    \title QtQuick Examples - Threading
    \example quick/threading
    \brief This is a collection of QML Multithreading examples.
    \image qml-threading-example.png

    Threaded ListModel contains a ListView and a ListModel. The ListModel is updated asynchronusly in another thread, and the results propagate back to the main thread.
    A timer requests updates from the worker thread periodically:
    \snippet examples/threading/threadedlistmodel/timedisplay.qml 0

    Inside the worker thread, the ListModel is synchronized once the data is finished loading:
    \snippet examples/threading/threadedlistmodel/dataloader.js 0

    WorkerScript contains an example of using a WorkerScript to offload expensive calculations into another thread. This keeps the UI from being blocked. This example calculates numbers in Pascal's Triangle, and not in a very optimal way, so it will often take several seconds to complete the calculation. By doing this in a WorkerScript in another thread, the UI is not blocked during this time.

    When the UI needs another value, a request is sent to the WorkerScript:
    \snippet examples/threading/workerscript/workerscript.qml 0
    The workerscript then is free to take a really long time to calculate it:
    \snippet examples/threading/workerscript/workerscript.js 0
    When it's done, the result returns to the main scene via the WorkerScript element:
    \snippet examples/threading/workerscript/workerscript.qml 1
