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 +*/ |
