How to handle complex properties after creating components?

If I create a new object of a ComponentDefinition, I pass a variable as a property to it.

page var = serviceDetailsPage.createObject ();

page.service = servicesDataModel.data (row);

NAV.push (page);

The content of "page.service" is an object and I need to extract data to display on the newly created page.

{Label

text: service ['name']

}

This simple example works fine, but I need to do something more "complex". I tried to use onCreationCompleted, but the event is fired to early because it is trigged until the property is assigned.

onCreationCompleted: {}

Service ["components"] .forEach (function () {}

// ...

});

}

I'm looking for another event that is emitted when the page is displayed to the user (or before!) for access to the property and use that he is happy for the manipulation of the Fryer.

Try this:

var component = Qt.createComponent("MyPage.qml");
var myPage = component.createObject(nav, {
    "service": servicesDataModel.data(indexPath)
});
nav.push(myPage);

  • How to handle the onTriggered many ActionItem created dynamically

    Hi, I created the ActionItem dynamically using (loop)

    because data is from webservice

    How to handle the onTrigerred?

    If my code is like this:

    for (int i = 0; i)< alist.count();="">

    {

    My page page * = iRoot-->findChild ("SpecificObject");
    ActionItem * action = ActionItem::create () .title (aList [i] .name);

    bool res = QObject::connect (action, SIGNAL (triggered ()), this, SLOT (handleAction (())); what I'm confused because I don't know what action is triggered
    Q_ASSERT (res);
    Q_UNUSED (res);

    my page-> addAction (action, ActionBarPlacement:efault);

    }

    MyClass::handleAction() Sub

    {

    aFunction(); This parameter of function required of aList, said user.user aList [i]

    }

    Do I need to create handleAction() as well as added actionItem SLOT

    But I don't know how much action added because it is dynamic server

    Thank you

    There are a few options:

    Create a single location and connect all the signals. You can then call sender() into the slot to retrieve the object that sent the signal and go from there. You can also use a QSignalMap that maps each signal to a value and send this value to a single location. You can also use QSignalMap::sender() to get the sender object.

    I used the QSignalMap to do something similar for handling created dynamically successfully drop-down lists.

  • Create components in a loop and how to reference them

    Hi all

    I have a problem I know not many have met before, but I am a little confused (maybe it's too early )

    I want to do two things:

    1. I want to run a loop of creating components

    for example

    Pseudo code

    for (i = 0; i < 10, i ++)

    {

    create a new button called here "Warning" (will get ten buttons called Button0, Button1... Button9)

    }

    2. I want to then be able to refer to them without knowing their names at compile time

    Pseudo code

    for (i = 0; i < 10, i ++)

    {

    Key [i] .width = 100;

    }

    How can I do this please?

    See you soon

    Ian

    Declare a buttonArray, and push them in the table that each button is created.

    for (i = 0; i<10,>

    {

    create a new button called here "Warning" (will get ten buttons called Button0, Button1... Button9)

    var btn:Button = new Button();

    buttonArray.push (btn);

    .

    .

    }

    while making reference to

    for (i = 0; i

    {

    (buttonArray [i] as button) .width = 100;

  • How to set the properties of the EOS in the IVI driver

    I am coding a compatible driver IVI (in LabWindows/CVI) for an old GPIB instrument that does not support the EOI. To read the response device, I need to define the character of the EOS and terminate read on EOS. MAX I can correctly set the properties of communication and communicate with the device, but I do not know how to set these values in my driver. I tried if various attributes (for example with viSetAttribute (io, VI_ATTR_TERMCHAR_EN, VI_TRUE)), but still get errors (I guess I should use the incorrect session handles). How to set these properties inside the device IVI driver properly? These parameters must be active for this specific device only - all other devices on the bus use EDI. So I think that I can not just in the world, set this property on the map.

    Any help is appreciated. Thanks in advance,

    Martin

    To change VISA attributes as parameters EOS via the pilot of the IVI, your application must first acquire the handle valid VISA (VISA session) or the IVisaSession interface. The first is applied when the uses of pilot IVI VISA - C API and the latest is applied to when the IVI driver uses VISA COM API. Session handle of the IVI - C (that was returned by the function _init() ) is * NO * a VISA manage so you cannot call the API C VISA with the session handle.

    I don't know if the IVI driver you are using has such a property or attribute allowing to access the handle VISA or IVisaSession interface, but for example, driver Agilent IVI COM "IO" property, which returns the reference to IVisaSession or any good VISA com interface.

  • Windows 8.1 did not create a user profile after creating a new user

    I was deeply puzzled by this problem.

    Just bought a MS Surface Pro 128 GB and upgraded to 8.1 Windows it works fine until I needed to create a new user. He is a user of child for my daughter with a local account only. After creating the new user account, I tried to logon. He complained "user profile Service does not have the sign in» Google it and found the solution to change the registry for the location of the profile displayed on many sites. So I launched regedit. But to my surprise, there is no entry for the new user to the profilelist title - there are only two entries: one for me (admin), and the other is for a user named "fwuser". So I couldn't use the method to rename the master for this problem.

