Building Flex without MXML but with AS3 applications

It seems logical that if I want to build an application I should use AS3 to create reusable components, classes, the layout, etc.

.. However, looking around on the web exclusively finding Flex tutorials and examples using MXML. This also applies to the books (for example Adobe Flex 2 - training from the source) - why is - this?

Is it wrong of me to think that it would be better to create everything in AS3? Someone has links to tutorials etc where they use AS3 to create Flex applications?

I don't think that there is nothing wrong with assistance regarding your components - I do for most of my components if they are not containers available inside of them.

Using FlexBuilder gives you the ability to graphical layout, and that is something good and useful to use for layout components. If I extend a control and change his behavior I always use because it's a bit awkward to do in MXML, and there is no benefit to it. Sometimes, however, I am creating a component to be used, for example, as a popup - in this case, I create a mxml file that extends from TitleWindow and I can use the visual layout of the content editor.

In any application, you need to end up with something of Visual that involves the layout, so it is rarely likely to be an argument not to use MXML, at least for the Application. There is no runtime performance gain to use LIKE - even if I assume that the compiler saves a little time.

So in your example, I agree there is nothing wrong with this if the app:Test class is fully dynamic, but if you do a static layout inside the Test class you just cryptic for yourself and for any developer to keep this code in the future.

    Looks like you are trying to do too much at once. Try to hang the events correctly

    The close event of the comboBox can do something like this

    protected function toggleTextEditing(event:DropDownEvent):void

    {

    If (this.optionCmb.selectedItem.label is "Percentage")

    {

    This.Text1.editable = true;

    This.Text2.editable = true;

    }

    Else if (this.optionCmb.selectedItem.label == "Number")

    {

    This.Text1.editable = false;

    This.Text2.editable = false;

    }

    }

    The button's click event can do something like

    protected function save(event:MouseEvent):void

    {

    If (this.optionCmb.selectedItem.label is "Percentage")

    {

    If (this.text1.text == "" & this.text2.text == "")

    {

    Alert.Show ("text is empty");

    return;

    }

    on the other

    {

    }

    }

    Else if (this.optionCmb.selectedItem.label == "Number")

    {

    }

    }

    If you can put in your entire code, maybe I can have a look to see if I can find something wrong with that.

    You can open it by accessing it in the Applications folder? If so, you may have a corrupt Dock alias. Click and hold the alias and make it about 1 inch away from the docking station, then release. Then drag the application in the Applications folder in the Dock to create a new alias. When you have a new alias, control - click/Options/keep in Dock.

  • iOS error ITMS-90478 and ITMS-90062 downloading with the Application Loader

    Hello

    When you try to download the latest versions of my apps on iTunes with the application loader, I see these errors:

    Screen Shot 2015-07-28 at 10.16.55.png

    I unzipped the ipa and checked that the current version number is actually 14.10.0, so I do not know why this error pops up. I tried other numbers version as well without success. I see this error with different numbers for 3 of my 4 apps. These 3 applications are 32-bit architecture right now, I'm trying to upgrade to 64-bit with this build. The 4th app was 64-bit from the start and did not show this error, but I don't know if it is related to the error.

    I compile with the SDK of Air in Windows (18.0.0.180), if that makes a difference. Any ideas why this error keeps popping up?

    Thank you

    The behavior of the two numbers has been changed recently. Previously you could not increase the number of generation without increasing the version number, which, when using test flight of Appl'e system means that the beta has go through approval each time. If you can keep the version number the same, but increase the build number, the new beta does not have to go through approval.

    Watch 'Number of Build in the iOS of the AIR' in the release notes:

  • Product build ANT not work package with AIR SDK 3.5

    I used AIR SDK 3.1 and ANT script to compile and package the application iPad (AdHoc to test). I tried to go to 3.5 SDK today but when I install *.ipa and launch on the iPad it hangs on the spalsh screen.

    You can try using the settings used by Flash Builder to package the application, details that are:http://helpx.adobe.com/x-productkb/multi/compilation-results-flex-builder-flex.html

    Update your ANT script with these and try again.

    Please come back and tell if it solved the problem and what changes had made you your ANT script.

  • Possible to pack the Air runtime with mobile application?

    Many friends told me that if my mobile needs something else to be installed to run application, they will stop. According to me, unless the majority of installed mobile Air runtime in the future. We need to make the installation easier to use.

    Can I bring the runtime with app? Or is there another autour work?

    Flex 4.6 / 3.0 introduced captive Runtime, Air which is exactly what you're asking.  You choose the version of Flex/Air to include in your application and it comes in the build.  This was the only option for iOS, but is also now available for Android.  When you export a Release version of your project in the latest version of Flash Builder, there is an option tab deployment "export application with the runtime in captivity".

  • How to create and modify an itemRenderer with AS3

    Hallo. In fact, I have this code:

    "" " < s:List id ="myList"width ="92%"height ="85%"left ="44"top ="80"skinClass ="skins.mioList_skin">

    < s:layout >

    "< s:VerticalLayout gap ="5"""/ >

    < / s:layout >

    < s:itemRenderer >

    < fx:Component >

    < ns2:myItemRenderer / >

    < / fx:Component >

    < / s:itemRenderer >

    < / s:List >

    This code works perfectly. This is the mxml code. I want to create exactly the same structure but with cause of as3 code, I need to change (because the component is created) the itemRenderer. Specifically, I have a variable named listType which can take 3 different values and for each value, I have a different itemRenderer. How can I do this with or without as3?

    Thx for all

    Max

    All properties need to be configured at the same time:

    mioItemRenderer.properties = {myVar1: 'myText1', myVar2: "myText2"};

    I don't think you can change that setting via AppleScript, however once you have enabled then the XML file will be generated and updated every time that the library is updated.

  • Why I get so much ball of color with some applications

    Hi, I got an iMac old mid 2010 27 "with a processor i7 and 8 GB of memory. I got a lot and long color ball (beach ball) with many applications.

    I bought a new iMac 21 "(fin novembre) with the highest CPU available i7, 16 GB of memory and 256 storage Solid State." So, I thought: bye bye to the beach ball, but this is not the case. If I saw only, Safari and Adobe Muse (in sleep mode and I start Contact (my contact book), for example and I'm going to edit mode to edit a contact, it takes a few seconds with the ball of color to enter edit mode, if I change anything in a contact, then the colored ball is there for about 6 or 7 seconds.) If I make a change without Muse in standby mode, it is almost instantly change anything in contact and get out.

    Is this normal? Even when the Muse or large applications are in mode sleep or just simply presents? Even if I do not use Muse while I do something else? They have a lot of memory and the processor is "bored" because there is nothing happens. :-) Is there a system setting that I should change? Thank you.

    There is probably something in your user account that is the cause. It is NOT normal.

    There are a few simple things that you can try:

    1) starts in Mode safe. Then start normally. Note: your mac is supposed to be slower in Mode without failure, but in your case, it might actually be faster.

    After you restart normally, you will find that your mac is now ok. If so, this means that a corrupt cache caused trouble and now everything is fine.

    Otherwise:

    (2) create a new user account and use this account for a while. You can see that there is no beach balls. If so, the problem is specific to your user account.

    (3) download Etrecheck, run it from your normal user account and post the report here.
