    Default Access instantiated objects from C++

    Hey,


    how can I access instantiated objects from C++?

    e.g.:

    I have a .qml file:


    Qt Code:
    1. MyItem {
    2. task: "doThis"
    3. // ...
    4. }
    5. MyItem {
    6. task: "doThat"
    7. // ...
    8. }
    9. // and further more
    To copy to clipboard, switch view to plain text mode 

    How can I now iterate through this file from a C++ application?
    I'd like to check the 'task' property from each item.


    thanks

    Your items are likely to be available as context properties of the declarative context.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    hey wysota,

    thanks for your answer, but could you explain that with a little example?

    Take a look at QDeclarativeContext::contextProperty() and also read about making your C++ objects available for QML. What you want is using the same mechanism in the other direction.
