RemoveElements/InsertElements

Similar Questions

• removeElement() question

  Is there a better way to remove a jacks and more removElement()?  I add the component with addElement(), removeElement() does not actually remove the memory component, only the display.  I'm not terribly worried, unless someone load a lot of components that have many graphics, text, styles, skins and associated as files.

  Thank you.

  Hello

  After calling removeElement(), which returns IvisualElement, you can catch this object and make it null.

  Hope this helps

• Adding field in the item table programmatically

  Hello.

  I'm doing a generic 'engine' for generating test reports/certificates.

  I made a custom data containing type report item, I used to do a local variables array of report called table of report item items.

  The data type contains generic areas (chain of title elements, a string of type item, etc.) and a container of the element data.

  The idea is to increment the array of items to report with report items and then fill the data container of the element with the fields of for example a Table element container.

  Either that, or just add a field in the report item with the data Table element type.

  But I can't find a way to add fields programmatically in a container.

  Anyone know if this is even possible?

  Found!

  Using from one stage of education, who points to the array of report items using the NewSubProperty method.

  Finished with the following statement:

  Parameters.Report_Element_Array.InsertElements (GetNumElements (Parameters.Report_Element_Array), 1, 0),
  Parameters.Report_Element_Array [GetNumElements (Parameters.Report_Element_Array)-1]. NewSubProperty("Element_Data",PropValType_NamedType,False,"NSE_Report_Table",0)
  
  

• Complete the table of reference

  Hello

  What I want: complete a table that is inside a container and named function of input parameters.

  What I tried:

  I created an object reference, Locals.obj_temp, which stores the set I want to fill the inside of the container.  I seem to be able to get the number of items, define the limits of the table, insert items, etc., but I can't figure out how to put values in there actually.

  I learned today that I can use ' * ' for dereferencing the ref of the object, so I use

  InsertElements(*Locals.obj_temp,"[0]",1),
  
  

  to add an item correctly.

  But, I don't know how to make the value I want it to be, and not not not the default value zero as shown in the picture.

  for what it's worth, this is how I make the new table inside the container and obtain a reference to it.

  Parameters.UniqueFCs.NewSubProperty(Parameters.UniqueFullTable[0][Locals.m],PropValType_Number,True,"",0),
  
  Locals.obj_temp = Parameters.UniqueFCs.GetPropertyObject(Parameters.UniqueFullTable[0][Locals.m],0),
  
  

  

  I found a way to do it.

  I created a temporary table as Locals.Arr1 and clone to the container parameter I want.

  For all of you who found this thread, I have

  Locals.Arr1 //my table temp I empty at each iteration of my loop for external
  
  
  /*
  code that fills Arr1
  */
  
  Locals.obj_clone = Locals.Clone("Arr1",0),  //create a clone of obj of Arr1
  
  Parameters.UniqueFCs.SetPropertyObject (Locals.name_temp, 1, Locals.obj_clone), //copy Arr1 table in my output tray (my container is called UniqueFCs)

• Capture engine pointer to external application

  Hello

  I need a program to change a Global sequence running. Simplify, I need to change a Boolean Global with an external application (in c#). If someone has done something similar, I would like to know how.

  So far, ive tried to save the object pointer in the configuration file, through TestStand and an another c# application, but it was not good because it save it as an object com I now try to use Remote Access Services to launch a service (with the current engine) with TestStand so my application can communicate with the engine via remote access.

  I tried my client-server without TestStand and works very well, but I can't grow if I run the application server through TestStand.

  I know more ways to capture the pointer of the engine... Any idea?

