为什么我的弹出面板的子项出现在面板之外

Question

我正在使用 flex 4 弹出管理器弹出一个面板，但面板的子项没有留在面板内。但是当我关闭弹出窗口时，孩子们将被删除。

像这样：（抱歉我不能发布图片）

           ----------
           l________l
           l        l
  ..... please enterl
           l--------1

有人知道为什么吗？这是我的代码：

var forgotPopup:Panel = PopUpManager.createPopUp(this, forgottenForm, true) as Panel;
        PopUpManager.centerPopUp(forgotPopup);

这就是我弹出的内容：

<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" width="218" height="168" skinClass="PanelSkin" title="Reset Details">


    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <fx:Script>
        <![CDATA[

            import mx.controls.Alert;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;

            // Handle the close button and Cancel button.
            private function handleCloseEvent():void {
                PopUpManager.removePopUp(this);
            }

        ]]>
    </fx:Script>

    <mx:Form horizontalCenter="0" verticalCenter="0">
        <mx:FormHeading label="Please enter your e-mail address and your login details will be e-mailed to you"/>
        <mx:FormItem label="E-mail">
            <s:TextInput id="userInput" x="78" y="49"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <s:Button id="okButton" label="Submit" skinClass="ButtonSkin" />
            <s:Button id="cancelButton" label="Cancel" skinClass="ButtonSkin"/>
        </mx:FormItem>  
    </mx:Form>

</s:Panel>

对此的任何帮助都会很棒，谢谢。

尝试使用以下内容：

<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" width="218" height="168" skinClass="PanelSkin" title="Reset Details">


    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <fx:Script>
        <![CDATA[

            import mx.controls.Alert;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;

            // Handle the close button and Cancel button.
            private function handleCloseEvent():void {
                PopUpManager.removePopUp(this);
            }

        ]]>
    </fx:Script>

    <mx:Form left="10" right="10" top="10" bottom="10">
        <mx:FormHeading label="Please enter your e-mail address and your login details will be e-mailed to you"/>
        <mx:FormItem label="E-mail">
            <s:TextInput id="userInput" x="78" y="49"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <s:Button id="okButton" label="Submit" skinClass="ButtonSkin" />
            <s:Button id="cancelButton" label="Cancel" skinClass="ButtonSkin"/>
        </mx:FormItem>  
    </mx:Form>

</s:Panel>

如果您需要将标题文字换行，则应拒绝标准 FormHeading 并将其替换为 Label：

<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" width="218" height="168" skinClass="PanelSkin" title="Reset Details">


    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <fx:Script>
        <![CDATA[

            import mx.controls.Alert;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;

            // Handle the close button and Cancel button.
            private function handleCloseEvent():void {
                PopUpManager.removePopUp(this);
            }

        ]]>
    </fx:Script>

    <mx:Form left="10" right="10" top="10" bottom="10">
        <s:Label width="100%" text="Please enter your e-mail address and your login details will be e-mailed to you" fontWeight="bold" />
        <mx:FormItem label="E-mail">
            <s:TextInput id="userInput" x="78" y="49"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <s:Button id="okButton" label="Submit" skinClass="ButtonSkin" />
            <s:Button id="cancelButton" label="Cancel" skinClass="ButtonSkin"/>
        </mx:FormItem>  
    </mx:Form>

</s:Panel>

但最好的方法是切换到 Spark Form 其中自 Flex 起可用4.5.

请避开X和Y位置
这也可能导致对象位置。
