How do i connect messageBox when it is clicked, to a slot? - qt

Question

I want to create a messagebox asking question whether a user want to play again or not. When user clicks either a button , it performs a task. The task is defined in a slot. How can i connect the button click to that slot??
QMessageBox::StandardButton reply=QMessageBox::question(this,"GAME Over-Do you want to play again?");
connect(QMessageBox,SIGNAL(buttonClicked()),this,SLOT(box());
it shows QMessageBox is a class, and is unable to connect it to that slot. I want to connect to that slot.

There is different ways to use QMessageBox. You could use blocking static functions of QMessageBox and check response like that:
QMessageBox::StandardButton reply = QMessageBox::question(this,"Title", "GAME Over-Do you want to play again?");
if(reply == QMessageBox::Yes)
{
//call your slot
//box();
qDebug() << " Yes clicked";
}
else
{
//Game over
qDebug() << "game over";
}
but this will block execution of your code until user clicks some button in message box.
If you need your code run forward without waiting for user response you could use QMessageBox in non-blocking way:
QMessageBox * msg = new QMessageBox(QMessageBox::Question, "Title", "GAME Over-Do you want to play again?", QMessageBox::Yes| QMessageBox::No, this);
connect(msg,SIGNAL(accepted()),this,SLOT(box()));
connect(msg,SIGNAL(rejected()),this,SLOT(gameover()));
msg->show();
qDebug() << "Not blocked";
