• Public static var - quick question

  Gidday

  Slowly converting my calendar code AIR dekstop app to OOP, and I'm at the part where I am loading in the user settings in a SQL table.

  I was wondering, is a public static var one good thing to use for holding user settings?

  I thought I had a class UserSettings user settings that may be held to get and set as they are needed or changed.

  Click Save, I can just walk them and save them in SQL.

  And all my classes can access them if necessary.

  Or is there a better way?

  See you soon

  Be more specific on what is YipeeClass and what he really needs. YippeeClass probably doesn't have access to all settings variables.

  For example, if YippeeClass is a point of view, he's probably just things it is designed to show. Provide you (getters/setters) properties on the view and then your main class for the Document (or better yet, a controller class dedicated) looked at the settings and fill in the properties of the display according to relevant parameters. Don't worry the Document class on how these parameters affect the view - it will be now responsible for displaying to translate the properties in any way (for example, to set the text of a text field). This is known as Dependency Injection.

  If the user interacts with the view in a way that impact parameters, send you an event to the view which is intercepted by a controller or the main document class and that class then will bring the necessary changes to the settings.

  Classes should always know the strict minimum necessary to accomplish all that they are directly responsible, and each class should be responsible for something.  I suggest you get the book associated with the links I posted: Actionscript 3 Design Patterns. At least she would give you a framework to think about such things.

• PhoneListener cannot access a public static vars initialized in the main thread

  Using the emulator (SDK 4.7, phone model 9500)

  I have a class PhoneListener defined and recorded, he gets the phone events without any problems. It's all public static public var that is initialized in the main thread is always null when it is examined in the context of the PhoneListener callback thread, when examined in the main thread or a son they are defined.

  I guess since the PhoneListener callbacks are called from a system thread, it cannot access the battery of my request - it seems correct? is this in any way about this?

  I tried Application.getApplication () .invokeLater (...), but validated all executable from the PhoneListener recalled suffers from the same problem.

  Thanks - Lindsay

  Exactly, that's what I was wondering - I found the answer according to the PhoneListener in the MIDlet . Now I store my UiApplication object in the running store and access them from the PhoneLister to publish objects on my main application via invokeLater.

  Thank you

• How to reference a global non-statique Timer var from a static context

  Hello. I need to have a single world clock for my application, which can be canceled and re-scheduled for a different date, to within a few static methods in the application.

  I confess that I do not understand how the static. I'm now declaring my Timer as static at the class level (so it could be accessed from static methods), but it does not seem to keeps its value and is null when it should have a value. To be exact, I set my Timer = new Timer() variable of in a method static and annex, then return to cancel it and reschedule, only to find the timer variable is null.

  What I want is to have a single global Timer, so some code runs when it gets to zero (I don't want to declare a local var Timer in my calendar and static methods because then I would have several timers). And I want to cancel the account countdown and the reporter at will. (There is an another Timer for another purpose, but I want just a thin Reset).

  I noticed that my level variable class static Timer (I thought that a timer could not be static) could be assigned to = new Timer() - it compiled correctly. My limited understanding is that static variables contain no instance, so I'm struggling with this. Reading, I think that in a static context, you cannot reference non static var because Java does not know which instance of the object you want.

  I found that if you want to access a non static var from a static context, you must first instantiate the class container and say classname.globalvar in the static context. Problem is when I tried that I found that I already had an instance of the application running, as I instantiated my UIApp in main() just before I entereventdispatcher - so an exception has been thrown. My application was created using JDE 4.6 and it's a UIApplication.

  How do you have a class-level Timer, referenced from a few static methods, cancelled and postponed? Or I go about it the wrong way? Never appreciated as ideas.

  Justin.

  @icefrost1.  We could discuss on this point, but since the Original Post, I think that the simplest solution is to use a Singleton.

  But in fact, we must be clear on what is actually the Singleton.  In this case, I have this code so that the Singleton contains a reference to a timer, i.e., it is not the timer itself.  The process may update the reference to the timer, so that any other treatment sees the update timer.  At least that's how I'd do.

• Static Classes & events

  Can it only an instance of a class expedition event, or the static class can too?

  We have static class MyManager:

  package managers

  {

  Import mx.rpc.CallResponder;

  import of services. MyDataService;

  Import valueObjects.MyValueObject;

  Public NotInheritable class MyManager

  {

  public static var updateDataResult:CallResponder = new CallResponder();

  private static var myDataService:MyDataService = new MyDataService ();

  private static var myValueObject:MyValueObject = new MyValueObject();

  Public Shared function updateMyDataService (): void {}

  updateDataResult.token = myDataService.update (myValueObject);

  }

  }

  }

  And the other class which calls:

  import managers. MyManager;

  MyManager.updateMyDataService ();

  MyManager.updateDataResult.addEventListener (ResultEvent.RESULT, resultReceived);

  and this event listener does not work.

