How to change font of a QMessageBox in Qt?

I was trying to build a simple application with a QComboBox and a QPushButton. The idea is to populate the QComboBox with a list of all available fonts in the system. When the user selects a font and presses the QPushButton then a QMessageBox appears with the font selected. Now how to do it?

Solution

  • The solution is using the setFont() method of the QMessageBox 

    QMessageBox *msg = new QMessageBox(QMessageBox::Information, "Message with font",
                         "This message is in font: " + ui->comboBox->currentText(),
                          QMessageBox::Ok | QMessageBox::Cancel, this);
QFont font = QFont(ui->comboBox->currentText());
msg->setFont(font);
msg->exec();

    Where combobox is QComboBox used.
