    Default How to pass the Java script [var] from qml to .H/.CPP file

    Hi,

    I had fetched the list of products and stored in javascript var in main.qml. Now I want to pass the var to ListProduct.cpp.
    How should I pass the var.

    Code Snippets:

    main.qml [in button click event]

    var varResultArray;

    varResultArray = idPortalSearchItems.results[1];

    objHomeController.eveWriteXMLFile(varResultArray) //passing var from main.qml

    ListProduct.h
    ----------------
    Q_INVOKABLE bool eveWriteXMLFile(var ResultArray);//Showing the error.


    Query: What i have to declare in the declaration of the method in LisProduct.h to receive the var as the parameter.


    Thanks in advance.

    Assuming you get the data from C++ in the first place, why not just use the same data type?

    Looks a lot like trying to make your life as hard as possible by artifically doing things in JavaScript instead of doing it in C++.

    Cheers,

    Default How to pass the javascript var from qml to CPP?

    I want to pass the results which stored in javascript var from the main.qml to the writeXML.cpp.
    I can see the count, the searchitems are fetched and want to write in XML format.

    How can I achieve this.

    Code snippet:

    var varResultArray;

    varResultArray = idPortalSearchItems.results[1];

    Query:

    How Can I pass it by Javascript var Ex:
    objHomeController.eveWriteXMLFile(varResultArray ); //Passing an Js variable


    writeXML.h
    ------------

    What will be the datatype of the argument of the method?
    Ex:
    Q_INVOKABLE bool eveWriteXMLFile(??????? varResultArray ); //What will be the datatype?




    Thanks In advance.
