Sheet style dialog with Qt

Sheet style is a nice feature on macOS, to achieve it in Qt, all you need are following statements.

QMessageBox *msgBox = new QMessageBox(parent);

msgBox->setWindowFlags(Qt::Sheet);
msgBox->setText("sheet style");

msgBox->show();

Note:

• parent and Qt::Sheet are two mandatory conditions.
• msgBox-> exec(); also works, with the same effect

What does it look like?
