Actionscript 3 :: Flex 4.6 Mobile - ItemRenderers And Application Data?
Mar 20, 2012
A question about ItemRenderers: let's say I have an ArrayCollection that is my application data sitting inside a global object. I them populate a sparks list with this data, setting the ArrayCollection as the dataProvider.
So each ItemRenderer gets a copy of an item sitting in the array. You can override the "set data" method to set the data something more domain-specific. The problem is that the data is a copy of the original item.
Now let's say we want to add some data to the item while inside the ItemRender. For example, it could call a method on the item telling it to load some details about itself, or maybe we allow the user to modify something on the item.
Obviously, we can't do any of this if we are operating on a copy because it will be thrown away as soon as the ItemRenderer is destroyed and the original object doesn't know anything about what happened.
So what's the best practice? Should I just use the itemIndex of the renderer to pull out the original item from my global array like this:
{globalArrayCollection}.getItemAt(this.itemIndex) But it seems kind of clunky to me. Is there a best practice for dealing with this?
I'm developing a mobile AIR application using IntelliJ.
When debugging in Flash Builder there is an option to clear to application data on each (debug) launch of the ADL (see screenshot below) However, I can't find this setting in IntelliJ or some ADL parameter to force a clear on each new debug session. I was wondering if such an option exist in IntelliJ or ADL.
A little background: I'm using the PersistanceManager in the application to store some user settings and I want to be able to start the application without the saved settings from my previous run. Using this setting in Flash Builder does the trick, but I'm having no luck with IntelliJ.
I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
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 have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based? I am hoping that there is a plugin somewhere or maybe html5 has some magic in there that supports it.
I'm making a mobile application with abobe air and flex.I want to know if it's possible to do it without ViewNavigator, or at least for some part, use something else.
I'm quite new to developing in Flex. I've found out that it's possible to create mobile applications with Flex 4.5. So far so good, I've made an app and it's working well on my mobile phone. But there is one thing that I'm not very happy with. When I'm installing the app I also have to install Adobe Air (stand alone application). So is not realy cool and not the way to go in my opinion because this will look strange to the users of the app. And especially the users which aren't realy 'geek minded'.
Any solutions to this? Is it possible to include or embed Air in the app? It will make the filesize of the app bigger but that's a much smaller problem then having to install a complete different app next to the real app.All the best from NL.
the thing I mean cannot be probably done with the component, but I don't know how is the component I want called. I would like to achieve a list but with sort of "icon look". You could say some sort of springboard navigation.
Here is just a quick sketch in Photoshop how it should look like: [URL]
The item is the one actual item in the list or something.
Is updating a Flex Mobile Application done in the same way an Air application is updated? Can't seem to find information specifically for mobile on this. Apparently, if I trace out Updater.isSupported, it gives back false. From the Adobe documentation: The AIR update framework is only supported in the desktop profile. It is not supported for extended desktop applications (applications installed with a native installer), and it is not supported on the mobile profile (iPhone applications written with ActionScript 3.0). Check the Updater.isSupported property at runtime to see if the update framework is supported. So how do you implement updates for Mobile Apps created with Flex (Android + iOs)?
I am going to write a Flex mobile application which can benefit from loadable modules, but encountered "Modules are not supported for AIR mobile applications." statement here.
Is there any workaround to load swf modules (containing UI with some code) in the mobile application developed for iPhone/Android/BlackBerry?
I made a simple Flex mobile application to test TextInput fields. I define my View with width=height=100% and use vertical layout. Inside I'm simply placing static TextInput components with width of 100, 200, 300, 400 respectively.I'm also displaying the width of each TextInput in its text property and it shows values which I've defined. What bothers me is the actual width of the TextFields doesn't match the properties of the phone emulator I'm running (Samsung Epic WxH = 480x775) or actual device. For instance the TextInput with width of 400 completely extends past the left and right sides of the device, while it should be contained inside it: it's 400 pixels wide and device has 480 usable pixels available. So do all other TextInputs.
