[Qt] slot of QTimeEdit [problem resolved]

Hi everyone
I need to connect a QPushButton with QTimeEdit , for create a chronometer, I'm lost in the doc...
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());
}

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());
}

To copy to clipboard, switch view to plain text mode

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));
 
}

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?
