[Qt-interest] how to set up loop with timer

[Hannu Shemeikka]

Hi,

You could use something like this:

timer = new QTimer(this);
connect(this->timer, SIGNAL(timeout()), rThread, SLOT(yourSlotName()));
this->timer->start(2000); // 1 = 1 ms

This fires slot 'yourSlotName' in rThread (another QThread class) every
2 seconds.

Or in the constructor of your thread:

timer = new QTimer(this);
connect(this->timer, SIGNAL(timeout()), this, SLOT(yourSlotName()));
this->timer->start(2000); // 1 = 1 ms