I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.
i have a mobile application that i am attempting to use to load an interactive .swf file. At first, i was just going to use the .mxml applications from my other project file in flex, but they're for desktop apps and running on Flex 3.6, and Mobile apps can't be built on less than 4.5 :P
so, i figured i'd export the first project to a .swf, and load it in my mobile application, but nothing i do will get it to show up. anyone know a solution?
I have a mobile application that uses an sqlite database. I cannot seem to figure out how to access the next record when the user presses the 'next' button. My database is using 'id' as primary key with autoincrement as integer.
private function nextMoveRPart(event:EffectEvent):void { var cardNumber:int = parseInt(cardNumberLabel.text);
The current mobile application I am developing in Flex calls for a client to be able to electronic sign a signature box in a document with their finger (This is a tablet application). Does anyone know of a good way to accomplish this in a Flex Mobile Application?
I have a flex app using the 4.5.1 sdk and AIR 2.7 running on an Android 3.2 tablet. During use, I can get it to crash fairly regularly. It's usually when I'm rapidly scrolling around in a List control. I can't seem to find the cause.
The application will just suddenly close. It happens in both debug and release builds.
When in debug mode, it just disconnects from the debugger and doesn't give me any useful information.
I'm at a loss on how to debug this. What are some techniques I can use?
I found the "adb logcat" command. Relevant info from the log below, unfortunately it doesn't mean much to me.
What is the best way to display a large amount of text (5000-10000 words) in a Flex mobile app?
I have been loading text in through an xml file using itemrenderer. It works totally fine when I run the application on my PC but when I load it onto my Android phone it crashes. Looks like my phone can only handle loading in about 3000 words using this method without crashing.
Anyone have a suggestion? Also, HTML isn't going to work for me. I want the text built into the application, which is why I have been trying to use the xml file.
Currently i am working in mobile application development in flex4.5 . i want to know whether there is any possibility to make the auto update feature(regarding the verison) in mobile application using flex 4.5 .
i have a mobile application that i am creating in Adobe Flex (Flash Builder 4), and i am trying to create a zoom function. The one i have works, but the point is to be able to more easily read words that are in the image (the images are .jpg files). The images are 2550x3300 originally, but as soon as you zoom, the image quality reduces drastically, and nothing is readable.
I read that using Flash Builder 4.5.1 you can create one application and run it on a mobile device, in Internet browser and in Desktop AIR. However, I created a mobile application and the only option to run it is 'Run as mobile application'. Is it really possible to run the same Flex application in browser and on mobile?
I am trying to get some code working from an example I came across. most of the functionality works but it is failing when it tries to dispatch a custom event. At the moment the code that is trying to dispatch the event is inside a class that handles amf remoting.the example has this line in it for the dispatch:
I would like to learn Adobe Flex mobile development.I have created a new project called SampleProject, then I got SampleProject.mxml in default package and SampleProjectHomeView.mxml.[code]How can I call the add and sub methods from the class above in SampleProjectHomeView.mxml?
I am working on a try-out app targeting ios and adroid mobile devices and I use flex 4.6. I want to hide the app in the list of running applications. Is it possible?
If not, is there a way to change the name and icon of the app in run-time after installation?
Is there any way to embed YouTube video/video player into Android Flex AIR Mobile application?
I tried to use SWFLoader(...) but since its MX library class only works on the desktop runtime environment, but fails to work on actual Android device when debugging the application.
Maybe it's possible to embed HTML that contain YouTube video into some Flex media container like TextArea or something?
I am trying to implement Stock Charts in my Mobile application created in flex.what i need to implement is the cross hair as seen in [URL] how this can be achieved.
I have a spark datagrid on a mobile application, I set the
interactionMode="touch"
and the dataGrid scrolling is good, I got some problems adding a selectionChange eventListener to it, because scrolling the dataGrid will automatically change the selection and instead simply scrolling it, the function binded will start...
How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?