  Daniel

  Probably the best thing to do would be to use a queue of TestStand or notification for transmitting data between processes. Using the step type, if you start the name of a queue with a ' *' character then the queue will be global for the entire machine. To access the queue of your external application programmatically, create an instance of the teststand engine and call GetSyncManager() on this topic with the name of your queue (i.e. it must begin with a ' *' character). Then use synchronization to TestStand API with returned Synchronization Manager Manager to get the existing queue and access. Notifications can also pass data and can be used in the same way. You can store the global variable itself by reference to the queue and get the external application using Dequeue in a TestStand object reference variable (pass false for the Microsoft.SqlServer.Management.Sdk.Sfc.ISfcCollection.RemoveElement parameter so that it remains in the queue for the life of the queue). See the teststand help file for Synchronization Manager and the queue of API information. You can create a TestStand object reference variable to store the corresponding element using Engine.NewPropertyObject (). Then once there, simply call GetValueInterface and access the value returned as a PropertyObject himself.

  Hope this helps,

• Listener GPS problem

  Hi people,

  In collaboration with 4.2.1 on the 8800 Simulator.  My application is currently composed of two separate applications, app UI to obtain/view the information and a 'replication' application that communicates with our backend. I want to be able to include location on request of the user data (in the application user interface) and once it is updated, have replication app send it to the server. I have this work especially to my satisfaction, but the following problem: when I close the application user interface, any incomplete GPS please never finished. It seems that my LocationListener is not registered, or maybe the listener Thread is killed the closure of the part of the user interface. I don't expect that the instance is stored in the runtimestore and the object that is saved as the listener is always valid. Here's how I set it up:

  App of the user interface, the following is performed from a menu, click:

              GPSUpdater gps = GPSUpdaterFactory.getGPSUpdater();            gps.getGPSData(row, GPSUpdater.CHECK_IN);
  

  Replication App: (cut a lot of independent code)

  class ReplicationManagerImpl implements LocationListener{    private GPSUpdater mGPSUpdater;
  
      ReplicationManagerImpl()    {        mGPSUpdater = GPSUpdaterFactory.getGPSUpdater();        mGPSUpdater.setListener(this);    }
  
      public void locationUpdated(LocationProvider provider, Location location)    {        mGPSUpdater.newLocationReceived(location);    }
  
      public void providerStateChanged(LocationProvider provider, int newState)    {        //Not worried about this    }}

  Any suggestions are greatly appreciated.

  Thank you

  Notice that the menu close item also called System.exit.

  In this case the application would stop receiving updates following the call of output.  To work around this problem, you can call Application.requestBackground.  This moves the application in the background, where it can continue to operate.  Once you have your final fix application can call System.exit to close itself.

• Static Singleton instance reference gets cleaned memory!

  OK, it's one of the strangest things I've ever seen.

  I am currently working on a project where I use a singleton like this:

  public class SingletonExample {  private static SingletonExample instance; private Vector listeners; private PhoneListener phoneListener;
  
    private SingletonExample(){       listeners = new Vector();     phoneListener = new PhoneListenerImpl();  }
  
    public static synchronized SingletonExample getInstance(){        if(instance == null){         instance = new SingletonExample();        }     return instance;  }
  
    public synchronized void addListener(SomeListener listener){      if(listener != null){         synchronized(listeners){              listeners.addElement(listener);               if(listeners.size() == 1){                    Phone.addPhoneListener(phoneListener);                }         }                 } }
  
    public synchronized void removeListener(SomeListener listener){       if(listener != null){         synchronized(listeners){              if(listeners.contains(listener)){                 listeners.removeElement(listener);                }                 if(listeners.isEmpty()){                  Phone.removePhoneListener(phoneListener);             }         }                 } }
  
    private void reportListeners(){       synchronized(listeners){          int sz = listeners.size();            for(int i = 0; i < sz; i++){               final SomeListener sl = (SomeListener) listeners.elementAt(i);                new Thread(){                 public void run(){                        sl.onListenerReported();                  }             }.start();            }     } }
  
    private class PhoneListenerImpl implements PhoneListener {        public void callAdded(int arg0) {}
  
        public void callAnswered(int arg0) {}
  
         public void callConferenceCallEstablished(int arg0) {}
  
        public void callConnected(int arg0) {     }
  
         public void callDirectConnectConnected(int arg0) {}
  
       public void callDirectConnectDisconnected(int arg0) {}
  
        public void callDisconnected(int arg0) {          reportListeners();            }
  
         public void callEndedByUser(int arg0) {           reportListeners();                }
  
         public void callFailed(int arg0, int arg1) {          reportListeners();                    }

        public void conferenceCallDisconnected(int callId) {} }}
  

  (Not the best singleton, but very safe and is the one I usually use).

