问题 I have a Flex application,I am loading a JSON file with more than 40,000 items.

问题 When I execute the following code: var urlRequest:URLRequest = new URLRequest("http://somehost/with/some/path?andsomequerystring=true"); urlRequest.method = 'POST'; var urlLoader:URLLoader = new URLLoader(urlRequest); urlLoader.addEventListener(Event.COMPLETE, function(event:Event):void{ trace('sweet'); }); It turns my explicit POST request to GET due to the presence of the querystring. If I remove the querystring (and serialize as part of the POST body), it successfully makes the

问题 I'm pulling xml data to determine which columns are visible, and the widths of each column. My datagrid's width can change sinces its on one side of a HDividedBox. The visibility part works, but setting the width is causing headaches. Heres the code: for(loop through column data retrieve from XML) { newData[i] = dg.columns[Number(columnsOrder[i]) - 1]; newData[i].visible = (Number(columnsVisibility[i]) == 1); newData[i].width = Number(columnsWidth[i]); trace(newData[i].headerText + " w:" +

问题 I have a DropDownList inside the itemEditor of my DataGrid. There are enough items in the DropDownList to justify scrollbars. You can see the scrollbars, and the mousewheel works fine. If you move the mouse over the scrollbars, they'll change appearance fine (mouseover is working). If you click on them, the DropDownList closes as if you'd clicked elsewhere in the data grid. There's a comment on the Adobe Forums that describe the same problem, but it is fairly old and has not been answered. I

问题 I get a Date of my database and I need to show it as a String. So in Flex I do this: public static function dateToString(cDate:Date):String { return cDate.date.toString()+"."+ cDate.month.toString()+"."+ cDate.fullYear.toString()+" "+ cDate.hours.toString()+":"+ cDate.minutes.toString()+":"+ cDate.seconds.toString(); } But I get for example the result: 13.7.2010 0:0:15 How can I fill the day, month, hours, minutes, seconds with padded 0? And, I go back from String to Date with: DateField

问题 I need the name of the current logged in user in my Air/Flex application. The application will only be deployed on Windows machines. I think I could attain this by regexing the User directory, but am open to other ways. 回答1: There's a couple of small cleanups you can make... package { import flash.filesystem.File; public class UserUtil { public static function get currentOSUser():String { var userDir:String = File.userDirectory.nativePath; var userName:String = userDir.substr(userDir

问题 I'm working on some Flex spike in my company. We are basically evaluating different scenarios etc. What solution would you recommend for embedding Flex components into Java app? Flex <-> Java communication is not (yet...) an issue, just embedding swf into JFrame. 回答1: I've done it with EasyJCom. It's pretty straight forward as long as you're using one of the standard Java windowing libraries (Swing, awt). You can see an example (From the EZJCom site) here: http://www.ezjcom.com/FlashTest.java

问题 I have an image (mx) and i want to get the uint of the pixel that was clicked. Any ideas? 回答1: Here's an even simpler implementation. All you do is take a snapshot of the stage using the draw() method of bitmapData, then use getPixel() on the pixel under the mouse. The advantage of this is that you can sample anything that's been drawn to the stage, not just a given bitmap. import flash.display.Bitmap; import flash.display.BitmapData; import flash.events.*; stage.addEventListener(MouseEvent
