#include// create a QTimer object QTimer *timer = new QTimer(this); // set the interval to 1000ms (1 sec) timer->setInterval(1000); // connect the timeout signal to a slot function connect(timer, SIGNAL(timeout()), this, SLOT(myFunction())); // start the timer timer->start();
#includeThis example sets up a QTimer object that will trigger the `updateProgressBar()` function every 0.5 seconds, updating a progress bar with new data. Package library: Qt Core Overall, the QTimer class is part of the Qt Core library, which provides essential non-GUI components for Qt applications.#include // create a QTimer object QTimer *timer = new QTimer(this); // set the interval to 500ms (0.5 sec) timer->setInterval(500); // connect the timeout signal to a slot function that updates the progress bar connect(timer, SIGNAL(timeout()), this, SLOT(updateProgressBar())); // start the timer timer->start();
