ActionScript 3.0 :: Preloader For A DB Driven Flex Application?
Aug 23, 2010
I have one application where GUI and Data are rendered from database. So the application takes atleast 20-30 seconds to load on a browser as hugh data come from database.Now I added preloader for this application but I face a problem with this preloader.The preloader is hangs in between and again it ends before my application get load propertly.So will you please suggest me the proper way to use the preloader so it won't stop or hand during initialization process.
We are trying to automate our flex application. After adding automation libraries to our project we get the following exception:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at mx.automation::AutomationManager$/addDelegates() at mx.automation::AutomationManager$/addDelegates() at mx.automation::AutomationManager$/addDelegates()
[code].....
We are using Flex 3.4 and maven2 to build the application.
I have this nifty little 3D Carousel url... which I learned to build at url...I would like to know if it is possible to add a preloader.One that is visible while the xml images are loading...or one that hides the xml images until they are all loaded...either one is fine with me...any ideas?
I have following AS code for XML driven PhotoSlider which needs a PreLoader because the first image loads too slow. how to implement into this XML Flash sldier?
I'm working on a little project in Flex that's an application to upload images to a server. Since it's a pretty lightweight application (~40 kb in release version), I would like it to display instantly when the html page is loaded. But somehow there's a delay of up to 1-2 seconds before it shows up. I think it is a delay actually between the load and the display of the application, and I believe it could be removed.
how to shorten/remove the delay. First, I tried to disable the preloader, but this did nothing. There's actually a delay between a preloader shuts and the application displays (it is around 500 ms - 1 sec). My next guess was to write a custom preloader class to display at least an image of the application (even though it wouldn't be clickable, but at least something).
I want to call a function in main flex app from the custom preloader code in actionscript before it dispatches complete event. Also i want to know how to call back to a function in preloader code from application
I bought a flash site template that loads xml driven swfs inside the main swf as different menu items are clicked. The modules that come with the template work fine, but I don't know how to add a third party xml driven swf, so that it shows up properly. While the third party swf works fine as a standalone, the embedded version loads just an empty movie.
I am working on a page which mainly consists of Charts and Grids. Thought that Flex would be the best fit with some cool effects. But however, I now feel that ExtJs grid looks better than Flex data grid.
My question is whether there is any possibility / mechanism to embed Ext JS grid into a Flex page. Lets say my main page has a Flex tab panel. In first tab, I would like to see 'Flex Chart' and in second tab I would want to see 'ExtJS grid'.
I would also want to know of any Flex Data grid plugin (if exists), which looks/works just like Ext Js grid.
using model driven development in developing enterprise applications. Adobe's LiveCycle Data Services looks very promising, I have found numerous tutorials/videos that shows how fast an application can be build by having methods/functions auto-generated.What are the best-practices, is it good/bad to use those auto-generated methods, they can really save a lot of time.

I've made a component based on a mx:TitleWindow that contains linkbuttons that I'm using as a context-menu. The TitleWindow component contains link buttons like this:
[Bindable] private var _showEmailThis:Boolean = false; [Bindable] private var _showApproveThis:Boolean = false; [Bindable] private var _showReviewThis:Boolean = false [Code] .....
This component contains a large number of links and is re-used by multiple modules in the same application. Within each module, this component is used when a user clicks on a row in a datagrid. The code looks like this:
In "Requests" module: private function dgRequests_click(event:MouseEvent):void { menu.showApproveThis = true; menu.showReviewThis = true; }
In "Performance" module: private function dgPerformance_click(event:MouseEvent):void { menu.showEmailThis = true; menu.showReviewThis = true; }
As you can see, the visibility of individual linkbuttons is controlled within each module by setting boolean properties. If I alter this component to use a renderer, how can I control the visibility of the linkbuttons from the code in each module (there are over a hundred links with different functionality - not every link will be used in each module)? Note: it is not known from the back-end which grid within which module uses which link. This is set in the front end within each module's actionscript file. E.g., if the XML looks like this: [Code] .....
And I set the Email link to show in the module like this: private function dgPerformance_click(event:MouseEvent):void { menu.showEmailThis = true; }
How do I make it take effect? Is there a way to control the visibility of a linkbutton within an item renderer in a component from the module that uses that component?
I'm trying to develop a simple mxml Flex application to start Skype from the AIR/Flashplayer runtime. Is it possible to get back events from a native Windows application? In the simple example of Skype, the OS returns control to the Flex app when Skype exits. But what about native applications which have their own event model and wants to communicate with the Flex event model. For example, a Face detection system which shows "Hello" on a Flex app when the camera detects a face. Can this be done in the current Flex framework?
I am working on an Adobe AIR Application. The size on Application window is 800X600 and is contains border container and border container contains many controls. What I want is to if user re-sizes the application then that container should also be re-sized according to scale. i.e If user maximizes or minimizes the window then that border container should also be maximized or minimized respectively.
how can i delete storage directory instances or folder while uninstalling any air application. In my application when i first time run my application, application copy some data from application directory to application storage directory. now i want to delete all data and application directory folder also while uninstalling application.
I am doing that because when i launch any update then application is accessing old data which conflict with my application new features.
