问题 I am not able to make this code work in AS3.0 ( Flash ) with Flex SDK 4.0 included. import mx.binding.utils.*; [Bindable] var myValue:int = 0; var cw:ChangeWatcher = BindingUtils.bindSetter(myValueChanged, this, "myValue"); addEventListener( Event.ENTER_FRAME , ef); function ef(e:Event):void { trace("hello",getTimer()); myValue = getTimer(); } function myValueChanged(o:Object):void { trace("myValue: " + myValue.toString()); } The output i get is : myValue: 0 hello 157 hello 168 hello 171

问题 I am trying to change the slider into buttonMode by using my_slider.buttonMode = true; but it doesn't shows handsymbol .Is there any other way to change the slider into buttonMode?. Thanks in advance. 回答1: i had the similar issue in one of my project. try this it will definitely work. // cmp_slider is component instance var mc = cmp_slider.getChildAt(1); // it is a drag button. mc.buttonMode = true; mc.useHandCursor = true; 回答2: my_slider.mouseChildren = false; my_slider.buttonMode = true;

问题 Is there anyway to download a file with the URLLoader and then save it to the disk without using filereference or anything that uses a dialog? This is what I have but isn't working: public function onDownloadComplete(e:Event):void { DownloaderProgress.label = 'Download Done'; var loader:URLLoader = URLLoader(e.target); var rtsFile:File = File.applicationStorageDirectory.resolvePath("RTS.zip"); var rtsStream:FileStream = new FileStream(); rtsStream.open(rtsFile, FileMode.WRITE); rtsStream

问题 If I load a bitmap using a loader in Flex, I can use the loaderInfo.bytesTotal to get the size, total bytes used, of a bitmap. If I create a bitmap in run time, how can I find out the size, the total bytes used, by that bitmap. Please advice. Thanks 回答1: var bitmapByteSize:int = bitmap.bitmapData.getPixels(bitmap.bitmapData.rect).length; That might do the trick. 回答2: I think a better solution than the one above would be: var bitmapByteSize:uint = bitmap.bitmapData.width * bitmap.bitmapData

问题 I have tried really hard to find an example showing how to play speex encoded audio in flash. I tried the following code - var connect_nc:NetConnection = new NetConnection(); connect_nc.connect(null); var stream_ns:NetStream = new NetStream(connect_nc); stream_ns.play("RE-Sample.m4a"); avaible at - http://www.adobe.com/devnet/flashplayer/articles/hd_video_flash_player _03.html I tested the above code with .flv videos and AAC encoded audio files and it works just fine. But when I try stream_ns

问题 Can any one tell me about what is the Difference between validateProperties() and invalidateProperties() ? 回答1: invalidateProperties: Marks a component so that its commitProperties() method gets called during a later screen update. Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text color and size, it would be wasteful to update the color immediately after

问题 I'm developing an application and because of certain design restrictions I have to do it in Flash. This application communicates with another one done in c++, but just because I need a couple strings, so I thought it would be easy to write them to a .txt file and parse it. But the only way I've found so far is adding a browse event handler and select the file manually. That's no good for me, I need the file to be read automatically given a path, something like: var data:ByteArray = fileRef['C

问题 So... I have a URL like www.example.com/stream/ I need to make any request to this url and get Http Rewspons header (like this one: HTTP/1.0 200 OK Content-type: video/x-flv Cache-Control: no-cache I do not need reponse body at all. After I get header need to emmidiatly close connection to that url (so stop to obtain data from it) How to do such thing (I use Flash builder) 回答1: Aparently, that's possible in AIR (I've never tried it): http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3
