• Unable to make a call to the custom class

  Hi all

  I train to call the custom since the screen as below class, but its not picking up the custom class features and gives the result, I don't know if something is not in the below class or the way I call this method.

  package com.ge.bbcalendar;

  Import net.rim.device.api.ui.Color;
  Import net.rim.device.api.ui.Graphics;
  Import net.rim.device.api.ui.component.LabelField;

  public class TestClass extends {LabelField
  Private boolean brought;
  private string text;
  style long private;

  public {TestClass (String text, long style)

  Super();
  This.Text = text;
  This.style = style;
  }

  protected void onFocus (int direction) {}
  focused = true;
  Invalidate();
  super.onFocus (branch);

  }

  protected void onUnfocus() {}
  concentrate = false;
  Invalidate();
  super.onUnfocus ();
  }

  protected void paint (Graphics graphics) {}
  graphics.setColor (Color.WHITE);
  graphics.setBackgroundColor (0x544E4F);
  If {(targeted)
  graphics.setColor (Color.BLUE);
  }
  Graphics.Clear;
  Super.Paint (Graphics);
  }
  }

  Called as of the screen

  SerializableAttribute public class NativeScreen extends form {}

  final cas15 TestClass = new TestClass("",LabelField.FOCUSABLE);
  }

  What is the problem above?

  I suspect that your problem is the LabelField don't think it has any text to display.

  You really need this, I think

  public TestLabel (String text, long style) {}
  Super (Text, FOCUSABLE);

• ClassCastException in the custom class loader

  I created a custom class Leon.
  
  CCL ClassLoaderDemo = new ClassLoaderDemo(); assume that it works very well
  CLAS class = ccl.loadClass ('com '' ' MyObject');
  
  com MyObjectSuperClass o1 = (com. MyObjectSuperClass) clas.newInstance ();
  
  Now I want to get the object responsible for MyObjectSuperClass which is super class if MyObject. But I'm getting the following exception
  
  Exception in thread "main" java.lang.ClassCastException: com. Com cannot be cast to MyObject. MyObjectSuperClass
  
  Help, please.

  My requirement is the class MyObject needs to be loaded by my client class loader. If you say that let the superclass (MyObjectSuperClass) be in the class path and let the class system charge charger, then usually it be a problem

  No, it's exactly what you want.

  MyObject loaded by the custom class loader, its super class loaded by the system class loader, I will be able to cast then.

  Yes, you will be able to cast to the upper class, then.

  It is not similar to the statement "MyObject loaded by the class loader and custom class system are different and we cannot throw.

  No, it isn't. your confusion is due to the fact that you don't seem to understand that you can have a class hierarchy that spans the Chargers of classes. This should be obvious because each object hierarchy extends eventually object, which is always in the system class loader. Therefore, you can always convert any instance of any class loader "Object". in the same way, you can have MyObjectClass in your chargers personalized classes and MyObjectSuperClass in the system class loader. You can instantiate an instance of MyObjectClass to aid reflection on your custom class loaders and assign it to a reference of the type MyObjectSuperClass. This is how pretty much any plugin system is implemented (the API is in the 'main' class loader and the implementation is in a nested class or custom ClassLoader).

• Listen to the event within the custom class

  I created a custom class that publishes on a webpage to authorize a user. How can I listen to an event within the custom class?

  It is my code in my main class.

  var customClass:CustomClass = new CustomClass();

  var testingString = customClass.authorize ("[email protected]", "password");

  the fuction "authorizes" within the customClass looks like this:

  public void authorize(user:String,_password:String):void

  {

  jSession = new URLVariables();

  j_Loader = new URLLoader();

  jSession.j_username = user;

  jSession.j_password = password;

  jSend.method = URLRequestMethod.POST;

  jSend.data = jSession

  j_Loader.load (jSend)

  }

  How can I trigger an event in my main class once the j_Loader triggers Event.COMPLETE?

  You can raise an event using the dispatchEvent() function.

  In your main class, you assign a listener to the event the CustomClass distributes when there are.

• I need help which extends the MovieClip class

  I want to add a property to the MovieClip class. I have just a bunch of clips that are placed on the stage by reading an XML file and creating lots of clips from the information in them. Now, I need to know what MovieClips were created under previous clips, and I think that the best way to do it would be extending the MovieClip class and add a property of the order.

  I have some problems however: I do not know how to set or get this property of order within the main Clip, I do not know how to put this clip in my movie, and I don't know how to create them dynamically (just do something like var myNewObjectOfExtendedClass: myExtendedClassName = new myExtendedClassName?)

  This is the code that I have on my category Advanced, called Expando.as:

  Expando class extends MovieClip {}

  _order:Number private var;

  public function get command (): number {}

  return _order;

  }

  order(nOrder:Number):Void {} public function public set

  _order = nOrder;

  }

  }

  I recommend that you see for the tutorial of the tree in order to see how this should be done.  I think you are missing some basics.

• To access the event listeners in the custom class

  I am a construction and film using the classes customized for the first time. I built a custom class and bound a clip in my film for her so that the color of the text in the video will change when he is overthrown. I have 10 occurrences of this clip in the film, so it saves me a lot of code. Instead of writing 10 to ROLL_OVER event listeners and 10 more for ROLL_OUT (as I have done in the past), one for each instance of the clip on the scene, I wrote now event listeners and the corresponding functions in the custom class. So far, so good, everything works fine. When I ride above and outside on one of the 10 instances of the clip on the stage it changes color. See code attached.
  
  However, according to what is happening in the film, that I sometimes need to turn off the headphones of events on one or more video clips. So, I wrote the code in the movie itself to remove event listeners of the instance of the clip that I need to disable. See code attached.
  
  But, alas, it does not work.
  
