[C++/QT] QFuture delay method

Posted on by joris

With credits for ChatGPT which after several promts still coulnd’t make 100% functional code. But it gave me the broad idea of the code I could use.

#include <QTimer>

QFuture<void> delay(int milliseconds)
{
    QSharedPointer<QFutureInterface<void>> futureInterface(new QFutureInterface<void>());
    QTimer::singleShot(milliseconds, [futureInterface]() {
        futureInterface->reportFinished();
    });
    return futureInterface->future();
}

It’s simple, It’s elegant. And somehow it isn’t in the Qt codebase for as fas as I could find.
