可以在不使用 MXML 的情况下使用 Flex 框架/组件吗? [英] Possible to use Flex Framework/Components without using MXML?

问题描述

是否可以在不使用 MXML 的情况下使用 Flex 框架和组件?我非常了解 ActionScript，并且不想仅仅为了在其中获得一些简单的 UI 而使用一些新的 XML 语言.任何人都可以提供一个由 .as 文件组成的示例，该文件可以被编译(理想情况下通过 FlashDevelop，虽然只是告诉如何使用 Flex SDK 来做到这一点也可以)并使用 Flex 框架?例如，只显示一个弹出警报的 Flex 按钮就完美了.

Is it possible to use the Flex Framework and Components, without using MXML? I know ActionScript pretty decently, and don't feel like messing around with some new XML language just to get some simple UI in there. Can anyone provide an example consisting of an .as file which can be compiled (ideally via FlashDevelop, though just telling how to do it with the Flex SDK is ok too) and uses the Flex Framework? For example, just showing a Flex button that pops open an Alert would be perfect.

如果不可能，有人可以提供一个最小的 MXML 文件来引导自定义 AS 类，然后该类可以访问 Flex SDK?

If it's not possible, can someone provide a minimal MXML file which will bootstrap a custom AS class which then has access to the Flex SDK?

推荐答案

我做了一个类似于 Borek 的简单引导程序(见下文).我很想去掉 mxml 文件，但如果我没有它，我就无法获得 Flex 附带的任何标准主题(haloclassic.swc 等).有人知道如何按照 Theo 的建议去做并且仍然应用标准主题吗?

I did a simple bootstrap similar to Borek (see below). I would love to get rid of the mxml file, but if I don't have it, I don't get any of the standard themes that come with Flex (haloclassic.swc, etc). Does anybody know how to do what Theo suggests and still have the standard themes applied?

这是我的简化引导方法:

Here's my simplified bootstrapping method:

main.mxml

<?xml version="1.0" encoding="utf-8"?>
<custom:ApplicationClass xmlns:custom="components.*"/>

ApplicationClass.as

ApplicationClass.as

package components {
    import mx.core.Application;
    import mx.events.FlexEvent;
    import flash.events.MouseEvent;
    import mx.controls.Alert;
    import mx.controls.Button;

    public class ApplicationClass extends Application {
        public function ApplicationClass () {
            addEventListener (FlexEvent.CREATION_COMPLETE, handleComplete);
        }
        private function handleComplete( event : FlexEvent ) : void {
            var button : Button = new Button();
            button.label = "My favorite button";
            button.styleName="halo"
            button.addEventListener(MouseEvent.CLICK, handleClick);
            addChild( button );
        }
        private function handleClick(e:MouseEvent):void {
            Alert.show("You clicked on the button!", "Clickity");
        }
    }
}

以下是在 Flex 4 中使用它的必要更新:

Here are the necessary updates to use it with Flex 4:

main.mxml

<?xml version="1.0" encoding="utf-8"?>
<local:MyApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:local="components.*" />

MyApplication.as

MyApplication.as

package components {
    import flash.events.MouseEvent;
    import mx.controls.Alert;
    import mx.events.FlexEvent;
    import spark.components.Application;
    import spark.components.Button;

    public class MyApplication extends Application {
        public function MyApplication() {
              addEventListener(FlexEvent.CREATION_COMPLETE, creationHandler);
        }
        private function creationHandler(e:FlexEvent):void {
            var button : Button = new Button();
            button.label = "My favorite button";
            button.styleName="halo"
            button.addEventListener(MouseEvent.CLICK, handleClick);
            addElement( button );
        }
        private function handleClick(e:MouseEvent):void {
            Alert.show("You clicked it!", "Clickity!");
        }
    }
}
