[TOC] ## QObject ## 常用函數 ## startTimer 通過 startTimer 觸發 timerEvent, 每個n時刻,觸發 ``` class MyObject : public QObject { Q_OBJECT public: MyObject(QObject *parent = 0); protected: void timerEvent(QTimerEvent *event); }; MyObject::MyObject(QObject *parent) : QObject(parent) { startTimer(50); // 每個50毫秒出發一次 timerEvent } void MyObject::timerEvent(QTimerEvent *event) { qDebug() << "Timer ID:" << event->timerId(); } ```
