• Listen to ObjectChoiceFields-based index

  HIi,

  I need to listen to ObjectChoiceFields based on the Index.

  I need to know how the default ringtone ObjectChoiceField work when we change the focus by trackball it gets the name of the targeted ring and play.

  is there a listener for it. I implement the fieldchangelistener, but it retrieves the selectedIndex property. but I need to retrieve the name of the targeted ring.

  

  Hey, I found the solution,

  just convert the field calling fieldChanged chain and you will get the name of the index targeted.

  FieldChangeListener listnr = new FieldChangeListener()

  {

  ' Public Sub fieldChanged (field field, int context)

  {

  String emringtoneS = (String) field.toString ();

• Implementing custom listener for ListField

  I'm trying to implement a listener for a custom field I created that would launch a new screen when you click on the field. However, nothing happens when I click on the custom field. I use BlackBerry Java plug-in for Eclipse, JDK 1.3 and JRE 6.0. All my code is attached. MyScreen.java contains the code where I'm trying to implement a function fieldChanged.

          // RichTextField is focusable by default. Here we provide a style
          // parameter to make the field non-focusable.
          add(new RichTextField("This is the speed bump screen!", Field.NON_FOCUSABLE));
      }
  
  }
  

  In addition, there is nothing in the ListField that will actually generate an event.

  Here is a simple extension to the ListField which will make "clickable".  In your FieldChangeListener you can use getSelectedindex to determine which line has the focus.

  Please ask if this isn't clear:

  public class ClickableListField extends ListField {
  
      public ClickableListField(int numberOfRows) {
          super(numberOfRows);
      }
  
      protected boolean navigationClick(int status, int time) {
          this.fieldChangeNotify(2);
          return true;
      }
  
      protected boolean touchEvent(TouchEvent message) {
          int x = message.getX( 1 );
          int y = message.getY( 1 );
          if( x < 0 || y < 0 || x > getExtent().width || y > getExtent().height ) {
                  // Outside the field
                  return false;
          }
          // If click, process Field changed
          if ( message.getEvent() == TouchEvent.CLICK ) {
              this.fieldChangeNotify(2);
              return true;
          }
          return super.touchEvent(message);
      }
  
  }

• event listener for when the Panel is open?

  is there an event listener for when a CEP Panel is open.

  I have a persistent Panel the onload works only when the Panel is opened for the first time. I want to keep persistent, but I want to know when the Panel is open again

  Maybe I've misunderstood something, because my English is bad. Unfortunately the listener for events at the opening of the Panel, I also have not found, I had to go through the back door.

• Listener for slider

  I have 8 sliders in an HBox, and I want to add a listener for each one that will allow me to know what cursor is somehow. Each slider represents a channel for a device, and even if I can add a listener which relays a number that represents the new value of the slider, he didn't tell me what cursor is. Although I can add an int value that represents the number of the channel of the cursor to its user data, it doesn't seem to be a way to extract the return type (number). The code looks like this:
  
  HBox hbox = new HBox (8); spacing of
  for (int i = 0; i < gain.length; i ++) / / for each output
  {
  [i] gain = SetLook (new Slider (0,100,0));
  gain .setUserData (i + 1); / / the number of input
  hbox.getChildren () .add (gain [i]);
  .valueProperty () .addListener (new ChangeListener < number > () [i] gain
  {
  @Override
  public void changed (ObservableValue <? extends number > ov, oldValue, newValue number number)
  {
  makeGainChange ((int) newValue.getUserData (), newValue.intValue ());
  makeGainChange (1, newValue.intValue ());
  }
  });
  }

  HBox hbox = new HBox(8); // spacing
  for(int i = 0; i < gain.length; i++) // for each output
  {
    gain = SetLook(new Slider(0,100,0));
    // gain.setUserData(i+1); // the input number
    hbox.getChildren().add(gain);
  
    // Add this:
    final int inputNumber = i+1 ;
  
    gain.valueProperty().addListener(new ChangeListener()
    {
      @Override
      public void changed(ObservableValue ov, Number oldValue, Number newValue)
      {
        // now pass the input number to your method:
        makeGainChange(inputNumber, newValue.intValue());
      }
    });
  }

• Creation of local listener for 11.2

  Version: 11g Rel 2
  Platform: Solaris 10
  2 node RAC
  
  Because of our custom requirements, we create our DBs CARS manually. Due to downtime, we create a listener for each DBs.
  
  If you are using dbca, all the below mentioned are the things in dbca. But if I used dbca I shouldn't know the existence of the file endpoints_listener.ora... and so on.
  
  Here's the scenario
  =============
  
  We already have our SCAN listener running on the port 31548.
  Now we create our local listener. So, I used netca to create the listener.
  
  

  DB name                 : HEWPROD
  Listener name           : LSNRHEWPROD (using netca to create this listener)
  Port                    : 25382
  Host name of Node1     : HWSTM348
  Host name of Node2     : HWSTM349

  NETCA added the following lines the listener.ora and endpoints_listener.ora
  

  1. listener.ora
  ==================
  LSNRHEWPROD=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LSNRHEWPROD))))                # line added by Agent
  ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LSNRHEWPROD=ON                                                    # line added by Agent
  
  
  2. endpoints_listener.ora
  ============================
  LSNRHEWPROD_HWSTM348=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hwstm348-vip)(PORT=25382))(ADDRESS=(PROTOCOL=TCP)(HOST=10.213.107.87)(PORT=25382)(IP=FIRST))))                # line added by Agent

  Question1.
  What is the endpoints_listener.ora file? What does the word "point limit"?
  
