QtQuick Examples - Threading

This is a collection of QML Multithreading examples.

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:

Inside the worker thread, the ListModel is synchronized once the data is finished loading:

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:

The workerscript then is free to take a really long time to calculate it:

When it's done, the result returns to the main scene via the WorkerScript element:
