import the classes in Flex applications

I am a writer experienced AS 2.0, but I'm new to Flex. In fact, I'm taking the training AS 3.0 by Lynda.com with Joey Lott, a great teacher in my opinion. However, the thing that I find most confusing is when to import a class and what to import. With 2.0, most of the classes is to extend the MovieClip class, which is imported automatically all Flash files. Now, it seems that I have to import a new class just to accomplish the simplest, as tasks by clicking a button, create a button or even go to a URL. I find it very frustrating that I cannot infer that classes to import, I have to wait for a mistake that is not intuitively written itself, let alone WHEN to import anything. Is there a bibliography or tutorial that would help me get a grip on this apparently declined characteristic of the evolution of the language? Better yet, since I have yet to see Flash 9, Flash 9 continue to do a lot of his own class import, and in the meantime I just treat the hard knocks of Flex? A big thank you to anyone who was in that boat and can lend me some encouragement.

You need to import a lot more classes in ActionScript 3. This is because the language has become more mature and have complete definitions allows the compiler to work faster and generate better and more efficient code.

If you are using Flex Builder 2, you will get help. For example, suppose you want to create a DataGridColumn in ActionScript, but you don't know what class to import. If you start typing "var col:" when you hit the colon, FB displays a list of possible data types. If you scroll through this list (or start typing DataGridColumn) and select DataGridColumn, FB will add import for you:

Import mx.controls.dataGridClasses.DataGridColumn;

You can also use an import of generic drugs as flash.events. * where the * wants to include all of the classes in this package. But don't worry, the compiler put in the SWF file actually used classes. I find it better to be explicit about the classes because it tells the reader exactly what foreign classes are used and they came.

I use this feature of Flex Builder all the time; I can't remember where all the live classes.

Hope that gives you more confidence.

  • Import the image in FLEX

    I'm testing Horizon FLEX, but I have problems to import an image. I followed the steps of creating a virtual machine with VMware Fusion Pro. Encrypted virtual machine, restrictions, type of restriction enabled = managed and registered Management Server (mirage).

    When I select the vmx file to download, I get the message that this is an invalid image. What can I do it wrong?

    This fix worked for me:

    -Open the .vmx in a text editor.

    -Implement "displayname" "displayName."

    -Save the .vmx

    -import the .vmx in FLEX administration console.

    It is in the release notes:

    • The Horizon FLEX server cannot handle the full virtual machine name defined in the .vmx for a virtual machine if the displayName property is not what she expected.
      Solution: Edit the .vmx for the virtual machine so that the N displayName is uppercase and all other letters are lower case.

  • Shortcut for the associated debug flex application

    Right now I'm working on an Actionscript * library * and I have a separate flex application that I use to test the library.  When I'm coding in ActionScript library and I want debugging, I have to move my mouse to the little Ladybird on my toolbar, click the arrow at the bottom, then select my flex app test.  ARG!  I'm too lazy.  It is possible to connect a shortcut (like F11) to run the flex app test?  When I hit F11 when I am coding in the library of SA that it does not do anything because he's not smart enough to know I want to launch the Flex app rather than the library of SA. Thank you.

  • The multi-version Flex applications | is this possible?

    I have a Flex Application that contains 2 modules. The Flex application is compiled using Flex 3.0 SDK. My question is: I want to compile only those 2 flex modules using Flex SDK 3.5. In this case, if modules can communicate with the main application without any problem and how to implement it? Please explain in detail.

    Mixture of versions with their charger and modules is not supported.  There are

    messages on the support of cross-management of versions of "Marshall Plan" that uses

    under apps instead of the modules in the doc of flex and my blog.

    However, mixture of version not be prevented.  If he happens to work for

    because none of the classes and common APIs introduce incompatibilities,

    then you can go into production with such a configuration.  Generally

    check for errors and are easy to find, but no cause of incompatibilities

    always...

  • Could not import the class with CFCS

    I created a swc file.  I can import most of her classes in my project, no problem.  A single class, however, simply will not import.  I tried to copy the swc directly in the project, citing computer source folder, etc.  No dice.  The EFA relies very well so there is no error in the class.  The first lines of the class like this:

    package com.thismoment
    {
    import flash.events.Event;
    SerializableAttribute public class TakeEvent extends Event {}

    I should be able to import com.thismoment.TakeEvent; right?  It does not work.  I get "1046: Type was not found or is not a compilation constant: TakeEvent.»

    How can I find what is happening?  Is there a way to clear all the classes in a swc?

    Sorry if it's repetitive, but you confirmed that the class is visible outside the CFC? In the project "thismoment" go to your Flex Library Build Path settings and make sure that "include all the...» "is selected or that"TakeEvent"is selected in the tree.

    See attached screenshot.

  • How can I import the filing of an application to another application...

    I see no option to import a repository from another application into the current application.

    Is it possible to do...

    If you want to copy assets from one server to another, the best way is to create an ACL on the original server and import it on the second server.

    If you want to copy assets from one application to another on the same server, then right-click on the assets and select copy.  Right-click on the target application and select Paste

    any help?

    you will need to use the path to your file (s).  you will save you a lot of time by moving this file to the same folder or a subfolder of your current application.

  • import the class causes freeze

    Here is the code on _root SWFs:

    Application.Main (Thi, "Menu");

    even with the second row to comment, we get a great gel, seconds entire queue. the film just completely stops playing, even an onEnterFrame on the _root method does not work until the import is complete. just nothing but waiting for the import code. Application.As links out of a MVC architecture with a whole bunch of extra categories, etc and the inclusion of this line is enough to transform a 3 K swf in a 443 K swf file.

    Hello

    http://gumbo.flashhub.NET/keyboard/

    It is a small example of a 'virtual' keyboard that will enter the text into a textinput/textarea component selected. Capslock and shift key States really aren't quite right (really need control shift/cap lock combo), but there is a simple tab and backspace (delete) and enter the function key.

    hope this is useful

    David.
