• 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!

• 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).

• 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.

• 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.

• 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

• How to inherit the properties of the base class?

  Hi all

  I have a doubt. Can someone remove this doubt?

  Steps to follow:

  (1) I created a movieClip & named MyComp

  (2) I export this movieclip in actionscript. The class name for this movieclip is MyComp.

  (3) then dynamically I created 5 instance of this class and added to the stage.

  (4) now I need to change the width of MyComp. He should think about a previous 5 instance too.

  I tried like,

  I created MyComp.as file in the same place. I tried to inherited DisplayObject properties Width.

  Example:

  At the time of creation, I have a movieclip in my library that contains a rectangle shape... IM adding 5 This movieclip instance in the stadium.

  After that, I get in a movieclip and im increasing the width of this movieclip by increasing the width of the shape. He'll get reflected in all cases...

  I need this thing in actionscript... is it possible?

  Thank you...

  You can't do what you're trying to make the way in which you are trying to do.

  I've included a code here (pure AS3 without chronology or library) that you may be able to adapt to your needs

  Basically, I created a static property (_rectWidth which controls the width of the rectangles) on the MovieClip class that contains the rectangle and a render() function that redraws the rectangle to the right width. Note You must call render() after setting a new width to see the rectangle drawn to the new width.

  Then in the main class, I create 5 rectangles to the posts and random colors.

  The main class also listens to the "arrow up" and "arrow down" to change the size of the rectangle. Note: I change the size of the rectangle and then worked for all classes of hand children (all of which are the RectMC) and call render();

• 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:

  Any help will be appreciated.

• Extend the custom class

  I made the transition to AS3 two years ago, but I always carry with me old habits AS2. Could someone please help me understand how to extend a custom correctly class.

  I have a bad habit to put most of my code in a file .as (Document class), but I use some custom time classes. I am tring to understand, this is how I would extend to a class of this type:

  public class ClipDragger {}

  private var _clip:MovieClip;

  public void ClipDragger(clip:MovieClip) {}

  _clip = clip;

  _clip.buttonMode = true;

  _clip.addEventListener (MouseEvent.MOUSE_DOWN, drag);

  _clip.stage.addEventListener (MouseEvent.MOUSE_UP, drop);

  }

  private void drag(event:MouseEvent) {}

  _clip.parent.SetChildIndex (_clip, _clip.parent.numChildren - 1);

  _clip.StartDrag ();

  }

  private void drop(event:MouseEvent) {}

  _clip.stopDrag ();

  }

  }

  For example, I would like to add a MOUSE_MOVE listener and also add actions in drag.

  Could someone guide me in the right direction please?

  package {}

• Laber property of the RadioButton class

  I would like to learn use "Flash CS4 Professional 3.0 ActionScript Language Reference" and I beginning with this example, the question:

  Why the label property is not listed in the properties of the RadioButton class?

  The various components label property is inherited from the LabelButton class.  If you select "Show inherited public properties" in the beginning of this article, it will be included with the rest of the RadioButton and other inherited properties.
