问题 I'm trying to create a MXML component based on the spark Panel and I would like to add an image on the right end of the title bar, so that the panel will have a text on the title bar and a small image at the right end. I'm using a skin to define the colors, background fill etc. But how do I add this image at the right end of the title bar? I would like to make that image cutomizable so that when the component is inserted, either the default image is used or a new image can be provided. Please

问题 I've got this issue: I've got a dataGrid where whenever I set the column to not be resizable, the width gets messed up; works: var myCol:DataGridColumn = new DataGridColumn("Title"); myCol.width = 180; doesn't work (width is about 40pixels): var myCol:DataGridColumn = new DataGridColumn("Title"); myCol.width = 180; myCol.resizable = false; has anyone come across this or know why this is happening? I'm ready to just create my own dataGrid class now... 回答1: One thing that has helped us in the

问题 I have a Flex 4 app that now and then needs to do a lot of processing, which causes a user to wait a few seconds for it to complete. I know Flex allows one to set and remove busy cursors via the cursor manager. I'm using it as follows: CursorManager.setBusyCursor(); // add busy cursor // execute lengthy processing here; e.g. switch to a new screen with a lot of layout CursorManager.removeBusyCursor(); // remove busy cursor However, in practice, for certain situations, the busy cursor doesn't

问题 This discussion started over here but I thought it would be nice to have a definitive answer... So let's say you have MovieClip on the Stage (or a UIComponent for the Flex audience) - what do you have to do to not make it so that the user can't see the object but also so that the AVM2 doesn't even factor it in when rendering the stage for the user? I always thought the answer was to set visible = false but there is an argument out there that the object has to placed outside the boundaries of

问题 I'm trying to remove an eventlistener on (in this specific case) a HorizontalList. The list is initialized with the property itemRollOver="playPreview(event)" I'd like to remove this eventListener by switching state and stating something like: <mx:SetEventHandler target="{horList}" name="itemRollOver" handlerFunction="null" /> This doesn't seem to work. The event is still handled and playPreview(event:ListEvent) is still called. How to properly do this? (I know I can do it in Actionscript,

问题 I have prepared a very simple test case to demo my problem. Please just place the 2 files below into a Flash Builder 4.6 project and they will run instantly. My problem is that the menu attached to my (slightly modified) custom PopUpButton never changes - even though the underlying Array data provider is changed when you click one of the 3 buttons on the right side of it: AuxButtonTest.mxml: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s

问题 I have a strange problem where I am trying to build tabs in a tab navigator with a combination of mxml and AS-3. Somehow the last mxml tab contents are visible even on chosing the AS tabs- the problem is resolved afer the mxml tab-2 is viewed once e.g. when you have tab 2 as the chosen option and then click the button on top, the AS created tabs also show the mxml-tab contents- goes away after the tab is clicked through. Any ideas what's happened- and how to handle this? http://pastebin.com

问题 I am trying to use embedded fonts (Flex 4.6) in a UITextField. As long as I use a font that is registered with Windows, it works fine, but for a font not registered, the UITextField defaults to TimesRoman (or something similar) Note that when I check to see if the font is embedded, it returns True (FlexGlobals.topLevelApplication.systemManager.isFontFaceEmbedded(txtFormatCoda)) So what am I missing? In the code below, if I add the font Kredit to Windows Font, the UI text field appears in

问题 I have a single WAR that runs two servlets. One provides AMF remoting to Flex clients and other SOAP/HTTP to web service clients. I currently have Spring Security configured to authenticate the Flex clients using DaoAuthenticationProvider. However, I'd like to use a different authentication provide for the SOAP/HTTP. Possibly basic authentication or some other form. Is it possible? or do I need two WARs? 回答1: I think you'll run into problems issues with instantiating two security filter
