remove objects and events

Hello

If I do a removeChild on a button, did remove the EventListener or what I have to do this first?

Harry

Hey Harry,.

According to the ASDocs:

http://www.Adobe.com/LiveDocs/Flash/9.0/ActionScriptLangRefV3/Flash/display/DisplayObjectContainer.h...

just by using the removeChild() function child objects parent null and property "dissociates" he of the parent object by assigning the value null. If the object is still floating around just, without a parent object and therefore eligible for garbage collection. However, if there is an eventlistener on the abducted child I don't think only one active garbage collected because there is always a reference to this object even if it is not visible. I think that it is confirmed by this line of the doc:


«.. . the object is garbage collected if no other references to the child exist. »

its always good practice however, to have your own function dispose() on a class that removes all listeners and sets the object to null. garbage collection in actionscript is not flawless, so I think they recommend that you reuse objects rather than try to remove them and to create later.

  • [Noob questions] Model oriented programming OBJECT and event Flex

    Hello, I have two very easy questions for an expert - I think.

    (1) issue-oriented object

    If I have a

    UserElement extends the Image

    UserImage extends UserElement

    UserText extends UserElement

    ...

    UserSomething extends UserElement

    Each UserSomething derived from UserElement has an editElement method that can be placed in the superclass UserElement needs to look exactly because in this journal.

    Now, from the root of the Application, I have to call the editElement, but I'd rather not be forced to have a giant switch inelegant structure... There is a way to dynamically cast to the right class?

    (2) issue of event model

    I read the documentation and googled around, but if I have this structure

    Application

    Canvas1

    Control1

    Canvas2

    CONTROL2

    and I send Control1 event, the full path is Application > Canvas1 > Control1 > Canvas1 > Application. But if I need control2 to know that this event is FAILED, the only way I see is to call a method in the Application control2. Is this correct or there is a way to redirect the event in a way to broadcast?

    Thanks in advance for anyone who wants to answer

    maestro91,

    Answer, no, protected Alexander is very good and I used it in this way - protected is visible to inherited classes OK.

    You should be able to:

    var r: derivedClass;

    a = new derivedClass();

    function do_something (b: baseClass)

    {

    test to find out which class that I was adopted, then derived

    ((derivedClass) b) .editelement ();

    above must call the correct method

    }

    You must explicitly cast to ensure the right call gets shot, but you used baseClass as an argument, so you can send your derived through classes.

  • How to remove the alarms and events database of Citadel?

    Hello

    I use LV 2010 with DSC.

    I made a mistake in my program and I wrote too much data event and alarm at the Citadel. Database *.mdf/*.ldf files are quite large > 1 G. Normally, I connect only two alarms per day. I want to delete all events alarm + data before a certain time of stamps for example. 1.1.2011. How can I do? I tried to use MAX and perform the operation so I wrote small program which reach the data from temporary database and then remove it. Yet I can find old events and alarms... I am able to remove the traces of old but not the events/alarms. How do I remove the alarms and events?

  • Job queue and event ADVANCE.

    Hello

    I'm getting to do advanced queues work which could be removed by the use of event in function. For a single message, it seems to work but if I queue of messages more some of them are 'lost' without having been processed. In below code I create job scheduler queue and event. Then I enqueue messages 3 - two immediately after each other and third with 5 delay. Only the first and the third message are processed (and written to the TST_DATA table). In the queue table, it seems all messaged have been processed. RDBMS version is 12.1.0.2.

    SELECT * FROM TST_DATA;
    

    Hello

    you're right: after two immediate queue operations and a separate queue there are only two lines in the table

    (tested on 11.2.0.4):

    SQL> select * from tst_data;
    
    SCOMMAND
    --------------------------------------------------
    test1
    test3
    

    If you wait just 1 sec after each DBMS_ENQUEUE there are 3 rows.

    Even with a visibility using DBMS_AQ.COMMIT and COMMIT after that each line there are only 2 rows.

    This mechanism using DBMS_SCHEDULER and EVENT_MESSAGE functionality seems to be a bit slow.

