Destroy the definition component qml in c ++ destructor

I install some components, but they can only be destroyed if the application will be closed.  Currently, a mistake is cause attesting that they are not made when the application is closed.

What I am unsure of is how to reference the alias or objectname to a definition of compoenent in c ++ and then destroy it.

ApplicationUI::~ApplicationUI()
{
  // Destroy the sound manager.
    ComponentDefinition *myDef = bb::cascades::Application::instance()->findChild("myDef");
        qDebug() << "Destroying Definition";
        myDef->destroy();
}

Only, I was not able to find how to link the component definition in c ++ because it doesn't have a #include<>

If not, is there something in qml who inform me just before the application closes, so can I do this?

Normally, you can solve it by setting the parent of all objects you create in your definition. The parent must be something that you know will be destroyed when your application is closed, as the app itself class.

I don't think you should look for ComponentDefintion but because it's just a factory for components, you do not create. You should rather look for the type of object that creates the definition.

Also, do you you know that some objects of Cascades don't clean up after them properly and may generate errors no 'no' even if you do everything right. Why don't post it your console error messages because it can help you get an answer better than this one.

  • destroy the page created with C++

    Hello

    How do I destroy a thrust from a NavigationPane page when the page is created with C++.

    Here is the code:

    // applicationui.cpp
    
    Page* ApplicationUI::doLoadPageDetails(QString fn) {
    
      QmlDocument *qml = QmlDocument::create("asset:///PageDetails/PageDetails.qml").parent(this);
     [...]  Page *newPage = qml->createRootObject();
    
      return newPage;
    }
    

    When I open the app displays a ListView. When I push on one of the elements in the list the PageDetails page is shown.

    // main.qml
    
    [...]onTriggered: {
                        var selectedItem = dataModel.data(indexPath);
    
                        var page = app.doLoadPageDetails(selectedItem.toString());
    
                        navigationPane.push(page);
    }
    

    Now, I have written a delete action in the application.cpp

    void ApplicationUI::popFinished(bb::cascades::Page* page) {
        delete page;
    }
    

    and used in the main.qml in onPopTransitionEnded:

    onPopTransitionEnded: {
            // Destroy the popped Page once the back transition has ended.
            app.popFinished(page);
        }
    

    But it's not destroy the page. Can someone tell me how to get destroyed page when you press the ButtonBack?

    The count method gave me what I expected when I start the application number is 1-> home page.

    When I click on an item on the next page open-> count = 2.

    When I come back-> count = 1.

    But I solved the problem.

    The second page is filled with information from functions in C++. So in my additional popFinished function on page "Delete" now also clear the list of contacts with the clear function, as I said before.

    void ApplicationUI::popFinished(bb::cascades::Page* page) {
        Contacts.Clear();
        delete page;
    }
    
  • Destroy the NavigationPane Page when used of a Peek

    Hello
    It is possible to destroy a page when the rear sweeping gesture (peek) is used to jump to the page of the NavigationPane? I don't want to use the property ' peekEnabled: false "I like the gesture of glance. I can't use the signal to onPopTransitionEnded I don't know the id of the page that will be skipped (using ComponentDefinition).
    The following is a snippet of the code:

    QML File 1:
    NavigationPane {
            id: navPane
        CustomControlPage{
    
            }
    }
    
    CustomControlPage.qml
    Page{
    ...
    
      onTriggered:{
    // I need to create a new Object everytime and that is causing the  problem when peek gesture is used rather than back button as with backButton, I can just use paneProperties and then do pageID.destroy();
    
        var newPage = newCustomPage.createObject();
        newPage.variant1 = "hello,";
        newPage.variant2 = "world!"
        navPane.push(newPage);
      }
      attachedObjects:[
       ComponentDefinition{
        id: newCustomPage
        source: "newCustomPage.qml"
       }
      ]
    }
    
    newCustomPage.qml
    Page {
     id: newPage
     property variant variant1
     property variant variant2
    ...
    
    paneProperties: NavigationPaneProperties{
      ActionItem{
       title: "Back"
       onTriggered {
          newePage.destroy();
       }
     }
    }
    }
    

    Thank you!

    Yes, that's correct. 'page' is a parameter, it points to the page that you need to destroy.

    popTransitionEnded is called when the page is closed using a "back" button or closed using the gesture of glance.

    It cannot be called if you delete the page programmatically, I'm not sure about this.

  • Can not access the context in QML property

    So I have an arraydatamodel in the CPP file, I use qml-> setContextProperty (...) to set it up to allow QML to access, the strangest part is, no matter if I put it in navigationPane Page or a container, it keeps saying can't find not variable, but in the same QML in ListView, they can access it without a problem. The other weird part, it is an another QML is able to access it in the tag of the page, the same model.

  • Director of Windows won't start; How to fix error: "component identity found in manifest does not match the identity of the requested component»

    Whenever I try to start Windows Movie Maker, I get the following error:

    "Sorry, cannot start Windows movie maker. Make sure your satisfied computer minimum system requirements before you try to start the Movie Maker and then try to update the driver for your video card if Movie Maker does not start".

    I know that my computer meets the minimum system requirements because it came with the whole package. I've also updated my video driver correctly several times. I even uninstalled Movie Maker, re-installed. Even uninstalled the complete set of Windows Live and re-installed, but it still does not work. After a lot of searching for answers, I found the event log in which this error:

    «Activation context generation failed for "C:\Program Files (x 86) \Windows Gallery\MovieMaker.Exe".» Manifest error or policy of the folder "C:\Program Files (x 86)" \Windows Live\Photo Gallery\WLMFDS.

    I don't know, but I think it's causing my movie maker does not start. I looked around even more of an answer to this question on how to resolve this error, and I couldn't find anything so far. Microsoft support said that I have nothing to do and it will solve automatically. Alas, I got this error whenever I tried to open Movie Maker (the time is equal to the time I tried to open it).

    What can I do to fix this?

    Thanks in advance.

    You can go ahead and post in the forums alive in dealing with the problem with Live Movie Maker specifically. Please do not hesitate to answer, in the case where you are facing in the future other problems with Windows.

  • Underpayment to destroy the VM in vRA7

    Hello.  I run a POC in the House for vRA7 and that you have installed and configured a minimal deployment and have set up the deployment into a test vCenter.

    Everything looks good and I have created a simple model to set up a virtual Windows machine. This works as expected and the deployment is complete, and I see the resulting virtual machine in my list of items.

    However, when I try to destroy the configured virtual computer, I see the following error message

    Is it possible that the combination is be the first record? If so, I would say that check properties of the Data Source of the rule of your load for a definition header which is not matched correctly (i.e. the number of lines to skip = 1, whereas it should be 0).

    It is the only reason I could imagine that a combination of record is not loaded in a load rule by also valid.
