我有一个弹出对话框，它是一个 mx:TitleWindow。但是，对话框的渲染高度太大，请参阅底部的空白。将高度降低 x 像素似乎没有效果。如何正确调整尺寸？

<mx:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"

     xmlns:mx="library://ns.adobe.com/flex/mx" width="356" height="322"
     layout="vertical" showCloseButton="true" close="cancel(event)"
     title="Add User" creationComplete="usernameTF.setFocus();"
     hasFocusableChildren="true">

将高度降低 x 像素

你要降低哪个高度？ 

<mx:TitleWindow 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="356" height="322"
     layout="vertical" showCloseButton="true" close="cancel(event)"
     title="Add User" creationComplete="usernameTF.setFocus();"
     hasFocusableChildren="true">


<s:Form height="280" defaultButton="{apply}">

在您显示的代码中，我希望框的高度为 322。形式为 280；在底部留下约 42 像素的空白。
