Events and listeners between custom classes

• creating custom events and listeners

  I want to create my own event and a listener for a process in the background. This isn't an extension of a listener to, for example user intervention.  What I could find, it seems I can't extend EventObject in j2me. I tried to work around that by the presence of a field 'status' in my background thread, but it makes no sense because I can't respond to the thread how to fill. I am new to the development Java and bb, so I don't know that there's something I'm missing, but the search for these tips for the 'events', etc is nothing. Any thoughts? More info, I can provide?

  OK, it worked, except that I had to implement my own observer / Observable classes, essentially to copying the standard and by replacing a piece of code that calls the method toArray() vector. The code compiles now, but I can not yet say that it works. :^/

• 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.

• Global events and global event listeners does not work!

  I don't know who to ask if I have questions about knowledge base articles so I'll post here.

  I want to push the alert as how dialog box integrated calendar alerts to users. I understand that I need to use the globalevents and listeners, so I studied it in the knowledge base article below:

  http://supportforums.BlackBerry.com/T5/Java-development/global-events-and-global-event-listeners/TA-...

  However, when I run the code, it does nothing. The way it is set up, it should display messages ("received event, sending accused of receipt and acknowledgement received"), but nothing happens on my Simulator, once I have 'fire' of the global event. Help, please!

  No problem. We were all there at one point.

  Each of these files has a main method that is your entry point to the application. Since everyone has one, they all have two need to have their own projects.

  For example, to create a new project for each of these files in Eclipse (or JDE; Eclipse preferred) and drop the code in., and then run the two projects on the Simulator.

  Once both applications on the sim card, you can then view the interaction between the two applications.

• 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.

  Hello

  Does anyone know the real difference between Pseudo-classes and pseudo-element?

  The two are very different, but I can't yet tell them apart.

  Pseudo-elements are so-called because they are not real HTML elements - for example there is no HTML didn't call first line tag, but using CSS you can apply a style to the first line of a paragraph, for example using: first-line. A pseudo-class is called a class because it does not select a property of an HTML tag (e.g. a: hover, targets of the HTML tag), but because the hover is not a class attribute, the designer has added to the markup, it is called 'Nick'). Using double colon for Pseudo-elements is the new syntax (standard CSS3) and is not always understood by all browsers yet, sometimes, you need to use a single colon.  The double colon comes to more easily differentiate Pseudo-elements (:) and Pseudo-classes (:).)

• Difference between 4-10 and 11-15 custom object

  Anyone has an idea about the difference between custom objects 4-10 and 11-15. In the admin model, there is a distinct privilege for these two so wonder.

  Hello
  In R16, custom objects are grouped into 3 levels

  (1) * custom objects 1-3 *.
  2) oppose custom 4-15
  3) object custom > 15

  (1) custom objects 1-3:
  -These custom objects has many-to-many relationship with the main types of records and other custom objects

  (2) 4-15 custom object:
  -These custom objects in a one-to-many relationship with the main types of records.
  -They are further divided into 2 parts: 4-10 and 11-15
  - So when you activate all objects between 4 and 10, all of the objects from 4-10 will be activated and is also true for the 11-15.

  (3) items custom > 15:
  -To allow these objects, that you must check your Oracle design and it is available only for single tenant, not for multi tenant clients.

  Hope this information is helpful to you

• Difference between events and projects

  Hi all

  Looking for an answer simple because I am currently working on what differences or purposes are events and projects in iMovie 10.

  I feel that I duplicated a large number of events and projects, because they share the same name.

  The events of projects collect media imported into a project. These events make media accessible from other projects, while you are working on a different project.

  When the project is opened, you experience media used in the project in another way too. But the media are not duplicated.

• What is the difference between a class and an extended class?

  Hi, can someone please help me understand how the working classes?  I see span classes in the HTML but do not understand the meaning, and its creation a few problems.

  I have a text with a link Hypertext and need to style the text of the link. I have implemented the css rules to style the text - they are controlled by a class ("link_red").

  If I select the text for the link and apply to a class (through the property inspector), here is the result: < a href = "mypage.shtml" class = "link_red" > here < /a > text - but the style for the link is not applied. "

  If I edit the html code to assign the class as a span class, here is the result: < span class = "link_red" > < a href = "mypage.shtml" > text here < /a > < / span > the style for the link is perfectly applied.

  I have a lot to assign different styles different link to and its obviously much quicker to just select the text and assign the appropriate class, rather than waste his time adding the tag span, so that I could do with an understanding of this text.

  Thank you!

  In fact, I see that I didn't really answer your question.

  If I select the text for the link and apply to a class (through the property inspector), here's the result: text here - but the style for the link is not applied.

  It probably means that there are a few other CSS on the page which is the substitution of your class and avoiding the red color cast.

  If I change the html code to assign the class as a span class, here's the result: text here for the link style is perfectly applied.

  Then, it is a curious observation - we would need to see the actual page and the CSS to understand why it's happening.

  I have a lot to assign different styles different link to and its obviously much quicker to just select the text and assign the appropriate class, rather than waste his time adding the tag span, so that I could do with an understanding of this text.

