问题 I'm working on my first ever AIR application with flashbuilder - just so you know. I've bound a mx:DataGrid component to a DataProvider which is a mx:HTTPService fetching an xml file with items. To keep the data up to data I'm polling the webservice on a given interval. My problem is that I loose the currently selected item in my DataGrid when the data is updated. I've tried to save the DataGrid.selectedIndex and set when the data is updated, but I'm not sure when to do it?! The closest I've

问题 I'm drawing a path in Flex using Spark:Path. I want to subtract a circle shape from this path, as in the following image: (The path is black and wide) Any ideas?

问题 How much of an impact will migrating to Flex 4 have on our code base? We have about 40k LOC written in Flex 3. I'm hoping that there are no breaking changes in the Flex SDK, and that we can smoothly transition to the new features of Flex 4 while minimizing any disruption. From what I've read Adobe is developing a new set of GUI components called 'Spark' but I'm hoping our existing stuff can co-exist with the new components. 回答1: Spark and MX components can co-exist within the same application

问题 As the new Flex SDK 4.5 has become a stable release, I want to upgrade my apps to the new SDK. But without losing compilation with SDK 4.0 with which they are working perfectly well. I used Flash Builder 4.0 to build them.

You have a few options: Use a build tool such

问题 I'm building a video player using Flash CS4 (hereby referred to as "Flash") to create the graphic symbols and compiling and debugging with Flash Builder 4 ("FB4"). Here are the steps I take in my current workflow: --Create the graphic symbols in Flash. I've created a few different symbols for the player, but I'll focus on just the play/pause button ("ppbutton") here. --In the Library panel, I go to the ppbutton symbol's Linkage properties and link to a class named assets.PlayPauseButtonAsset

问题 I worked on a flex application 6-7 months back. We used flex 3.5 sdk. Now we are upgrading our flex app with flex sdk 4/4.1 I am still new to flex development and I have a very basic question related to namespace. I have seen three different namespaces in flex sample applications. What is the purpose of having three diff namespaces? When do I use each of them ? xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" Thanks
