问题 At first glance, the Repeater control looks extremely powerful, but now I'm having second thoughts. Problem at hand: Adding Event Listeners to the children Repeater object is bound to and iterates through an ArrayCollection creating new Vbox children for each item. Now for each child, the Repeater object will fire off a "repeat" event, where I'm tempted to add the eventlistener (for mouse events). No problems so far, but, what happens when the ArrayCollection changes, how should I remove the

问题 My question is, that how can I get the node in witch I want to insert: I.e <folder id="1"> <folder id="4"> <folder id="5"></folder> </folder> </folder> <folder id="2"> <file id="4"/> </folder> <folder id="3"> </folder> I want to get folder with id = 4, but that can be on any level. If folders couldn't contain one another than it would be like this myNode = xml.folder.(@id == 4). 回答1: Use the .. operator, it looks for all the nodes with given name and it doesn't matter how deep they are. For

问题 I want to extend the DataGrid component so that there is a (read-only) column for the row number like you see in spreadsheets. I came across this article http://www.cflex.net/showFileDetails.cfm?ObjectID=735 but it depends on the data being unique for each row so that it can index into the array. If the data is not unique (like for an empty grid) it doesn't work. How can I implement that? 回答1: This worked for me: <mx:Label xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[

问题 Is there a way to allow a flex application to have a dynamic height while embedded in an HTML wrapper? I want the Flex application to grow in height in a way that it will not cause vertical scroll bars. 回答1: The best way should be overriding the Application's measure method like: private var _lastMeasuredHeight:int; override protected function measure():void { super.measure(); if (measuredHeight != _lastMeasuredHeight) { _lastMeasuredHeight = measuredHeight; if (ExternalInterface.available) {

问题 I am not using FlexBuilder, I'm using the free Flex SDK with TextMate. I'm having some trouble figuring out what this FlexBuilder process actually does behind all the nice dialogs and things, so that I can do the same thing by tweaking whatever the relevant file is, but Googling just points me at similar instructions telling me to use FlexBuilder. Anyone able to point me in the right direction? 回答1: mxmlc considers a swc a library (it's actually a zip file that you can examine) so you'll want

问题 I'm trying to change the font color of a row in a datagrid if a certain word is found in a datafield. Is there a simple, inline way to do this? Thanks 回答1: You can override your DataGrid 's drawRowBackground method, and check whether it needs custom background or not. If so, pass the new background color to the super call of this method: protected override function drawRowBackground(s:Sprite, rowIndex:int, y:Number, height:Number, color:uint, dataIndex:int):void { if ((dataProvider[dataIndex]

问题 HI, i want to build a datagrid which will have a dynamic height value because the number of rows will always be different. I also want to communicate the height back to the component holiding it so that it also grows with the datagrid. Can anyone help me out on the best way to create such a dynamic datagrid. Thanks 回答1: The DataGrid's height is controlled by its rowCount property. If you want your DataGrid to always be exactly high enough to show all the contained elements (and, for example,

问题 I'd like to know whether it's possible to easily detect (on the server side) when Flex clients disconnect from a BlazeDS destination please? My scenario is simply that I'd like to try and use this to figure out how long each of my clients are connected for each session. I need to be able to differentiate between clients as well (ie so not just counting the number of currently connected clients which I see in ds-console). Whilst I could program in a "I'm now logging out" process in my clients,

问题 I have a function that restores all of the default settings of my application. This process can take a bit of time, so I would like to implement a "Please wait..." modal popup to let the user know that everything is alright and the program hasn't frozen. Once the function completes its task, I'd like for it to remove the message, and resume normal behavior. alt text http://www.freeimagehosting.net/uploads/c5906da30c.jpg 回答1: On start: var waitingpopup:TitleWindow = new TitleWindow()