    Could someone give me a tip, which could cause this problem and how to fix it? Much appreciate it.

  • [MAF - AMPA] How the custom/override error after the failure of the asynchronous Web service call?

    Hi Experts,

    I am looking for a best practice to make the error handling in the MAF.

    Currently my application is using AMPA and call the REST service.

    However, I would like to know how to handle this kind of error

    1. the device is not connected to the network (can we personalized it?)

    error2.png

    2. the device is connected to the network but cannot call service

    error1.png

    3 and the other exceptions of the asynchronous call to the AMPA

    In addition, how to mark a method call in the exception handler?

    referring to this http://multikoop.blogspot.com/2014/02/adf-handling-exceptions-from_14.html in ADF tf we mark as exception handler.

    Best regards

    Hendry

    Hendry,

    You have several options. It depends on how you want to handle exceptions:

    -If you just want to hide the mistakes of web service end-user call, you can set the showWebServiceInvocationErrors property in the persistence - mapping.xml to false (you want to generally this set to false, by putting your application in production, the default value is true, because during development, it is more convenient to directly see the errors of appeal WS)

    -If you want to display a custom error message, you can create a subclass of RestJSONPersistenceManager, register for this subclass using the property "remotePersistenceManager" in persistence - mapping.xml and override the handleInvokeRestServiceError method.

    It depends also how you want to process POST/PUT/DELETE requests that fail. Do you want the AMPA runtime register this request as pending for the runtime synchronization action automatically tries to return the claim later? Or you just want to display an error message to the end-user with a text like "try again later?

  • How to recover a database after you add a data since the last file backup.

    How to recover a database after you add a data file to a tablspace existing since the last user managed backup.

    PS: I am aware that the user managed backups are not used and RMAN is used these days.

    At the stage of the mount: select name from v$ datafile;
    The last entry indicates a file named /xxx/xxx/.../UNNAMEDXXX.dbf

    Now

    ALTER database create datafile ' / xxx/xxx/.../UNNAMEDXXX.dbf' as 'path_where_you_want_to_add_the_datafile ';

    The name of the data file must match the name that added in production

    This will create a data file to the required location.

    Once the file has been created, you can continue with recovery.

  • How to code complex conditions

    Hello world

    First of all, please forgive if I don't use the programming terminology correctly, I'm a beginner with no computer training.

    My question is a general: what is the right approach for complicated code conditions?

    I start with a good example that is actually something concrete I should do in my little application:

    TODO: shorten/shorten a complete person by name to fit a character 16
    For example: Johnathan-> J necromancer necromancer

    There are many possibilities how to make based on the length of the first, model and other names and there is an order of preference for these solutions.
    So if possible shorten only the name as above; If it is too long and then leave some space and so on. These would be the preferences demonstrated by examples:
    1 J L Smith
    2 JL Smith
    3 JLSmith
    4 John Languely S
    5 John Lang B S
    6 John L S
    7 JohnLS
    8 J L S
    9 JLS

    How to encode? With the nested If if if-else blocks or in some other way?

    First of all I did with the nested If - s, but it was sort of a mess after some time, so the easiest way for me was to do the following:
    (Just 'calculate' names abbreviated in order of preference, and return if it fits in the 16 characters.)
    if (displayName.length() > 16) {
    
                   String[] dn = displayName.split("\\s+");
                   String lName = dn[dn.length - 1];
                   StringBuffer dName16 = new StringBuffer();
                   
                   // J L Smith
                   dName16 = new StringBuffer();
                   for (int i = 0; i < dn.length - 1; i++) {
                        dName16.append(dn.charAt(0) + " ");
                   }
                   dName16.append(lName);
                   if (dName16.length() <= 16){
                        return new String(dName16);
                   }
                   
                   // JL Smith
                   dName16 = new StringBuffer();
                   for (int i = 0; i < dn.length - 1; i++) {
                        dName16.append(dn[i].charAt(0));
                   }
                   dName16.append(" " + lName);
                   if (dName16.length() <= 16){
                        return new String(dName16);
                   }
                   
                   // JLSmith
                   dName16 = new StringBuffer();
                   for (int i = 0; i < dn.length - 1; i++) {
                        dName16.append(dn[i].charAt(0));
                   }
                   dName16.append(lName);
                   if (dName16.length() <= 16){
                        return new String(dName16);
                   }

    //more code..
                   
    I would like to know how to approach these kind of situations effectively and clearly in the least error prone way. How to code complex conditions? Is there any book or theory about it?
    I am not sure it is clear what I am asking, but I will follow up with more description on what I mean later. But please comment, ask, advice anything in the meantime - I would really appreciate any help with this.

    Hello lemonboston,

    If you compare that with my proposal there are only a few more steps to get there.
    The iteration on your list looks almost exactly like mine...

    Right now, your convertDisplayNameToFitIn method has two responsibilities: building the list and selecting the abbreviation. You will have to hunt in the methods that they own.

    Beside that, you need to declare types interface references where possible. I got this abbreviatedList thing should be reported as list rather than ArrayList:

    List abbreviatedList = new ArrayList();
