第一种,使用lambda表达式
1 QFuture<void> future = QtConcurrent::run([=]() ); 4 ...第二种,使用成员函数
调用QByteArray的成员函数split()
1 // call 'QList<QByteArray> QByteArray::split(char sep) const' in a separate thread 2 QByteArray bytearray = "hello world"; 3 QFuture<QList<QByteArray> > future = QtConcurrent::run(bytearray, &QByteArray::split, ','); 4 ... 5 QList<QByteArray> result = future.result();调用非成员函数:
1 // call 'void QImage::invertPixels(InvertMode mode)' in a separate thread 2 QImage image = ...; 3 QFuture<void> future = QtConcurrent::run(&image, &QImage::invertPixels, QImage::InvertRgba); 4 ... 5 future.waitForFinished(); 6 // At this point, the pixels in 'image' have been inverted上一篇:Qt QCustomPlot 使用教程
