how to create click event dynamically???

[Radhika]

I have created Buttons dynamically.Now I want to create "click" event on them how can i do that ?

for(raw=1;raw<=20;raw++)
        {
             for(clm=1;clm<=5;clm++)
             {
                  QPushButton *pb = new QPushButton();
                  pb->setIcon(hdd_img);
                 grid->addWidget(pb,raw,clm,1,1);
 
                  connect(pb, SIGNAL(clicked()), s_map, SLOT(map()));
 
 
             }
        }

for(raw=1;raw<=20;raw++)
        {
             for(clm=1;clm<=5;clm++)
             {
                  QPushButton *pb = new QPushButton();
                  pb->setIcon(hdd_img);
                 grid->addWidget(pb,raw,clm,1,1);

                  connect(pb, SIGNAL(clicked()), s_map, SLOT(map()));


             }
        }

To copy to clipboard, switch view to plain text mode 

I have tried this but it is not working
I want to show details of some object on that button click and want to access the ID of that button

Will generate mouse press event :
 
 QPushButton *pb = new QPushButton();
 connect(pb, SIGNAL(pressed()()), s_map, SLOT(map()));
 
 QMouseEvent* press = new QMouseEvent(QEvent::MouseButtonPress, pb->rect().center(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
 QApplication::postEvent(pb, press);

Will generate mouse press event :

 QPushButton *pb = new QPushButton();
 connect(pb, SIGNAL(pressed()()), s_map, SLOT(map()));

 QMouseEvent* press = new QMouseEvent(QEvent::MouseButtonPress, pb->rect().center(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
 QApplication::postEvent(pb, press);

If you want mouse click :

QPushButton *pb = new QPushButton();
 connect(pb, SIGNAL(clicked()()), s_map, SLOT(map()));
 
    QMouseEvent* press = new QMouseEvent(QEvent::MouseButtonPress, pb->rect().center(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
    QMouseEvent* release = new QMouseEvent(QEvent::MouseButtonRelease, pb->rect().center(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
 
    QApplication::postEvent(pb, press);
    QApplication::postEvent(pb, release);

QPushButton *pb = new QPushButton();
 connect(pb, SIGNAL(clicked()()), s_map, SLOT(map()));

    QMouseEvent* press = new QMouseEvent(QEvent::MouseButtonPress, pb->rect().center(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
    QMouseEvent* release = new QMouseEvent(QEvent::MouseButtonRelease, pb->rect().center(), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);

    QApplication::postEvent(pb, press);
    QApplication::postEvent(pb, release);

To copy to clipboard, switch view to plain text mode 

you can refer QMouseEvent for more info

You can also just call the button's click() slot.
