Source File
#include <QtGui>
#include "digitalclock.h"
DigitalClock::DigitalClock(QWidget *parent)
: QLCDNumber(parent)
{
setSegmentStyle(Filled);
setNumDigits(8);
setStyleSheet("* { background-color:rgb(199,147,88);color:rgb(255,255,255); padding: 7px}}");
QTimer *timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(displayTime()));
timer->start(1000);
displayTime();
setWindowTitle(tr("Digital Clock"));
resize(300, 120);
}
void DigitalClock::displayTime()
{
QTime time = QTime::currentTime();
QString text = time.toString("hh:mm:ss");
if ((time.second() % 2) == 0)
{text[2] = ' ';
text[5] = ' ';
}
display(text);
}