  Question2.
  After the creation of the earpiece using netca, we follow these steps on each nodes to get the listener service DB

  alter system set local_listener='listener_<instance_name>' scope=both;
  eg:
  alter system set local_listener='listener_hewprod1' scope=both;

  The statement above works despite the fact that he has none of these headphones with the name

  listener_hewprod1

  The real listener created by netca is LSNRHEWPROD. But how the (parameter LOCAL_LISTENER) command above?

  Yes, they can listen on the same port because each process uses a different IP address.

  The SCAN_LISTENER is listenening to a maximum of 3 different IP addresses.
  The local listener is listening on the virtual IP address, which is different from the SCAN LISTENER addresses.

  Do not hesitate if you have any questions!

• How do I listen for the change in the position of a node

  Hello
  
  I want to create a knot of thread/connection between two nodes of the scene. I want this thread node to be updated when one of the nodes is moving. In the common scenario I'd listen for change events in the nodes of the target of the post and update the thread:
  
  targetNode1.translateXProperty () .addListener (new ChangeListener < number > () {}
  public void changed (value of ObservableValue, oldValue, newValue number number) {}
  wire.setStartX (targetNode1.getTranslateX ());
  wire.setStartX (targetNode1.getTranslateY ());
  
  wire.setEndX (targetNode2.getTranslateX ());
  wire.setEndY (targetNode2.getTranslateY ());
  }
  });
  
  
  
  The problem is that the target nodes are children of a different container nodes (who are moving in fact). To listen for change events in the properties to translate target nodes does not work (their parent nodes are moving actually)
  
  Is there way of list of change in the overall position of the target relative to the scene nodes?

  That's right, it's not a super easy way to do. You need to connect listeners to each node in the parent hierarchy. The reason for which we do not have this feature built-in, is because it is extremely expensive (early versions of JavaFX 1.0 pre had "boundsInScene" but which was incredibly convenient, also completely killed performance). Do this for a few nodes is not a problem, but the fact for each node in the scene would be your 3 GHz machine to its knees :-).

  If you create a listener using NETCA, service will be created.

• The proper way to remove a listener for loader events

  Hello.

  I´d would like to know what is the rigth way to remove a listener for loader events?

  Like this?

  loader.contentLoaderInfo.removeEventListener (ProgressEvent.PROGRESS, onProgressData)
  loader.contentLoaderInfo.removeEventListener (Event.INIT, onInit)

  Thank you

  I find the best way to remove them is to make them the same way you added, replacing 'Add' with 'delete'... it seems that you did in your example.

• Why add a listener for an Event object?

  Hello

  
  

  I just read something that I do not understand in a book and, of course, I need help...

  
  

  stage.addEventListener (MouseEvent.MOUSE_DOWN, clicSouris);

  function clicSouris (pEvt:MouseEvent): void
  {
  var positionX:Number = pEvt.stageX;
  var positionY:Number = pEvt.stageY;
  monDessin.graphics.moveTo (positionX, positionY);
  pEvt.currentTarget.addEventListener (MouseEvent.MOUSE_MOVE, bougeSouris);
  }

  function bougeSouris (pEvt:MouseEvent): void
  {
  var positionX:Number = pEvt.stageX;
  var positionY:Number = pEvt.stageY;
  monDessin.graphics.lineTo (positionX, positionY);
  pEvt.updateAfterEvent ();
  }

  
  

  My question is what appens when I add an event listener for the event of the object? And why it does this?

  
  

  Following the logic with the AS3 display list, I thought that only Classes that inherit from flash.display.InteractiveObject might react to events from mouse (or keyboard).

  
  

  You can subscribe itself in any event an event? Am I wrong?

  
  

  Can someone explain to me this point because I'm really confused!

  
  

  Thank you!

  Basically function clicSouris is in itself an event listener and has pEvt as event event object argument.

  When you call .currentTarget pEvt it refers to the current object where the pEvt event is dispatched.

  Event.target and Event.currentTarget will always return the interactive objects where the event is currently being distributed.

  Now, I need to add labview program to this environment. I've implemented a solution to 'work' with the help of this forum. Thank you for this! Now, I need to do better (currently no timestamps, large delays, etc.).

  I currently have a web service deployed using http-get as input. My web service .vi is just passing the web entrance to shared variables that are then questioned in real measurement program. Reason is that when I put the measurement program directly to the web service, it does not (something about rights and dependencies). Measurement program includes one third of the owners (Instron) drivers. Also I would not direct access via the network to our mechanical testing device potentially dangerous.

  Now, I want to change the message from the web services .vi commensurate .vi. Currently I have a loop of 10ms to query for changes in the shared variable. Is there a better way to do this? I thought create a listener to the shared variable change events.

  In addition, if you have any ideas (preferably, working code example) how to make the interface between labview and TCP-JSON I would really appreciate it.

  BR,

  Juha

  Currently in LabVIEW, the only way to create an event listener or event NSV is to use the DSC toolkit.  Most of the time the DSC is a very expensive tool that simply encapsulates the functionality that is built into the motor of the PSP and OAS and which is accessible to anyone who can program in LabWindows/CVI.

  If you want to collaborate, I would like to create a small library of LV that would create a base SV events using a vi LV reminder or possibly passing return user LV event which is how works the DSC toolkit.  I asked OR several times to explain how do this and they're very tight discreet about it.  I guess that they do not want to give users LV less reason to buy the DSC.

• Will there be a listener for the open calendar appointments?

  I am trying to find a way to listen to the calendar when the user

  Open an appointment for viewing.

  I know that I can listen to add pim event but is there a way to tell when the user

  Open an appointment?

  This is not currently supported.
