问题 I'm using Flash Builder and created a spark-application Flex project that will stream video from the local camera. If I use mx.controls.VideoDisplay ; there is no problem since it has attachCamera(camera) method. But Spark's VideoDisplay component does not have that method. I know I can use mx controls inside a Spark app but I want to know: What is the real difference between spark.components.VideoDisplay and mx.controls.VideoDisplay ? How do I attach camera to spark.components.VideoDisplay ?

问题 Looks like I can use components for both <mx:> or <s:> . So, which has more advantages? 回答1: As other posters have mentioned, the spark (s:) namespace refers to the new components introduced with Flex 4, while the halo/mx (mx:) namespace refers to the older components. They can be used together, which is necessary since there are not spark equivalents for all of the mx components (notable omissions are DataGrid, Tree, DividedBox, among others.) Some of the motivations for the new spark

问题 I am just getting started with flex and am using the SDK (not Flex Builder).

问题 I just started working with Flex. I know it's pathetic but it's a long story. Now, the problem I am facing is that I have a list component which has a dataprovider on it.

Is it possible to do this using a single ChangeWatcher? Specifically, can the following code be modified so that it uses only one ChangeWatcher and if so how? <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com

问题 I'm working with Flex4 and I'm trying to skin a form (add a background and a border to it, etc.) I'm trying to do it the Flex 4 way with skinClass="" <mx:Form skinClass="skins.MyFormSkin" /> but it's not accepting skinClass as a property. How should I do it such that I'm still adhering to the best practices in Flex 4 (decoupling visuals from logic)? 回答1: skinClass only works on spark components, which have tags starting with <s: 回答2: To elaborate on Qz's response: mx:Form is not a Flex 4

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I`m new in flex and could anyone help me?
