                [TOC] ## 多媒體應用 ### 聲音 方式一:直接使用 ``` QSound::play("../mySound/sound.wav"); ``` 方式二: mainwindow.h ``` QSound *sound; ``` mainwindow.cpp ``` sound = new QSound("../mySound/sound.wav", this); ... void MainWindow::on_pushButton_clicked() { // 播放按鈕 sound->play(); } void MainWindow::on_pushButton_2_clicked() { // 停止按鈕 sound->stop(); } void MainWindow::on_spinBox_valueChanged(int value) { sound->setLoops(value); } ``` 在Windows平臺上,如果設置了循環次數,那么`stop()`函數無法立即停止播放,需要完成當前的循環才可以停止播放