  In fact, the best way to proceed is to use a descendant selector that can be applied to multiple links at the same time.  For example, if you have.

  div1 has {color: red ;}}

  div2 has {color: blue ;}}

  Div3 has {color: green ;}}

  You can style each link in each of these three divs.

• 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.

• How can I 'include' a file different php depending on time? Work on a 'Happening Now' page for an event and the need to plan a different content to load as the day continues. Thank you!

  Work on a 'Happening Now' page for an event and the need to plan a different content to load as the day continues. Thank you!

  The event has class sessions all day (3 days). I would like the page happening now to show what classes are going on right now and what is coming up next. I was hoping just to separate configuration files and load them when necessary, but open to all suggestions.

  PHP has a powerful set of date and time functions.

  To do this is to create a DateTime object and then use conditional logic to include the files you want. A better way would be to keep the details in a database and use the time to retrieve and display the details you want.

  A DateTime object using:

  $now = new DateTime();

  $hour = $now-> format ('G'); This gives you time to the 24 hour clock.

  If ($hour == 13) {}

  It is between 13:00 and 14:00

  } else if ($hour == 14) {}

  It is between 14:00 and 15:00

  } ....

• create a listener for a custom class?

  I have a custom class that loads a couple of XMLs. I create an instance of this class in another class and I need to know when it is done so that I can then call a function of loading in this class of parent.

  How can I do this?

  pls know me if I need to explain differently.

  Thank you!

  When you create your instance of the class:

  ///////////////////////

  classinstance.addEventListener ("xmlloadingcomplete", f);

  private void f(e:Event):void {}

  //

  }

  ////////////////////

  and in your xml, class loading, loading is complete:

  this.dispatchEvent (new Event ("xmlloadingcomplete"));

• SQLite, from SQLinstructions to a custom class

  I'm working on an AIR of FB app.

  I have a file with a source main.mxml in main.as file.

  My main.as file becomes very swollen with SQLinstructions. I want to switch to a custom class, but I do not know how to proceed.

  I found an example of a package on this page: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/data/SQLConnectio n.html #begin)

  on a 3rd down.

  The example above, that's exactly what I want to do, but I do not know how to adapt it for use in my file main.as beyond to import the class and instantiate. How can I assign my values in the class file? How to use the class to load up the dataProvider, etc...

  In addition, in the example above, the class extends Sprite. This sounds like it is for a Flash application. I always extend Sprite in Flex 4? I made a couple of simple events, data transmission to the main application with the Flash.Events.Event, so using Sprite causes some confusion.

  In a previous post, Amy suggested using Robotlegs. I think I need to get a handle on the use of Flex before I explore other architectures. I'm just not that sophisticated.

  OK, a small example

  a new package called utilities, then a new called class class actionscript DatabaseManager

  package utilities
  {
       import flash.data.SQLConnection;
       import flash.data.SQLResult;
       import flash.data.SQLStatement;
       import flash.filesystem.File;
  
       import mx.collections.ArrayCollection;
  
       public class DatabaseManager
       {
            private var sqlConnection:SQLConnection;
            private var stm:SQLStatement;
  
            public function DatabaseManager()
            {
  
                 //connect to database
                 sqlConnection = new SQLConnection();
                 sqlConnection.open(File.applicationStorageDirectory.resolvePath("whatever"));
  
                 //create tables if not exist
                 stm = new SQLStatement();
                 stm.sqlConnection = sqlConnection;
                 stm.text = "create your table here";
                 stm.execute();
  
                 //create more tables
                 //...
            }
  
            public function getThings():ArrayCollection
            {
                 stm = new SQLStatement();
                 stm.sqlConnection = sqlConnection;
                 stm.text = "your query";
                 //...
            }
  
            public function addStuff(stuff:Object):int
            {
                 //...
            }
       }
  }
  

  then in your main file, you need to import

  import utilities.DatabaseManager;
  

  instantiate the class, it connects and creates tables

  private var myDB:DatabaseManager = new DatabaseManager();
  

  then to use it

  var listFromDatabase:ArrayCollection = myDB.getThings();
  

  insertid = myDB.addStuff(thingToAdd);
  

  hope that gives you an idea

• To access instances of a custom class that extend box

  Hello

  Forgive me if I couldn't find an answr my question with various searches in the forum, but I'm not an expert and I can't even find the right words for the search.

  Here's the problem:

  I created a class (called LAlgExpression) which extends the class box. Instances of the class are added in a box, and I tried to access these instances using mouse events.

  Now, I can actually access my custom class instances by using the properties target and currentTarget of the events, but unfortunately they are considered as belonging to the Object class and not to the class LAlgExpression which make it impossible to use all the methods I've defined for LAlgeExpression because the compiler tell me that I am trying to use on an object a method that is not defined for the class Object. What's funny is that when running when I try 'event.target is LAlgExpression' it returns true, but I don't know how to convince the compiler . It's as if the instance that I have on the screen is an object and a LAlgExpression, but the compiler will not let me treat as LAlgExpression, but only as an object and I don't understand why.

  is there a way to force the compiler to consider LAlgExpression, something he sees as an object?

  Thank you very much in advance for your help

  var obj:LAlgExpression = event.target as LAlgExpression;

  or

  var obj:LAlgExpression = LAlgExpression (event.target);

  then call methods on obj and it should go.