I'm new to flex. Now I'm writing an flex application. I plan to split my application into some MXML files(Application as the root tag). How can I switch from one mxml to another?BTW, what is the best practice for design large flex application? Just one MXML Application and many MXML component or many MXML Application?
I want to read xml data to a mxml application from a xml file on my filesystem. The example I found was for AIR,link2, link3. But I want to target the Flash Player runtime. If I use the the tag, I can do it; however the xml compiles into my swf. How can I retain the xml file in my release build?
i used systemManager.addEventListener in sub application...... it is working well....but when i load sub application into main application through swfloader it doesnot working..
I have a native (Obj-C, standard Xcode project) application and I'd like to integrate a partners iOS application (or specifically, it's functionality) into it as just another view in my application. The problem is that their application is a Flex/Air app. I really don't understand the Adobe compilation process on how it gets from a bunch of flex code down to an IPA. I don't see intermediate projects, shared objects, etc on the disk to produce that IPA. It looks like it doesn't rely on the Apple tool chain... as I understand it, you can produce the IPA on Windows as well. Is there any way to build that Flex app in such a way that I can import it into Xcode so I can link against it and use it as a library from within my application? While I specifically used iOS as an example since that is the most important platform, we'll want to apply this solution to our respective Android and Blackberry 6 apps as well.
I have an AIR application with a system tray icon. When clicked it shows and activates the app. This is working as expected when the app is hidden (docked), however if I select another application so my app is in the background clicking on the system tray icon does nothing.
Oddly I also have a contextual menu on the system tray icon, which has an option to restore, this calls the same event handler as ScreenMouseEvent.CLICK, yet works.
I expect it's something to do with the contextual menu changing the focus, perhaps it's a bug in how AIR works with the system tray, perhaps it's just something I'm missing. Would be good to know if that's the case.
I've been trying to launch a separate Air Application through my current Air Application.Both apps are compiled using the Adobe Air 2.0 SDK. The methods I have found so far involve passing the Publisher ID in addition to the Application ID, but I believe the Publisher ID became redundant past Air 1.5.3? Below is my current implementation whic seems to correctly ascertain the Air Application's version number, but when I try to launch it, nothing seems to happen.
private static var _air:Object; private static var _loader:Loader; private static var appID:String = "someOtherAirApplication";[code].....
I have changed the app-config.xml (app descriptor) on the application I am trying to load to allow browser invocation.The version number of the app descriptor of my application I am trying to load is "V1" which the versionDetectCallback seems to pickup. If this is the case I would expect to be able to launch it but this doesn't seem the case.
I want to load a flex application in mobile flex application and also i want it to interact with the parent application. Right now I am trying to load the swf with swfLoader in mobile app, but it gives me security error. And also should I want the parent application to be generic in terms of child application as in down the line if someone wants he can have another child application with same name run.
I've created a client with login acces in Flex. After the succesful login i have to show a table based on a mySQL server. The database is composed by some tables, and I have created 6 flex mxml components with each own scripts for each of those tables. How can i load sub-applications, for example with a PopUpButton or a TabBar in the main application?
I have a program consisting of multiple SWF's. An AS2-SWF loads a bunch of AS1-SWFs.It's a crappy program.I'd like to specify the GUI in MXML and perhaps refactor some code to AS3. However, converting all of the 300+ symbols to AS3 or whatever is undoable.What are my options in converting to AS3/Flex/MXML? The app is very simple, only also quite large. It consists only of buttons, backgrounds and attention-texts. All the button texts are in XML files.I want to turn this into pretty code ASAP but also controlled so the code becomes:[code]Of course doing this is on my own initiative, if it'll take more than a week, I won't be able to find the time.
Below is the overriden on complete function for a preloader in Flex.
private function initComplete(e:Event):void { //dispatchEvent(new Event(Event.COMPLETE)); cp.status.text="Configuring... Please Wait"; }
What I want to do is when the app has finsihed loading I want to change the preloaders text to "configuring".Then I want to go and do a bunch of setup stuff in my code.Once I've done all the setup I wanted how can I get the Preloader to dispatch its Event.complete from else where in my code?I tried Application.application.preloader but it comes up null.So I guess my question really is how to access a preloader from anywhere in my application. Would a better approach be to have all setup classes as members of my preloader class?
I have a AS spinner class that I downloaded from Jake Hawkes (click here to see it running).I want to replace the flex application preloader with this spinner. I have previously used custom preloaders, but that was just for editing what already existed. Anyone know how that spinner.as could be used instead of the loading bar?
EDIT: This is the extremely cool custom preloader that Im going to try to edit (it extends Sprite) view source enabled:[url]...
I have two flex applications Main.mxml(where I have a button called loadDataViewer) and ViewData.mxml. What I want is when the user press the loadDataViewer button, the application ViewData.mxml will open in a new window. Is there any way to do it in Flex?
SWFLoader class looks interesting but I think it will load the other appliation inside the Main application which I don't want.I also saw that there is ExternalInterfaceAPI which can be used to open a url browser but not sure if I can reference the swf file of VewData application.As suggested here( http:url... ) that LocalCOnnection can be used to reference one flex application in another but that's only when both applications are open I guess?
