Qt - Saptamana a 13-a Laborator

Qt - Saptamana a 13-a Laborator



Pentru cei care s-au incurcat in codul ceasului, (o fi oare din cauza saptamani a 13-a), va transcriu aici sursele finale , in varianta care ruleaza pe Qt 5.9

Fisierul: main.cpp

//------------------------ main.cpp----------------------------------------//
#include <QApplication>
#include <QLCDNumber> // pt QT 5.x Linux Ubuntu
#include <QTimer>     // Includeti si QTimer
#include "digitalclock.h"
int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  DigitalClock clock;

  #if defined(Q_OS_SYMBIAN)
     clock.showMaximized();
  #else
     clock.show();
  #endif
  return app.exec();
}
//----------------------------------------------------------------------------//


Fisierul:digitalclock.h
#ifndef DIGITALCLOCK_H
#define DIGITALCLOCK_H
#include <QLCDNumber>

class DigitalClock : public QLCDNumber
{
    Q_OBJECT
public:
    DigitalClock(QWidget * parent = 0);
private slots:
    void showTime();
};

#endif // DIGITALCLOCK_H


Fisierul:digitalclock.cpp

 //----------------------- digitalclock.cpp------------------------------------//
#include <QtGui>
#include <QLCDNumber>
#include <QTimer>

#include "digitalclock.h"
//! [0]
DigitalClock::DigitalClock(QWidget *parent)
  : QLCDNumber(parent)
{
    setSegmentStyle(Filled);

    QTimer *timer = new QTimer(this);
    connect(timer, SIGNAL(timeout()), this, SLOT(showTime()));
    timer->start(1000);

    showTime();
    setWindowTitle(tr("Digital Clock"));
    resize(150, 60);
}
//! [0]


//! [1]
void DigitalClock::showTime()
//! [1] //! [2]
{
  QTime time = QTime::currentTime();
  QString text = time.toString("hh:mm");
  if ((time.second() % 2) == 0)
    text[2] =  ' ';
  display(text);
}
//! [2]
