Change the scope of the qml created object

My main QML, I call another qml using

 attachedObjects: [
    ComponentDefinition {
        id: splash
         source: "splash.qml"
     }
]

I create the splash to help screen

var splashSheet = splash.createObject();
splashSheet.open();

Now I want to change a label on this object.

I exposed the label using an alias of the property.

As long as the variable is in scope, I can use

splashSheet.stateLabel.text = "new text"

How can I do this in another function where I can't access the var splashSheet without creating a new object?

One option is just to set a property of type variant in your component root (or any other place the two pieces that can access), store a reference to the object is. That is, "mySplash variant property" and when you create, retain a reference with "mySplash = splashSheet", and then later to use 'mySplash.stateLabel.text' to achieve this.

  • How to change the type of object?

    I have an object type, as shown below:

    Here are the object and its type

    create or replace type test_object1 as an object
    (
    val1 varchar2 (50).
    val2 varchar2 (50).
    VARCHAR2 (50) val3
    );

    create or replace type test_type1 is table of the test_object1;


    Now I want to change the type of object. I want to increase the size of val1 to varchar2 (100).

    Any body could help for the alter script.

    You cannot change the underlying type unless you use the CASCADe or INVALIDATE option.

    Specify the CASCADE clause if you want to propagate the type change to the tables and dependent types. Oracle database abandons the statement if errors are found in the dependent types or tables, unless you also specify the FORCE.

    If you change the property of the type between FINAL and NON-FINAL, you must specify this clause to convert data in the tables and dependent columns. Please refer to [NOT] FINAL.

  • Please help: cannot change the order of objects on the stage by dragging in the timeline

    Hi all, I am using Captivate 5.5 and try to change the order of objects on my stage.

    I searched on the internet and read the FAQ here. I cleaned my cache of projects. My slide number amounts to 61, so not very big.

    I wonder if it is because I have several interactive objects, on the other?

    For all the blocks on this stage, with the exception of the one on the left of the first line, I have a picture of grayout, a slidelet, a click box and a real picture, all stacked together. I need to order them correctly so that they play in the right way. I have the right order for the second block on the first line, but can not change the order for the rest of the objects by dragging in the timeline - it just won't let me hang out.

    Here is the screenshot of my scene and a part of the timeline. Thanks for the tips!

    It turns out that I made a stupid mistake by dragging the names of objects instead of the real thing... Sorry guys.

  • Exponent of the QML C++ objects

    Hello

    I am new to qml and BlackBerry. What I want to do is basically described in this link:

    http://developer.BlackBerry.com/native/documentation/Cascades/dev/integrating_cpp_qml/index.html#exp...

    under "C++ objects exposing to QML.

    I did everything as described in the link. The point where I'm stuck is how to get out of here

    MyCppClass *cppObject = new MyCppClass();
    qml->setContextProperty("cppObject", cppObject);
    

    here

    Label {
      text: "Value of cppObject: " +  cppObject.value
    }
    

    When I know the code I need to create an instance of my class in the main.cpp file [MyCppClass * cppObject = new MyCppClass();] then setContextProperty to make it able to expose values to qml [qml-> setContextProperty ("cppObject", cppObject)]; and I can get the value by writing "cppObject.value" in my qml file.

    However, I get this result in the Console:

    ReferenceError: Can't find variable: cppObject

    I need to add something in the qml code so that the functions defined in C++ can be used in qml?

    I hope that these are enough information to help me here.

    All understood why I got this error.

    After you have created an instance of the class

    TMinutesContact *MinutesContact = new TMinutesContact();
    qml->setContextProperty("MinutesContact", MinutesContact);
    

    I need to set up

    AbstractPane *root = qml->createRootObject();
    
    app->setScene(root);
    

    to fill the contacts added with my duties of the class 'MinutesContact '.

    I don't know yet what exactly setScene does so that it now works.

    The App I'm trying is essentially over. The only thing missing was to implement you can get data of the qml code C++ objects. I am familiar with C++, but qml is new to me. So first of all, I had to struggle with all this code in this app.

    For all postal code containing in this app would be too much. And I don't know if I'm already good enough to choose just the necessary part that is important for my problem.

  • Read the dynamically created objects

    Hello

    I get my feet wet with development of Cascades, and I was hoping someone here could answer some questions I had.

    I am defining a container that contains a drop-down list and a zone of textfield and I need to repeat this containing three more times. I thought by using the ControlDelegate class to create three instances without writing the code three times. However, I don't know how I'd read the value of each instance of the drop-down list and the ControlDelegate textfield.

    Any Suggestions?

    If you instantiate the like this:

    Container {
        property variant control1
        property variant control2
        property variant control3
    
        id: rootContainer
        Label  {
            text: "Example Component Definition"
        }
        Button  {
            text: "Click to create dynamic component"
            onClicked :  {
                // Create the component and add it to the Container
                control1 = compDef.createObject();
                rootContainer.add(control1);
                control2 = compDef.createObject();
                rootContainer.add(control2);
                control3 = compDef.createObject();
                rootContainer.add(control3);
            }
        }
        attachedObjects: [
            ComponentDefinition {
                id: compDef
                textfield { id: text }
            }
        ]
    }
    

    Then components are accessible as control1.text, control2.text etc.