  I get this error:
  ReferenceError: Error #1065: Variable turnWhite is not defined.
  
  I thought that by the 'public' method in the custom class, I would be able to call from the film, but I do not. Any help or advice would be greatly appreciated. Thank you very much.

  Ned, thanks for your help. I was able to understand. Your code has been helpful, and I've used something similar to what you suggested.

• Extend the CellRenderer class

  I tried to extend the CellRenderer existing lightly change the behavior. However, I am having a very difficult time to do without actually looking at the CellRenderer class code. Its quite difficult to understand what methods override and what are the variables containing the required data. Is it possible to access the code? I do not use FlashBuilder.

  Thank you.

  Hey,.

  I wrote a sampling program that does what you need except im trying to figure out how to make the box event listeners. working on that now, but it's the code that should go you. I have class one main and one cell renderer. You got the general idea. I think the only thing that you missed the width and the implementation of the check box. When you use the this reference, you are referring to the cell itself and not the box. I think you might have mixed up who. This reference is to the current class as a whole and not only control access. Here is the code:

• Properties of the label and the custom class

  I want to do the following persistent: < mx:Label useHandCursor = "true" buttonMode = "true" mouseChildren = "false" / >

  I tried to create a custom class that extends the class Label, but we can't get the syntax right.

  protected override?

  buttonMode = true;

  I don't think I want to replace a function.  It seems to me that I want to override a property or attribute of the Label class.

  Can someone give me advice?

  Hello

  As you Lable with the default property {useHandCursor = "true" buttonMode = "true" mouseChildren = "false"}

  I extend the label, you can do it directly in the constructor by setting

  -Custom label class-

  package
  {
  Import mx.controls.Label;

  SerializableAttribute public class CusLbl extends Label
  {
  public void CusLbl()
  {
  Super();
  super.buttonMode = true;
  super.useHandCursor = true;
  super.mouseChildren = false;
  }
         
  }
  }

  --------------------------------------------------------------------------------

  You can use directly in the application or in any other container with the default property;

  See attached the file if necessary.

• import a class: how many ways are there? CFC, import, extend the base class

  How many ways is there to import a class and am I confused

  1 screen/public class extends MovieClip

  This inherits all the properties and methods of the MovieClip class so WHY again do we use: import flash.display.MovieClip;

  Import something else or just made the job twice

  2 import flash.display.MovieClip - so no need to extend (repeat me once again - see 1)

  3 CFCS: connect to a CFC

  4. stir in a SWF with a meta tag

  5. in the properties panel menu - add a class as a base class

  OMG - a bit confusing

  You can only "extend" another class if the compiler knows where he is.

  The import statement is only by the compiler to find the class on your hard drive.

  It is not "import" of the entire class in the sense that you import a BMP in Photoshop.

• To access the properties of the custom class

  Hello again! Nevermind, I got display list order because it has me even more trouble :)
  
  I have several items stacked from the other (boxes) and you want to calculate the height of all the underlying boxes for each box. Each box is an instance of a "Kiste"-custom class that has a property "hoehe" (height). "." Usually, I can access this property from anywhere and it works fine. But in the following case, it won't. The alles.getChildAt(j-1) works fine with all other assets, but not with custom properties that I defined in my class?

  OK, get it myself... Type cast!

• Best way to insert data into instances of the custom class

  Hello.
  
  I have created a custom class (mySuperClass) in an .as file, defined constructor methods, properties, and the get/set. Now in the main .fla I must declare a large number of instances of this class and complete each property. The 'proper' method, I guess, would be to:
  
  var super1:mySuperClass = new SuperClass();
  super1.setProperty1 ( value1_1);
  super1.setProperty2 ( value1_2);
  ...
  super1.setPropertyN ( value1_N);
  
  ...
  var superM:mySuperClass = new SuperClass();
  superM.setProperty1 ( valueM_1);
  ...
  superM.setProperty1 ( valueM_N);
  
  However, with large quantities of variables and information that share the same basic characteristics, I feel always attempted to do through a cycle of dethrone. In that case, I'd probably build tables with the properties to complete.
  
  So I want to know is how would you guys do it? Are there other ways to do it?
  
  Thanks in advance.
  
  

  Well, the example is based on an object that has a datamodel and which can be any object of course. Now, assuming that the data come Let's say an xml file, I would use a function as the code to generate a collection of objects.
  Edit: so the StoreItem instances are created on the fly and saved in the collection

• Iterate through the custom Classes?

  Hello

  Suggests, I have a class with public properties as

  Class person {}

  public var address: String;

  public var name: String;

  public var fathername:String;

  etc etc.

  }

  Now I want to iterate over them in a simple way as

  for {(var clé: string en personne)}

  trace ("property is" + key + "and the value is" + person [key]);

  }

  But does not allow it to do with the AS3 Classes

  Now, I want you guys to suggest me what would be the simple and best way to iterate over them, because I don't want to do so much if (else) about it.

  Thank you

  You can try using the describeType() method:

• AppModuleImpl methods of the class returns the custom class types, not called.

  Hi all

  Methods of the class AppModuleImpl custom types of class, not called when you access through back links.

  OperationBinding operationBinding = bindings.getOperationBinding("getInstanceNameO"); where 'getInstanceNameO' is a method AppModuleImpl returns a class serializable type.

  Any help will be appreciated.

  OI_testBean.goInstanceName_methodCallNew (OI_testBean.Java:99): this line is the call of method appmoduleimpl: OperationBinding operationBinding = bindings.getOperationBinding("getInstanceNameO");

  Looks like 'bindings' is null.

  How to retrieve variable 'bindings '?

  Where is the OI_testBean.goInstanceName_methodCallNew () method called?

  If this method is called from the method call activity, you create pageDef in his name and add getInstanceNameO
