Unexpected return value from QMessageBox::exec()

[walle19]

Hi All,
My platform: Linux kubuntu 14
QT Version: 4.7.1

I generate a QMessageBox with two standard buttons as seen in the following code:

   QMessageBox msgBox;
    msgBox.addButton(tr(sn.c_str()), QMessageBox::NoRole);
    msgBox.addButton(tr(sn.c_str()), QMessageBox::YesRole);

    int ret = msgBox.exec();
    switch (ret) {
    case QMessageBox::YesRole:
    {
       break;
    }
    case QMessageBox::NoRole:
    {
    	break;
    }
    default:
    	break;
    }

This code generates a qmessagebox with two buttons.
When I press the right button QMessageBox::NoRole the return value from exec() is zero;
Even though the documentation states:
When using a QMessageBox with standard buttons, this functions returns a StandardButton value indicating the standard button that was clicked.

Any idea what I am doing wrong ?

Thanks

@walle19 You should at least try with the latest Qt4 version (which is 4.8.7 if I remember correctly).

Since you don't call the QMessageButton with StandardButtons you have to use clickedButton() to determine the selected button.

Side note:

@walle19 said in Unexpected return value from QMessageBox::exec():

tr(sn.c_str())