    If the number of objects is constant, then ControlDelegate might be more convenient.

    For ListView, you can use ArrayDataModel or GroupDataModel (for more complex models with sorting) and fill it with any type of data. Any kind of items can be added, it's just a picture of QVariantMaps. It is not necessarily Xml or SQL wrapper, but specialized models also exist for this. It is even possible to create a subclass of DataModel custom c++ to expose existing data objects.

  • Changing the once created package.ini

    Hello

    Bit of a noob question, but is it possible to change the file package.ini once the application is passed through the ThinApp process? Or the application needs to be re-ThinApped? Add some entry points to our ThinApped versions of the runtime Java and Adobe Reader, we have Internet Explorer installed locally on desktop computers and is not grateful Java Runtime or Adobe Reader. As Internet Explorer is local to the office, I assumed that ports of entry within these applications should be created for it, please let me know if this is not correct, problems with any Web site with applets Java etc. or wanting to the Adobe Reader plugin.

    Thanks for any help in advance.

    Kind regards

    Ross

    After you create an entry point for IE, you should have an iexplore.exe file in your file Thinapps containing the Acrobat Reader software.

    If you start IE using this file (double click in Solution Explorer) iexplore.exe, it should start IE in the virtual bubble of Acrobat Reader a plugin should work. For the first test, close all other IE Windows open, maybe IE is smart enough to recognize that another instance is open and he uses this instance, instead of creating a new.

    Also I tried to install IE as a ThinApp, I don't know how this can be done, but I have capture IE, and when I try to install it on view Admin he comes back as invalid state and will add to the list of the ThinApps. I captured it by just clicking the button of Internet Explorer and choosing "Include a point of entry for the system installed, IE", it is a valid way of ThinApp IE? or we would literally have to uninstall IE and then install again then capture that?

    For EI in a virtual session running, your approach is valid, at least if you use Thinapps on a normal system. I have no knowledge on vmware View, so I can't say anything for your mistake. I used this approach on IE, and it worked on stand-alone computers.

    But for your captured IE to see the Adobe Reader plugin that is contained in another package Thinapp, you must add the package.ini applink enter, so that the newly created only IE package see the contents of the package of Adobe Reader.

  • Script to change the presence of objects based on the range of amount

    Hello

    Is it possible to change a presence of objects (a field or a subtitle), from the amount range entered in a numeric field?

    For example:

    -The amount of entered number field is a range between 1 and 49 999, then "Signature subtitle 1" is displayed.

    -The amount of entered number field is a range between 50,000 and 250 000, then 'Signature subtitle 2' is displayed.

    Etc.

    Any advice for this script would be appreciated.

    Thank you!

    Hello

    Try something like this JavaScript in the event of your field digital output (you probably need to change the name of your objects in shape, SignatureSubhead1 and SignatureSubhead2)

    switch (true)
    {
     case this.rawValue >= 1 && this.rawValue <= 49999:
      SignatureSubhead1.presence = "visible";
      SignatureSubhead2.presence = "hidden";
      break;
     case this.rawValue >= 50000 && this.rawValue <= 250000:
      SignatureSubhead1.presence = "hidden";
      SignatureSubhead2.presence = "visible";
      break;
     default:

  • Laptop HP Pavillion 15-p051u: HP Recovery Manager should be able to change the computer creating media?

    I'm doing the original backup set of DVDs for a laptop HP Pavillion (15-p051us) 15. Due to an error, I'm afraid to continue.
    I got to speak with a HP tech person, who helped me to pass the second record to DVD. now, I'm trying to start the burning of the third DVD of backup recovery. When I click on the button to launch the "HP Media creation" I get interrupted with a window which shows:

    ***********************************************

    I obviously don't want to change the program to backup for me when I'm not finished to make the backup. (As I've noted, two DVD's burned and verified. Four still needed.) But when I click on the button 'No' to say "don't edit my computer now until I finished the last four DVD" disappears from the user account control window and the creation of HP recovery media is not engaged. My first two questions are (1) why my computer wants to interrupt the creation of my 6 DVD recovery until the work is done? (2) it would be safe for me to click on the 'Yes' button or what may cause a fatal error in the backup process? In a note, I would like to report that the person HP with whom I spoke on the phone mentioned the fact that the error can be caused by lower DVD media. To counter this notice I tried three DVD good nine successive State. I used more than a dozen DVDs of this package on another computer. With these, he had no problem with registration, verification or later to read these DVD. If my guess is that it is unlikely three of them failing in the HP computer. I don't think that's the problem. I read through 60 first found elements that were identified when I did a search on the website of HP using the key phrase 'Recovery Manager change'. This has proved a total of 7499 possible Articles, but I looked through 60 without success.

    Answer Yes to user account control. This is the irritating feature of Windows that assume at all times that you don't know what you're doing. HP Recovery is harmless and should have access to the files on hard drive.

    For example, you could get the same question when you try to install the software for a printer, etc. and would answer Yes - you would answer no if a piece of malware slipped on your system and UAC taken he's trying to make changes and pointed out.
