<QT 기초> 딜레이(delay) 추가하기

참고 : doc.qt.io/qt-5/qtimer.html#QTimer

 

1. Class 추가

메뉴에서 Class 를 추가한다.

Timer Class 추가

File tree

4. Timer.h 

Timer Class 구조체 생성

#ifndef TIMER_H
#define TIMER_H
#include <QTimer>

class Timer : public QObject
{
    Q_OBJECT
public:
    Timer();
    QTimer *mytimer;
public slots:
    void MyTimerSlot();
};

#endif // TIMER_H

 

3. Timer.cpp 코딩 

 

#include "timer.h"
#include <iostream>

Timer::Timer()
{
    //create a timer
    mytimer = new QTimer(this);
    //setup signal and slot
    connect(mytimer,SIGNAL(timeout()),
            this,SLOT(MyTimerSlot()));
    mytimer->start(1000);
}
void Timer::MyTimerSlot()
{
    std::cout << "\nMYtimerSlot";
}

4. Main.cpp 코딩

 

#include <QCoreApplication>
#include <iostream>
#include <QTimer>
#include "timer.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc,argv);
    Timer mytimer;
    std::cout << "\nHellow workd of craft (iostream)\n";
    return a.exec();
}