  Hi Banditizm,

  Yes you can even send your static callResponders events, but I think that the difficulty you might face you cannot capture or listen to events sent.

  You can do something, you can send these events w.r.t. systemManager and also listen to these WRT events there.

  I mean your shipment to help call the event as below...

  systemManager.dispatchEvent (new Event ("dataLoadComplete"));

  And you can listen in your mxml or as .as file below...

  systemManager.addEventListener ("dataLoadComplete", onDataLoadComplete);

  Thank you

• Avoiding the need to compile static content...

  Hello

  Without in any way, to download fonts on the fly for mobile content, especially of iOS, I have compiled about 70 MB of fonts in the app. This, of course, takes A Long Time. And whenever I change whatever it is, it seems to be done _again_.

  But do not change the fonts...

  Can anyone suggest a way to always include the established policies, integrated media, but without having to recompile the every time? For example, if I as compiled SWF CSS to them, can I integrate those who in a way that will avoid the need to link to the top of my task of "building workspace"?

  Thank you
  G

  Yes, it did.

  1. create a library project with a single component set that includes a with my mammoth font style sheet
  2 when the workspace of construction is complete, add the .swc to the /libs folder of the dev projects
  3 remove references to fonts in dev projects
  4. put a public static var on my class from the main application to the class containing all my fonts
  5 does.

• error of static class

  I have a static class:

  package VO
  {
  public class ArrayValues
  {
  private static var instance: ArrayValues = new ArrayValues();
  
  nominal values will replace the first with English-language versions
  If the user clicks on "Spanish" they will be replaced with
  private var yesNoArray:Array = new Array('1','2');
  private var utilityArray:Array = new Array('1','2');
  
  public void ArrayValues()
  {
  error ("ArrayValues is called by its instance");
  }
  
  Public Shared function getInstance (): ArrayValues
  {
  return instance;
  }
  
  public function getYesNoArray (): Array
  {
  Return yesNoArray;
  }
  public void setYesNoArray(input:Array):void
  {
  yesNoArray = entry;
  }
  

  It is invoked here:

  import VOS. ArrayValues;
  import VOS. InputData;
  import VOS. InputLabels;
  
  [Bindable]
  public var saveData:InputData = InputData.getInstance ();
  
  [Bindable]
  168 public var getArrays:ArrayValues = ArrayValues.getInstance ();
  ...

  It generates this error:

  Error: ArrayValues is called by its instance
  to VO::ArrayValues() [C:\FSCalc\Flex\FSCalc\src\VO\ArrayValues.as:14]
  to VO: ArrayValues$ cinit)
  Global $init () [C:\FSCalc\Flex\FSCalc\src\VO\ArrayValues.as:3]

  in FSCalc / _FSCalc_InputForm1_i)
  in FSCalc / _FSCalc_Array6_c)
  ...

  What I am doing wrong?

  PS, it is normal to take almost 10 minutes a) go to your discussions, b) read a reply to a thread and c) come back to the normal discussion?  That seems excessive to me.

  If you try to reach singleton,

  Your manufacture should look like this,

  public void ArrayValues(access:SingletonEnforcer)
  {

  If (access is nothing)
  {
  error ("ArrayValues is called by its instance");
  }

  }

  a variable,

  public static private var _instance: ArrayValues;

  Public Shared function getInstance (): ArrayValues

  {
  If (_instance is nothing)
  {
  _instance = new ArrayValues (new SingletonEnforcer());
  }
  return _instance;

  }

  And another class in the same file,

  class SingletonEnforcer
  {
  }

• Singleton and static class

  I found that some guy coded their static classes in their Flash programs such as this:

  package {}

  class SingletonEnforcer)

  }

  package {}

  SerializableAttribute public class StaticClass extends EventDispatcher {}

  private static var _staticClass:StaticClass;

  public void StaticClass (singletonEnforcer:SingletonEnforcer) {}

  nothing

  }

  Public Shared function getInstance (): {StaticClass}

  if(_staticClass == null)

  {

  _staticClass = new StaticClass (new SingletonEnforcer());

  }

  return _staticClass

  }

  }

  }

  And these days, I read some Flex project code as:

  package {}

  public class StaticClass {}

  protected public static var _instance:StaticClass;

  public void StaticClass () {}

  public static class

  }

  public static void get () of the instance: {StaticClass}

  If (_instance == null)

  {

  _instance = new StaticClass ();

  }

  return _instance

  }

  }

  }

  What is the difference between the two approaches? Why the SingletonEnforcer class is needed in the first case?
  Thanks in advance!

  singletonEnforcer is not necessary in the first example, and they could use one in the second example, if they wanted. With the help of the enforcer allows to raise an error in the constructor and say an error such as: singleton - use getInstance(); and using the initializer applies appropriate. In the second example, you can simply use the constructor and bypass the getInstance() method and no errors occur. They just leave it up to you, the developer, to use the getInstance(), method.

