[Qt] slot of QTimeEdit [problem resolved]

[scorpiondezer]

Hi everyone:)
I need to connect a QPushButton with QTimeEdit , for create a chronometer, I'm lost in the doc...:confused:
Thank you :)

What do you want QTimeEdit to do when the button is clicked?

[scorpiondezer]

The time run like a chrono

See documentation of QTimer. Here's an example:


QTimer *timer = new QTimer(this);
timer->setInterval(1000);
connect(timer, SIGNAL(timeout()), this, SLOT(updateTime()));
connect(button, SIGNAL(clicked()), timer, SLOT(start()));

void MyWindow::updateTime()
{
timeEdit->setTime(QTime::currentTime());
}

Thank you your code is perfect, but you use a current time, can I begin by the initialize time in QTimeEdit

Of course, refer to QTimeEdit and QTime documentations how to get/set the current time of QTimeEdit and how to add time to an existing QTime object.

Thank you very much.
The problem resolved


void Window::updateTime()

{
m_s++;
if (m_s>59)
{
m_s=0;
m_m++;

}
if (m_m>59)
{
m_m=0;
m_h++;

}

timeEdit->setTime(QTime(m_h, m_m, m_s));

}

Don't you think using QTime::addSecs() would be easier? ;)