    You must specify the option parallel instance for your business:

    DBMS_SCHEDULER.set_attribute ('TST_JOB', 'parallel_instances', TRUE);
    

    You will get then 3 rows, even without a delay of sleep:

    SQL> select * from tst_data;
    
    SCOMMAND
    -----------------------------
    test1
    test2
    test3

  • Add/Remove objects of the 3D scene programatically (or show/hide)

    I have a project I'm working on where we need to somehow add/remove objects in a 3D scene but without major lag.  Basically I have a set of objects in the real world I am reproducing in a 3D scene by loading 6 STL files.  I want to display only one of these items at a time.  When the currently displayed object is no longer present I want to quickly view another.

    I tried the subject 'remove' invoke the node without success.  I also tried a few other techniques that people have posted deal with transparency, but without a bit of luck.  It seems to me to recreate the scene when objects change is not an appropriate solution, because it seems to be a long process.

    I was wondering if there is someone who has done this or something similar in Labview.

    -Thad Briese

    These links are for images.  Not for 3D objects.  I had this work with the Object.Remove method.  The main thing to keep in mind is to know what items are currently displayed in places and do not attempt to apply transformations, etc to objects that have been deleted.

  • Problem when I add any object and camera

    Hi all, thanks for helping me with this.


    Here is a link to a video I recorded showing my problem.

    77c8e8bd-51e4 - 42d 7 - 97 d 8 - b918f7d12f84.3gp - Google Drive

    After you run the 3D Tracker and the creation of any object and camera.  The angle of the camera moves as the original video moves as well.  I want the camera to stay still instead of tilt angle of the video.

    Thank you

    Aaron

    Your screenshot is Aussie bad quality that I can't really tell exactly what you're doing, but looks like you're not understanding what the tracker of the camera is, or how it works. First of all, the video layer must be 2D. You have changed the video layer 3D and it would never work. Tracker camera recreates a camera inside the AE that corresponds to circulation, the focal length and the position of the camera to film the scene. Camera Tracker provides a way for you to create a ground plan and original that align to a starting point in 3D space of AE so the global center of the model is aligned with a geometry in the plan. Camera Tracker of the AE does not match lens distortion, so if you keep track of the shooting was shot with a lens wide angle and there is a lot of distortion so you must remove this distortion before follow-up or the edges of your 3D objects will drift as the camera moves unless they are located in the center of the photo that is free from distortion.

    I don't know what you're trying to accomplish with your shot. Looks like you followed the middle section of the video and the fact that the 3D layer. It would never work. The normal procedure would be to add a camera and a null value or a solid or a text composition. Then the 3D layers will be stick to shooting perfectly if there is no significant lens distortion.

    Please explain in detail exactly what you're trying to do and if you don't ccreencaptures put it on YouTube using full HD will give us something we can see better. It would have helped if there was audio on your video explaining what you were trying to do.

    Please enter Tracker camera find help in the upper right of the AE and study up on the functioning of the tool.

  • remove objects from the background using a clipping path

    A number of years, I've learned a very easy way to remove objects such as logos from backgrounds using masks and then saving them as .eps files that might be included in the InDesign documents without funds. You would simply use the magic wand to make a selection, inverse, create a path and the rest I do not remember.

    Simply, I can't find the notes I had on how to do it and can't remember the steps. It would literally take 2-3 minutes at the most to do.

    Does anyone know of this method, or something similar and very simple. At best, I am a Photoshop basic user.

    SRiegel wrote:

    You don't need to (and probably shouldn't) eps more use.  This is an obsolete format.

    The clipping path will read as well in a PSD or a TIF.

    You can also use any Photoshop path recorded as a trace of shadow in InDesign, even if it has not been identified as one in Photoshop.  Object > Clipping Path > Options allows you to choose a Photoshop path in the file.

    At took the words out of my mouth.  PSD is the preferred format for most applications these days.  You can choose to import as a single merged object or keep the layers.  EPS works well with Photoshop.

