Qt timer problem

[anh5kor]

Hello,

I want to add a time on my design which starts with formate 00:00:00 and my number should keep on increasing every seconds.
I tried to add the code

showtime()
{
QTime time =QTime::currentTime();
    QString time_text = time.toString("hh:mm:ss");
    ui.clock->setText(time_text);
}
constructor()
{
 QTimer *timer = new QTimer(this);
connect(timer,SIGNAL(timeout()),this,SLOT(showtime()));
timer->start();
}

showtime()
{
QTime time =QTime::currentTime();
    QString time_text = time.toString("hh:mm:ss");
    ui.clock->setText(time_text);
}
constructor()
{
 QTimer *timer = new QTimer(this);
connect(timer,SIGNAL(timeout()),this,SLOT(showtime()));
timer->start();
}

To copy to clipboard, switch view to plain text mode 

but I am getting my system time.
I want it should start from zero and keep on increasing every second.
Please let me know some solution.

I guess this solution is sufficient for you

constructor : m_time(QTime(0,0,0))
{
   ui.clock->setText(m_time.toString("hh:mm:ss"));
}
 
showtime 
{
   m_time = m_time.addSecs(1);
   ui.clock->setText(m_time.toString("hh:mm:ss"));
}

constructor : m_time(QTime(0,0,0))
{
   ui.clock->setText(m_time.toString("hh:mm:ss"));
}

showtime 
{
   m_time = m_time.addSecs(1);
   ui.clock->setText(m_time.toString("hh:mm:ss"));
}

Added after 6 minutes:

To be more precise:

constructor : m_time(QTime::currentTime())
{
   ui.clock->setText(QTime(0,0,0).toString("hh:mm:ss"));
}
 
showtime
{
   ui.clock->setText(QTime(0,0,0).addSecs(m_time.secsTo(QTime::currentTime())).toString("hh:mm:ss"));
}

constructor : m_time(QTime::currentTime())
{
   ui.clock->setText(QTime(0,0,0).toString("hh:mm:ss"));
}
     
showtime
{
   ui.clock->setText(QTime(0,0,0).addSecs(m_time.secsTo(QTime::currentTime())).toString("hh:mm:ss"));
}

Use QElapsedTimer instead of QTimer.

Use QElapsedTimer instead of QTimer.

You meant QElapsedTimer instead of QTime?

QTimer is an "active" class, it has a signal.

Of course QTime, thanks anda_skoa for correction.
