I have to allow user to print through my application. I am creating application for ios using flash builder 4.5.1
Here is the code for it:-
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<fx:Script>
<![CDATA[
import mx.printing.*;
// Create a PrintJob instance.
private function doPrint():void
{
// Create an instance of the FlexPrintJob class.
var printJob = new FlexPrintJob(); // calls the dialog
if(printJob.start()) // Starts when the user presses ok
{
printJob.addObject(dashPreview,FlexPrintJobScaleType.MATCH_WIDTH); // the object you want to add, and the scaling you want to apply
printJob.send(); // Send everything to the printers.
}
}
]]>
</fx:Script>
<s:Label id="dashPreview" x="334" y="110" text="naveed mansuri">
</s:Label>
<s:Button id="myButton" x="19" y="215" width="729" label="Print" click="doPrint();">
</s:Button>
</s:View>
But Whan I run this application and clicl on print, I got following error box of errors:-
Error: Error #2055: The print job could not be started. at Error$/throwError()
at flash.printing::PrintJob/start()
at mx.printing::FlexPrintJob/start()[E:\dev\4.5.1\frameworks\projects\framework\src\mx\printing\FlexPrintJob.as:200]
at views::PrintHomeView/doPrint()[C:\Documents and Settings\naveedmansuri\Adobe Flash Builder 4.5\Print\src\views\PrintHomeView.mxml:20]
at views::PrintHomeView/__myButton_click()[C:\Documents and Settings\naveedmansuri\Adobe Flash Builder 4.5\Print\src\views\PrintHomeView.mxml:34]
What wrong in this code? Is print class is not mobile optimized?
I have to print only a label text.
Sincere request to get me out of this issue. I have a release date soon for this application.
From the LiveDocs:
Mobile Browser Support: This class is not supported in mobile
browsers.
AIR profile support: This feature is supported on all desktop
operating systems, but it is not supported on mobile devices or AIR
for TV devices. You can test for support at run time using the
PrintJob.isSupported property. See AIR Profile Support for more
information regarding API support across multiple profiles.
Only way to print on mobile devices is through an AIR Native Extension.

I need to make flex mobile application to be full screen when it runs on desktop OSs (I've packaged it as an air app)
I'm pretty sure that your view will dispatch it's creationComplete event before the main Application is added to the stage, which is probably why you got the error.
In the past, I've used the applicationComplete event and the StageDisplayState.FULL_SCREEN. Here is an old blog post I wrote about it.
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" alwaysInFront="true"
applicationComplete="onApplicationComplete()">
<mx:Script><![CDATA[
public function onApplicationComplete():void{
this.stage.displayState = StageDisplayState.FULL_SCREEN;
}
]]></mx:Script>
</mx:WindowedApplication>
I see no reason why this code wouldn't work in a Flex 4 / Spark app.
Switching to full screen through stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE can not be done on a creation complete handler. It must be done through user interaction. I actually just did this yesterday. Add a button to your app and set the onClick to a function that sets full screen and hides the button. That's how I did it anyways.
I'm just getting started switching from flash to flex for the better components. I am trying the simple experiment of adding a button and then changing the label. This code does not work. It does not recognize myButton. In flash I could access a button instance after adding it using the instance name. Can't you do this in flex?
Thanks
<s:Button x="50" y="42" label="Button" id="myButton"/>
<fx:Script>
<![CDATA[
myButton.label="winning";
]]>
</fx:Script>
Flex have an Event based structure you can not just put command/expression in script block
it should be wrapped in function
like
private function changelabel():Void
{
myButton.label="winning";
}
and you need to call this function on an event like Click event of Button as
<s:Button x="50" y="42" label="Button" id="myButton" click="{changelabel()}"/>
You should read Migrating a Flash application to Flex
and to take a look in Flex you should vist Flex Developer Center
Hopes that helps
Trying to create a banner ad as a one-off project for a client. I am using Flash Builder / AS 3 and with my simple hello world example. Google Adwords rejects the add with: Encountered flash error - ad cannot use mouse tracking.
I Have not been able to figure out what I am doing that signals to Adwords that I am mouse tracking. Follows is my simple mxml file: (the handleClick is to adhear to their clickTAG specification)
Thanks!!!

