ClassCastException in the custom class loader

• 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.

• 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);

• 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.

• 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.

• 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

• 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 {}

  import flash.display.MovieClip

  SerializableAttribute public class ClipDraggerExtension extends ClipDragger {}

  private var _clip:MovieClip

  public void ClipDraggerExtension(clip:MovieClip) {}

  Super (clip);

  _clip = clip;

  add whatever.

  replace all what

  This error message is misleading, but you have twisted code.  Try:

  package

  import flash.display.DisplayObjectContainer;
  import flash.display.DisplayObject;
  public class traceDisplayList
  {

  public void traceDisplayList(kontainer:DisplayObjectContainer,_indentString:String=""):void

  private void traceF(kontainer:DisplayObjectContainer,indentString:String=""):void {}

    var child:DisplayObject;            for (var i:uint = 0; i < kontainer.numChildren; i++)            {                child = kontainer.getChildAt(i);                trace(indentString,child,child.name);                if (kontainer.getChildAt(i) is DisplayObjectContainer)                {                    traceF(DisplayObjectContainer(child),indentString + "");                }            }

• Customize the process of downloading files by replacing the UploadedFileProcessor class

  12.1.3 Jdev

  Hello

  I have an af:inputFile on the page and want to customize the file loading process by replacing the class org.apache.myfaces.trinidad.webapp.UploadedFileProcessor together with the < downloaded-file-processor > element in the config.xml configuration file - Trinity.  This is because we want to save the file directly on the database rather than store them in temporary storage.  No samples of writing a custom class?

  I understand in the custom class, it must implement the UploadFileProcessor interface and override the method:

  processFile (object request, file UploadedFile)

  What is the motion of object?  And how to treat?

  All advice is appreciated.

  Thank you

  -Mina

  Thanks Timo.  Excellent suggestions!  I found the class that implements UploadedFileProcessor is org.apache.myfaces.trinidadinternal.config.upload.CompositeUploadedFileProcessorImpl.java

  Thank you

• How to operate system class loader in blackberry?

  How the system class loader in blackberry?

  I have a few questions

  * can I load a class with the name of spesific file. for example, I have a file "myclass.txt" at cod. and it's a class file. I can load it?

  ("can I load class as follows: Class.forName("/myclass.txt ");

  * I can load only of class which is the name ends. class. This is a must for file names ends with ".class"?

  * I use Class.forName to load classes. is there another way to load?

  * If a class has a function that is not in the device OS, I can not load. But in the BlackBerry OS does not run applications. However, the OS should throw exception when I try to load this class. is it not?

  The way that J2SE load classes/functions is "properly" so if you tried something like that or used ClassLoader it would be just 'see' setNonSpellCheckable if she was called.

  On BlackBerry, that it is responsible when loading of the entire class, so when loading SpellCheck the native (no developer access) ClassLoader reads everything and said ' wait, I have not this call here, even if it might not get called I don't want to take the risk. "

  Who is?

  A workaround would be something like making a separate file of COD with the device's specific function calls, and then to call, that way if it is not supported on this version of the API that it doesn't get coded into the device specific COD file.

• EventDispatcher on custom class

  I tried to create an event dispatcher in a custom data transfer object class. This is a simple class, and I don't know how send an event. I tried that extends the EventDispatcher class, but that doesn't seem to work either. Any help would be greatly appreciated.
  I enclose the application code and the custom class. It should work from what I've read, but I can't do the application to intercept the event.
  APPLICATION
  <? XML version = "1.0" encoding = "utf-8"? >
  "" < mx:Application xmlns:mx = ' http://www.adobe.com/2006/mxml ' creationComplete = "initThis ()" layout = "absolute" > "
  < mx:Script >
  <! [CDATA]
  Import mx.controls.Alert;
  
  private var _tester:TestClass = new TestClass();
  
  private function initThis (): void {}
  addEventListener (TestClass.TEST_ACTION, onTestHandler);
  }
  private void onTestHandler(event:Event):void {}
  Alert.Show ("send event");
  }
  []] >
  < / mx:Script >
  < mx:Button = "312" x y = '150' label = "Button" click = "{_tester.testEvents ()}" / >
  < / mx:Application >
  
  CLASS
  package
  {
  import flash.events.EventDispatcher;
  import flash.events.Event;
  
  SerializableAttribute public class TestClass extends EventDispatcher
  {
  public static const = "test" TEST_ACTION:String
  
  public function testEvents (): void {}
  dispatchEvent (new Event (TestClass.TEST_ACTION));
  }
  }
  }
  

  However, I found an alternative, although I still don't understand exactly. If I add the event listener directly to the class in the creationComplete apps (initThis()) as:

  _Tester.addEventListener (TestClass.TEST_ACTION, onTestHandler);

  The application intercepts the event, even if she isn't really enforcement, he is now? This is the class real, right? I'm confused about this.

• Interpolation in custom class

  I am a newbie in flash/actionscript related. I created a towers of hanoi video clips solution using the motion tweens. It worked great all when the action script containing the creation of Tween existed on what I think is the clip of root (in my FLA file action script window).
  I tried to move the solution of hanoi in a custom class (which extends from EventDispatcher) and now the interpolation "does not. I reinforced with my code with the debugger and added a lot of tracing instructions and I'm sure that all the arguments for the Tween constructor are correct.
  
  _currentTween = new Tween (_movingDiskMc, "FLF", Regular.easeOut, _movingDiskMc._y, _yMin, _duration);
  
  Is there something fundamental, that I'm missing? Is the frequency of images, a problem with the custom class? _Duration above value is 5.
  
  THX
  
  -Kurt

  Ahhhh... after a further examination found that my "onMotionFinished" event handlers have been called, but in the debugger, the scope is the interpolation my class of Hanoi. Went wrong

  found the discussion in the help topic regarding the scope of event handlers and using things 'suggested strategy' work very well now