• How to get the static attribute by using its name as a string

  I have an app with about 100 boxes of single drop-down list (this is a requirement of the Government, I'm not that bad a designer) and I would like to define the choices in a single file separated like this:

  package components {}

  Import mx.collections.ArrayCollection;

  public class {choice}

  [Bindable] public static var A0310A: collection ArrayCollection = new ArrayCollection ([] collection
  {value: '01', label: 'Admission'},
  {value: "02", label: "Quarterly"},
  .. .snip...
  ([{value: "99", label: "NOT the OBRA required"}]) ;
  
  public static void getChoices(name:String):ArrayCollection {}
  var temp: ArrayCollection = collection?
  Return temp;
  }
  
  }//----------------end of class--------------------------------
  }//======================== end of package==============================

  I want to use it like this

  < my: ComboBox id = "mdscombo" tag = "A0310A" / >

  Where the definition of my: ComboBox includes the code like this

  var zz:ArrayCollection = Choices.getChoices (name);

  but I can not find any function that will allow me to do.  I don't want really clutter up the code by creating a name-> object mapping table.

  I had also considered using the XML data type, but I have the same question, unless I had all the choices under a single root (possible), but this could be a nightmare when debugging in typo XML file.

  Any suggestions?

  To answer your question, you can access static variables with a chain in this way:

  Choice ["A0310A"]

  However, you probably want to re-evaluate your design because this isn't a very desirable approach.

  What is the difference between Stratus and a Flash Media Server?

  When you use Stratus, all data is encrypted and sent directly client to client without touching a server. In comparison, applications by using Flash Media Server (or RTMP), data always passes through the server consuming both upload and download bandwidth of the server and the clients.  Stratus is a preview service which has its limits not including any programming of custom server and no remote shared object supports.

• Persistent var

  Hello

  I have a variable that I want to access at any time, as it does not change.

  I do not use any framework.

  One option is to:

  FlexGlobals.topLevelApplication.myVar

  But I do like it.

  What I do now is:

  public class Test

  {

  private static var _myVar:Object;

  public void Test (someObj:Object)

  {

  _mavar = someObj;

  }

  public static void get myVar (): String

  {

  Return _mavar;

  }

  }

  Then first set a value:

  test: var Test = new Test({test:'hello'});)

  Then everywhere else:

  Test.myVar to get the value

  But I don't like it either.

  What is the right way to do this please?

  The data changes... It is empty before calling the server and subsequently has the data.  This means that it is possible to write about it, and if you give global access and your project lives long enough and has enough developers, someone will.

  Seriously, just create your an object with your returned data once the data is returned, then pass these autour data to components that need it, as you would with any other model variable.

  If you feel like you absolutely needs good make a global static variable, I would suggest making it where it is initialized in the constructor and all the properties are read-only.

• Global var

  IN AS3, I want to use GLobal variables (not much) that can be consulted in any class and a place where the fla or any file as reported can be used and be ale to change the value of them anywhere.

  I can do this in AS3?

  One of the ways is to create a class with static properties methods and access them from anywhere in your application. It is called pattern Singleton (in a way).

  For example:

  package {     public class DataProvider     {          public static var property1:String = "blah";          public function DataProvider() {
  
            }
  
            public static function staticMethod():int {               return 45;          }     }
  
  }
  

  Use (from anywhere in your application):

  trace (DataProvider.property1); bla

  DataProvider.property1 = "aha."

  trace (DataProvider.property1); AHA

  trace (DataProvider.staticMethod); 45

• How to start the animation of the var

  I try to start my symbol of a var... but it just doesn't work, even if I gave him constant

  For example:

  var s2 = 35000;

  sym.getSymbol("second_arrow").play (s2);

  What wrong with it?

  Thank you

  The variable declared in a function are not accessible outside of it.

  So, better instead to declare the variable "s" inside the updateClock() function, declare it above the definition of this function, and things will work.

  See below:

  var s;

  var updateClock = function() {}

  ..........

  .........

  s = currentSeconds * 1000;

  ........

  }

  updateClock();

  sym.getSymbol("second_arrow").play (s);  "s" is now available

But when I resize the image, the change of shift. With small size reduction of compensation and resizing the offset increase more and more. How can I resize the image, keeping the same distance between the box and the text around it? Thanks for the help, Leo

  Open preferences. On the general tab, select "during the measurement: apply to the content. Now when you resize the images, the text wrap offset remains the same.

  For the images that you've already resized: select them, and then in the menu drop-down Panel, select "redefine the 100% scaling.
