flex4

问题 This must be a simple problem, but I can't get my head around it. I have a resizable title window. Inside I just want a VGroup to hold the contents of the form and an HGroup to have a few buttons at the bottom. Very standard stuff. <!-- Content --> <s:VGroup id="content" height="340" width="100%"> ...more stuff in here... </s:VGroup> <!-- Buttons --> <s:HGroup id="buttonGroup" width="100%"> ...buttons in here... </s:HGroup> Horizonal resizing works fine. However, I want it to behave such that

问题 I have a spark TabBar and I want to hide and show some elements of it from an external user input (namely a checkbox check) I am having trouble changing the tabs visibility. They are currently always shown. Does anyone have any idea? I have seen a getTabAt on the mx TabBar but the look of the tab is important and the requirement is for it to look like a tab bar rather than a button bar. My code for the tabs and for hiding and showing is below: <fx:Script> <![CDATA[ import mx.containers.VBox;

问题 I have a line chart with a column chart as a secondary series. When I roll over the line, the datatips appear. However, if I move the mouse to a spot where a column appears while still on the line, the data tip item appears for the line AND the column. How do I get it so that I only show datatips for the line but not the column? <mx:AreaChart id="areachart" dataProvider="{data}" showDataTips="true" > <mx:series> <mx:AreaSeries id="areaSeries" xField="date" yField="volume" > </mx:AreaSeries>

问题 I have a custom Flex 4.5 component (to be used in a List) - Game.mxml (represents a clickable playing table in a card game): <?xml version="1.0" encoding="utf-8"?> <s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:comps="*" width="160" height="160" autoDrawBackground="false" creationComplete="init(event)"> <fx:Metadata> [Event(name="pref_event", type="PrefEvent")] </fx:Metadata> <fx:Script> <!

问题 I use a TextInput component of Flex 4.5 to enter some text in English. I use the restrict attribute to ... restrict the keyboard input to characters a-zA-Z only. The problem is that if i copy/paste a word in another language, i can then paste it into the TextInput component. Is there a way to avoid that? If no, how can i validate the input against a specified language? I found out that the unicode set of Chinese+ language symbols is \u4E00 to \u9FFF. So i write the following: var chRE:RegExp

问题 I have two states. When I switch from OFF to A, it resizes correctly, but when I switch from A back to OFF it happens without the smooth resize transition. What am I doing wrong? Here's my code: <?xml version="1.0" encoding="utf-8"?> <s:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"> <fx:Script> <![CDATA[ protected function butA_changeHandler(e:Event):void { if ((e.target as ToggleButton).selected) { this
