    Hi,
    why when i press no button the program will close?
    @void MainWindow::closeEvent(QCloseEvent *event){
    QMessageBox msg(this);
    msg.setText("Are you sure you want to Quit?");
    QAbstractButton *no=msg.addButton(tr("No"),QMessageBox::ActionRole);
    QAbstractButton *yes=msg.addButton(tr("Yes"),QMessageBox::ActionRole);
    if(msg.clickedButton()==no){
    event->ignore();
    }
    else{
    event->accept();
    }
    msg.exec();
    }
    @

      Hi,

      1. addButton() returns void so no point in using it to compare.
      2. exec() will return the value of what you have clicked.

      Have a look at the example "here":http://qt-project.org/doc/qt-5/qmessagebox.html#the-property-based-api.

      Later you can use the return value of exec() to call ignore() on "No" to avoid closing of the program.
