问题 So I have a Flex bar chart that resizes dynamically, and if I have only a few items, the height shrinks and the horizontal axis and label shrink along with it. If the height of the chart is small enough, the label shrink down to practically nothing. How can I enforce a minimum height for the axis itself? Or even a minimum font size for the labels? I've tried setting the font size on the axis renderer and the axis label renderer and Flex still wants to resize the labels how it wants. 回答1: put

问题 According to this document from Adobe Create and apply view states is <s:State/> a state object. How to create the view states in code-behind ActionScript class? 回答1: I have found a simple solution, and I don't have to declare the states using skinning architecture.

问题 I don't understand why when we change data on dataprovider , all the itemRenderers of the impacted column are called ? Here is a little example of my problem : application : <?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="application1_creationCompleteHandler(event)"> <fx:Script> <![CDATA[ import mx.collections

问题 I was just curious about the password mode display of the TextInput control in flex. The control displays asterisks instead of the characters themselves when the 'displayAsPassword' is set to true. Quoting the documentation, displayAsPassword If true, the field does not display entered text, instead, each text character entered into the control appears as the character "*". So, is there any way to change this displayed character, unless of course creating a custom component or extending the

问题 My Flex/AS3 web application accesses a database and retrieves text containing \n for newline character. Otherwise the text looks like normal text. Is there a way to convert the \n into paragraph tags that I can insert into an spark TextFlow? For example, my only experience with TLF is in writing mxml code such as follows: <s:RichEditableText width="100%" height="100%" textAlign="left" paddingTop="0" paragraphSpaceAfter="0.3" editable="false"> <s:textFlow> <s:TextFlow> <s:p fontWeight="bold"

All I want to do is to name the three fields with a different name for accessibility so the user knows what to do. I tried to just use declaration to define the accessibility properties but it seems like it will always only speak out one name of the button. Thus, I took another approach and tried to create

问题 For the past few hours I have been trying to clone an image in Flex (using the Spark Components, but also trying to convert between Bitmap and BitmapImage). What I am trying exactly is to create a simple painting application which keeps track of each Brush-Stroke. As soon as the Image on the Canvas has changed, it is to be cloned and then the clone is to be put into the History-Panel on the bottom of the application. Things I have tried include: Using ObjectUtils.clone(Object) Creating