  Want to-be-singleton class contains a collection of the listener (I have not included SomeListener interface, but it is very simple, only an onListenerReported of the method). Also contains an instance of PhoneListener. When a call is disconnected, the class of SingletonExample should report each listener on a new Thread.

  Now the collections on static variables is subject to leaks memory, but this class is intended to contain only one or two listeners at a time, so there is not much. And as we are about to see, the static integer variable 'instance' is going to be garbage collected between "consecutive" calls to getInstance.

  Now, I have a method like this, taken from a menu action:

  public void someMethodFiredFromMenu() {  new Thread(){     public void run(){
  
            SomeListener listener = new SomeListener(){               public void onListenerReported() {                    System.out.println(">>>>>>> Call disconnected!");
  
                    //FIXME: Singleton static member is null at this point,                   // so it is constructed again!!!                  SingletonExample.getInstance().removeListener(this);
  
                    //Do other things here                                    }                                     };
  
            //First call to getInstance, static member is constructed as expected         SingletonExample.getInstance().addListener(listener);     } }.start();}
  

  If test you it on a 4.7 Simulator I (BlackBerry 9530 Simulator, v4.7.0.75) you can see that the static variable singleton (named 'instance' within class SingletonExample) is collected between calls to someMethodFiredFromMenu.

  It never happened to me before. Somehow, that there are two threads involved, the JAVA virtual machine (if we can call it ) determines that the variable is more accessible and collects, thus screwing my design.

  Interesting things:

  Make two consecutive getInstance calls in the same thread works.

  Holding a last reference to the SingletonExample within the method of the menu and its use (even in different threads) also works.

  * Note: I've changed a few names from my original code, so there are compilation errors, but at least you know what the code meant.

  It is a feature of the BlackBerry JVM and what others have stumbled on before, including me.

  The best way to summarize the problem is that a static is only a Singleton when the static object references are in the same instance of the Application.

  Another way to say it is that each instance of the Application has its own set of static variables.

  The problem here is that you code earphone is running an application, which will have a set of difference of static variables for your Application.

  Here the best way to create a Singleton in a BlackBerry

  http://supportforums.BlackBerry.com/T5/Java-development/create-a-singleton-using-the-RuntimeStore/TA...

  That said, I would recommend that you avoid treatment on the earpiece - if you can only use global event to convey the information for your Application, then it can be handled in your Application and static object is a Singleton!

  A bit off-topic and just because I'm here, but what's the point of the Thread in this treatment?

  public void someMethodFiredFromMenu() {}
  New Thread() {}
  public void run() {}

  SomeListener listener = new SomeListener() {}
  public void onListenerReported() {}
  System.out.println ("> call disconnected!");

  FIXME: Singleton static member is NULL at this point,
  Thus, it is built again!
  SingletonExample.getInstance () .removeListener (this);
  Do other things here
  }
  };

  First call to getInstance static member is built as planned
  SingletonExample.getInstance () .addListener (listener);
  }
  }. start();
  }

• SMS for outgoing SMS listener throws IOException immediately after the open call

  I had already created a class for sending SMS messages which worked perfectly until I added the listener. When the listener is added as soon as I start the thread throws an IOException exception who am I hurting? The only thing I can think is some kind of wire problem, please help.

  Here's the SMS & Listener class:

  private static final class SmsMessage    {        private String _address;        private String _msg;

• How to remove an item that has been added from code?

  Hello

  I have a BorderContainer component personalized with 2 tags and 1 image.

  I added an instance of it to my code with addElement() request and now I can't make go away

  I am trying:

  for (var i: int = 0; i < numElements; i ++) {}

  If (getElementAt (i) map) {}

  If ((getElementAt (i) as Card).name.substr (0.6) == "cMover") {}

  removeElementAt (i);

  }

  }

  }

  He finds it because it happens to removeElementAt (i); but the component remains visible.