It is quite possible that whatever automated analysis that Google does on the ads submitted is being confused by the Flex framework. You could try creating an ActionScript project instead of Flex project in Flash builder and see if that makes any difference.
If you use an ActionScript project you won't be able to use MXML for creating the ad, but you might not really even want to drag in the Flex framework, since it takes a while to load (the first time at least).
I'm a complete newbie to Flex, so apologies for my dumbness. I've searched for an answer but haven't found anything that seems to be doing the trick.
What I'm trying to do: port this example http://www.adobe.com/devnet/air/flex/articles/flex_air_codebase_print.html
to Flash Builder 4.
All seems to be fine but for one thing. When I use the original code for the Air application
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

creationComplete="onApplicationComplete()">
<fx:Script>
<![CDATA[
private static const neededForCompilation:AirGeneralImplementation = null;
private function onApplicationComplete():void
{
var can:MainCanvas = new MainCanvas();
this.addChild(can);
can.labelMessage = "Loaded in an AIR Application ";
}
]]>
</fx:Script>

I get this run time error
Error: addChild() is not available in
this class. Instead, use addElement()
or modify the skin, if you have one.
at
spark.components.supportClasses::SkinnableComponent/addChild()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\supportClasses\SkinnableComponent.as:1038]
If I substitute the code with
this.addElement(can);
Everything loads well but the first time I try to press any of the buttons on the main canvas I get the following run time error
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

<s:Button x="601" y="141" click="GeneralFactory.getGeneralInstance().airOnlyFunctionality();" label="Air Only"/>
</s:Application>
Any help would be immensely appreciated. And any pointers to how to setup a project that can compile in both Air and Flash while sharing the same code, all for Flex 4, would also be immensely appreciated.
thank you!
I ran into the same problem using that tutorial for Flex 4. I did the same thing as you and used the <s:Application> component for the Main Canvas. However the tutorial uses a <mx:VBox>, the solution I found was to change the Main Canvas from an <s:Application> to an <s:Group>. The problem seems to be embedding an Application within an Application.
The code on that link was written using the flex 3.5 sdk or below. You are using the new flex 4 sdk ( which is the default for Flash Builder ).
You can do the following:
1. step into the code do any necessary changes to make it work for flex 4 sdk.
2. setup a new project using the flex 3 sdk ( select "Use a specific SDK" and choose the Flex 3 from the dropdown box in the "New Project" window)
I would suggest going for the second option, make it work and once you've stepped a little deeper into flex 4 you can do the 1st option.
Cheers.
I want to embed a Flash movie into Flex (Flex Builder 3), both using Action Script 3, and have my flash movie call functions in Flex and vice versa.
Is this possible?
Yes it is possible. If you want to embed another swf into your flex application you have a few options.
Option 1 - Embed the swf, inline, into a SWFLoader component. This option has some security drawbacks as the swf gets loaded into another application domain and so communication between your flex app and the embedded content can sometimes be difficult. You can give this component an id, listen to the complete event and then talk to the content property of SWFLoader to get access to the loaded swf. Something like:
<mx:Script>
<![CDATA[
private function completeHandler(event : FlexEvent) : void
{
trace(mySwfLoader.content);
}
]]>
</mx:Script>
<mx:SWFLoader id="mySwfLoader" source="#Embed(source='YourSwf.swf') complete='completeHandler(event)" />
Option 2 - You could use a meta tag to embed the swf as a class and then create an instance of that class in code. This is gives a lot of flexibility but you loose the benefits of being able to add the object declaratively. Something like:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="creationCompleteHandler(event)">
<mx:Script>
<![CDATA[
[Embed(source="mySourceSwf.swf")]
private var mySourceSwfClass : Class
private function creationCompleteHandler(event : FlexEvent) : void
{
var mySourceSwf = new mySourceSwfClass();
myCanvas.addChild(mySourceSwf);
trace(mySourceSwf);
}
]]>
</mx:Script>
<mx:Canvas id="myCanvas" />
</mx:Application>
Option 3 - Don't have a swf at all. Have whatever you want to embed as a UIMovieClip in the fla. You can then create a .swc file whenever you publish that fla. You can then link to that swc file in flex builder. this will then automatically add that MovieClip as referencable in your project (this may need some more investigation on your part). Essentially you can then do something like:
<local:MyMovieClipInSwc id="myMovieClip" />
This way you get the benefits of both worlds, declarative markup and everything within the same application domain. One thing i would say about this method is that Adobe royally f**ked up with the UIMovieClip class and it's performance sucks. Just be aware if you start to use this everywhere you app may become extremely sluggish.
