How do I print a variable value in QMessageBox?

Question

Do I need to use a QString first then put it in the msgbox? Are there any examples?

Does QString have formatting methods? You could use `sprintf` or `std::stringstream` and then pass that to `QString`. — Thomas Matthews, Jan 18 '12 at 17:17

The QMessageBox documentation has examples in it:

QMessageBox msgBox;
msgBox.setText("Put your text here");
msgBox.exec();

There are a few others in there. Please read the docs.

you can use the folowing example and you can add as many as arguments you want.

int device_count=0;
QString status = QString("Found %1 device(s):").arg(device_count);
QMessageBox::information(this, tr("Info"), status);