  I also tried removeElement (getElementAt (i)); no luck.

  What I am doing wrong?

  Thank you

  Gabor

  You may need to call

  invalidateDisplayList();

  After that you remove.

• How not to sort datagrid column on double click

  Hello

  I'm currently building an application containing a DataGrid for the representation of data. I created a datagridheader custom in order to add an input text for the filtering of the columns (see code below).

  My goal is to hide the textinput and then display it on a double click on the header. So I would like to know how to avoid the type of this column whenever I double click. ?

  You can use 'alt' or 'Ctrl' click and just check on the event to see if one of these is 'true '.

• AbstractTreeModel

  I was told once in fishing forums it's a bad habit to call #. updateUI() #. revalidate() using abstractTableModel.
  
  I pulled treemodelevents however the JTree object does not seem to respond to these events without back updateUI and revalidate? Why is this?

  After a bit more research, it does not work because JTree does not implement TreeModelListener. That's why you add manually the listener IE

  This is not correct. JTree use an inner class as TreeModelListener and it works correctly for any model of tree.

  The problem is that you do not send the correct events:
  -to insert, you create a node changed event but calls the inserted node. Also the source would be better than the model of the tree.
  -to remove them, do you the same (which will obviously not work). Also it will fail with an IndexOutOfBoundsException if you delete the last one.

  I suggest you read the Javadoc for TreeModelEvent, especially the various manufacturers.

• Spark is the substitution of the MX tab order... Probably something simple.

  Hello

  I have a large project with some legacy code that uses so a hodgepodge of spark and mx components.

  It's very well for the most part, they work side by side with only a few small problems as to remember the difference between removeChild and Microsoft.SqlServer.Management.Sdk.Sfc.ISfcCollection.RemoveElement etc..

  BUT...

  I have a complex, dynamically generated form that I should be able to tab between fields of integrated mx and time subject than I tab, no matter what I do, need me _OUT_ of the generated complex shape and plonks me in the first spark control there - usually the home button at the top left.

  This, I hasten to add, is really not a good user experience!

  I tried all the obvious things (tab activation, tab, etc.) but the spark just seems to replace everything, like say "why this dirty _old_ mx component would focus? he don't know even what to do with it? »

  So, please, does anyone have helpful advice on the integration of the mx components in the hierarchy of the development of tab?

  Thank you

• Leak memory causing module DataGrid column

  Hi all

  I have problems with a column of the DataGrid preventing a module to be communicated properly. I can't imagine that this is the intended behavior.

  Using this simple test case, a WindowedApplication and a mx:Module I wonder if anyone can reproduce this problem. The problem disappears if you simply comment the GridColumn Instance.

  Can anyone offer advice?

  Thank you very much

  James

• Exception of null focusManager scroller

  Are currently working on a project that needs to take one component & pop out of it is parent of the top-level application. I use a spark textAera. Initially when the textArea component is "not broken out on" the textAera works very well. However, when it is popped and a user focused then in on the text box a null object reference are thrown by the method of class focusInHandler Scroller.

  To remove and eject the component code that I use is currently:

  IVisualElementContainer (resizeComponent.parent) .removeElement (resizeComponent);

  FlexGlobals.topLevelApplication.systemManager.addChild (resizeComponent);

  where resizeComponent is the component wants to get out.

  Exception occurs when we focus, in Scroller.as:

  override the focusInHandler(event:FocusEvent):void function

  {

  super.focusInHandler (event);

  When get us the focus, make sure that the item is visible

  If (viewport & & ensureElementIsVisibleForSoftKeyboard)

  {

  var elt:IVisualElement = focusManager.getFocus (as IVisualElement); object null exception thrown here

  lastFocusedElement = elt;

  }

  }

  What I am doing wrong?

  Thank you

  Kevin

  Kevin,

  The problem is that your popup does not implement the IFocusManagerContainer interface.

  The IFocusManagerContainer implementation allows the system to assign a focus Manager to the pop-up, and this error disappears.

  Kind regards
