问这些属性.这是一个例子:
自定义按钮组件 <?xml version="1.0" encoding="utf-8"?> <s:ButtonBase xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" skinClass="components.skins.ButtonIcon_Skin" > <fx:Declarations> <fx:String id="iconCustom" /> </fx:Declarations> </s:ButtonBase> 自定义按钮皮肤 <?xml version="1.0" encoding="utf-8"?> <s:SparkButtonSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:fb="http://ns.adobe.com/flashbuilder/2009" minWidth="21" minHeight="21" alpha.disabled="0.5"> <fx:Metadata>[HostComponent("components.ButtonIcon")]</fx:Metadata> ... <s:Label id="test" {hostComponent.iconCustom}" horizontalCenter="0" bottom="10" /> </s:SparkButtonSkin> 代码提示显示了hostComponent.iconCustom,但随后给出了错误: Access of possibly undefined property iconCustom through a reference with static type spark.components.supportClasses:ButtonBase. ButtonIcon_Skin.mxml 解决方法
只需用常规皮肤替换SparkButtonSkin,你就可以了:
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <fx:Metadata> [HostComponent("components.ButtonIcon")] </fx:Metadata> <s:states> <s:State name="disabled" /> <s:State name="down" /> <s:State name="over" /> <s:State name="up" /> </s:states> <s:Label text="test {hostComponent.iconCustom}" horizontalCenter="0" bottom="10" /> </s:Skin> (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
