Question

i have QT application that plays mp3.

when i call play() function, it plays the music until the mp3 ends. But, i want to play it for 2 seconds.

player->play();
//after 2 seconds
player->stop();

how can i control the time between play and stop?

Answer 1

使用QTimer::singleShot。如果您的播放器有一个名为的插槽，请stop()使用如下所示的单发计时器：

player->start();
QTimer::singleShot(2000, player, SLOT(stop()));
