What I have so far works fine, but I'd like stylize it to where the the row of thumbnails, when individually clicked, displays the larger image and other information. <?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/flex/mx" minWidth="955" minHeight="600" creationComplete="main()" backgroundColor="#FFFFFF"

问题 Is there a way to make the elements of a VBox smoothly move to their new positions when a new element is inserted or removed? I actually need only to make them move smoothly when I remove an element.

问题 I'm looking for resources on making an interactive charting component in Adobe Flash without use of Flex (or, minimal use). That is, starting "from scratch" with Flash and ActionScript 3.0. Is there recommended reading? Perhaps a good recent book on the subject, or a detailed blog article, or an open source project to look at? I'm interested in the development process, and specific design patterns (for example, extending Sprite as the logical base class for your component). Thanks! ♥ 回答1: The

问题 What is the difference between using HTTPService and URLRequest for requesting your data from a flex page to servlet 回答1: URLRequest is the Request Object that contains the URL to load, the post parameters, etc. Usually it is used with more basic loader types than HTTPService, like URLLoader. HTTPService takes the URL directly as one of its properties, so it doesn't need a URLRequest. Technically, you could use a URLRequest to provide the rest of the "payload," since it is an Object and the

问题 I have two tables: Person {pID, pName, deptID} and Departments {deptID,deptName} An SQL statement like this gets me the name of a person and the department name: SELECT pName, departments.deptName FROM people INNER JOIN people.deptID = departments.deptID; The above works fine. I have a Flex DropDownList that is populated with deptNames. When I click the submit button, I am able to obtain the ID of the selected department without problem: protected function button_clickHandler(event:MouseEvent

问题 I'm writing a small application for myself and instead of using a database I'd like to just use Excel to store the small amount of data I have on my local file system. I want to be able to load that data without having to use the typical FileReference browse() method as it would just be annoying to do every time I use the application. The code below seems to find the file fine as the file.exists method below and most of the other attributes seem to be correct but the file.data is always null.

问题 I have a project in which i need to pop up an alert to the user before a combobox value is changed. This feature is to allow the user to stay in current state if modifications were not saved. Meaning that the user will be able to cancel the change. I have sub classed ComboBox and tried to hook on ITEM_CLICK of ComboBox.dropdown but this event is triggered after the value is changed. Also, I've tried MOUSE_CLICK ans MOUSE_DOWN but without success. In my code, I have added a "preChange" event

问题 I was wondering if there is any way you hide a particular button in a ButtonBar. According to this answer (and the link provided in the second answer) Disable individual buttons in a buttonbar I need to use the getChildAt method of the ButtonBar, but when I do that I get the custom skin object and not the Button object. I was wondering how I could get access to the Button object. Thanks! 回答1: Under the assumption that all buttons in your button bar will be rendered at the same time and you

问题 How to be able to start up same Adobe Air applications multiple times? How to make it to my app? 回答1: Multiple instances are not supported, but you can work around it. If you want the feature to support being run multiple times, you can respond to the InvokeEvent.INVOKE event dispatched by the NativeApplication. You can then open a new window and make it appear that the application is running multiple times. Alternatively, if you are simply trying to run the application multiple times to test
