flex4

问题 I've got the latest Beta of Adobe Flash Builder 4. I want to use a <s:List> component, and specify the dataProvider as being an XML file. However, after loads of research (including looking at doc links off labs.adobe.com), I still can't figure out how to do it. The XML file will look something like this: <?xml version="1.0" encoding="ISO-8859-1"?> <imageList> <image location="path/to/file1.jpg" /> <image location="path/to/file2.jpg" /> <image location="path/to/file3.jpg" /> </imageList> 回答1:

问题 I need something like jQuery UI's Sortable in Adobe Flex.

问题 has anyone been able to use Workers in AIR Application built with Flex 4.9.1 and AIR 3.7?

The compiler compiles, I get the info-text in the console, but neither my window opens nor my does any of my events get fired. Ideas anyone :) ? 回答1: Quite simple solution. Simply add -swf-version=XX //XX must be >=17 as a

问题 I have this IconButton: Class package extra { import spark.components.Button; import spark.primitives.BitmapImage; public class IconButton extends Button { private var _icon:Class; [SkinPart(required="false")] public var iconElement:BitmapImage; public function get icon():Class { return _icon; } public function set icon(val:Class):void { _icon = val; if (iconElement != null) { iconElement.source = _icon; } } override protected function partAdded(partName:String, instance:Object):void { super

问题 i have a sequence of buttons and each button has its own icon. I was wondering if I have to create a Spark skin file for each button in order to assign its icon. thanks 回答1: You don't have to create separate skins, you could make 1 skin and 1 class (that extends Button ) with a property you can set to determine which icon to draw based on the button. You can extend the button class like this package com.components { import spark.components.Button; //icons [Style(name="iconImg",type="*")]

问题 I've had two issues when working with TextArea and TextInput on mobile components I don't know how to solve. The first is that the TextArea text does not position correctly and the second is that it overlaps other components. The issues occur when the TextArea is in a Scroller (or the soft keyboard activates and moves the TextArea position). You can see this if you add the code below to a mobile Application: <s:Scroller width="100%" height="100%" top="100" bottom="100"> <s:VGroup width="50%">

问题 I have the following panel component called AdvancedPanel with controlBarContent: <!-- AdvancedPanel.mxml --> <s:Panel> <s:states> <s:State name="normal" /> <s:State name="edit" /> </s:states> <s:controlBarContent> <s:Button includeIn="edit" label="Show in edit" /> <s:Button label="Go to edit" click="{currentState='edit'}" /> </s:controlBarContent> </s:Panel> I created a second panel, called CustomAdvancedPanel based on the AdvancedPanel since I don't want to redeclare the controlBarContent <
