I want to call a function when a button click. the implementation of the button is in the abstract class. but when I compile I'm getting this error.
This is my .h file of the base class
#ifndef HOME_H
#define HOME_H
#include<QGraphicsScene>
#include <QGraphicsScene>
#include<QPushButton>
class home
{
Q_OBJECT
public:
home();
virtual void set_home_background()=0 ;
QGraphicsScene *scene3;
QPushButton *button3;
private slots:
virtual void startgame1();
};
#endif // HOME_H
This is the base class
#include "home.h"
#include<QGraphicsScene>
#include<QGraphicsProxyWidget>
#include "QMessageBox"
home::home()
{
}
void home::set_home_background()
{
button3 = new QPushButton;
QObject::connect(button3,SIGNAL(clicked()),this,SLOT(startgame1()));
QGraphicsProxyWidget *proxy = this->scene3->addWidget(button3);
button3->setAutoFillBackground(true);
button3->setIcon(QIcon(":/Images/ng.png"));
button3->setIconSize(QSize(131,41));
proxy->setPos(130,430);
scene3->addItem(proxy);
}
void home::startgame1()
{
QMessageBox q;
q.setText("");
q.exec();
}
I'm getting this error
C:\Users\User\Documents\breakout_final\home.cpp:16: error: no matching function for call to 'QObject::connect(QPushButton*&, const char*, home*, const char*)' QObject::connect(button3,SIGNAL(clicked()),this,SLOT(startgame1()));