    In response to Sid, if you use a clipping path to draw a logo, then you might as well make the logo as a vector of the form of the original using as a model.  I regularly take this approach fuelled the logos of low resolution for things like sponsors etc.  Because you do not use the raster version, you can n to facilitate tracking it.  All the perpendicular lines of the limits of the image (don't know why I don't have not just "square") can be stored neatly by use of Guides, but you can also force the path points to have a square to the previous point by holding down the SHIFT key.  The resulting vector shapes can be saved as custom shapes, but I use libraries as you can organize them better.

  • Retrieve the tasks and events for a Virtual Machine

    Hello everyone.

    This question may seem trivial to some people here, but I cannot make it work: I would like to use VCO to retrieve the tasks and events for a specific virtual machine (IN parameter). Can someone help me to do?

    Best regards

    As I said, it must create a collector by using the createCollectorForTasks method in VcTaskManager.

    The parameter of this method is an instance of VcTaskFilterSpec, in which specify you the object to filter (in your case, the reference entity VM)

    You will get a VcTaskHistoryCollector which can only be traversed by using the methods readNextTasks and readPreviousTasks.

    // Get TaskManager service
    var sdktm = vm.sdkConnection.taskManager;
    
    // Create FilterSpec containing vm reference to filter
    var filter = new VcTaskFilterSpec();
    var spec = new VcTaskFilterSpecByEntity();
    spec.entity = vm.reference;
    spec.recursion = VcTaskFilterSpecRecursionOption.self;
    filter.entity = spec;
    
    // Create collector
    var collector = sdktm.createCollectorForTasks(filter);
    collector.resetCollector();
    
    // Browse all pages returned by collector (10 entries per page)
    var taskPage;
    while ((taskPage = collector.readPreviousTasks(10)) != null)
    {
        for each (var task in taskPage)
        {
            System.log("Task: " + task.name + " -> " + task.startTime);
        }
    }
    
  • Duplicate an object and create it move on the stage

    Hello

    I'm having a problem in actionscript 3.0 game development. The game plan is to have planes flying across the screen and the player must shoot by clicking on it. As the player gets more points, it must be of planes flying across the screen. No matter what I try, I can't work. Can anyone offer any coding suggestoins for coding in general and him duplicate the object and spawning it out side of the scene.

    Create the plan as a library item and assign a class name (for example you name Plane).  To create a new instance of it you just use...

    var another_plane:PLane = new Plane();

    addChild (another_plane);

    planes.push (another_plane);

    The last line place the plane newly created in a table that you set above all create so that you have a way to target the various plans which, added to the process (moving, etc) them.  When one of them is no longer at stake, you can remove the table so that it gets not be processed.

    Hey,.

    Recently encountered a problem where someone has configured a vCenter server to use a MS SQL express 2005 database, and the DB hit the size limit of 4 GB for vCenter wouldn't start. In order to make things to start working again, I deleted some data old tasks and events in the tables VPX_EVENT, VPX_TASK and VPX_EVENT_ARG. However, I prefer not to have to do it and to wait for a problem like this from happening again. I know that you can set the time of retetnion records statistics and perf, but you can do the same for the event data and the task? After removing the records I had more than 3 GB of free space in the database.

    Any advice much appreciated

    Unfortunately in the vCenter 2.5 line, there is no automatic size.  In vCenter 4.0 (once it is out), there is a retention settings task and events you can follow events for x amount of time.

    What kind of events seem to be completing the tables?

    Is this pubsub adapter an adapter http-pub? Then you need your event beans implement StreamSource. Here is an example of code for this:

    / public class SimpleEventBean implements StreamSink, StreamSource {}
    private StreamSender sender;

    {} public void setEventSender (s StreamSender)
    sender s =
    }

    public void onInsertEvent (Object e) {}
    If (sender! = null) {}
    sender.sendInsertEvent (e)
    }

    }

    }

    In addition, you must define the event as bean rather than . and add the adapter http-pub as it is listener.
