Window flags equivalent to Qt::SubWindow?

[CAD_coding]

Hi,
I want to set window flags to QMessageBox such that I want to show title bar but none of the buttons like close, minmax, help, etc buttons on it.
So I got the same results by using Qt::SubWindow as a window flag.
But I am getting a qWarning() whenever the messagebox is displayed. The error is

@setGeometry: Unable to set geometry 327x69+355+94 on QWidgetWindow/'QMessageBoxClassWindow'. Resulting geometry: 333x93+355+94 (frame: 0, 0, 0, 0, custom margin: 0, 0, 0, 0, minimum size: 327x69, maximum size: 327x69).@

So I would like to know any other possible combination of flags which gives the same results?

Hi,

this code

@void Widget::on_pushButton_clicked()
{
QMessageBox dlg(this);

Qt::WindowFlags flags = dlg.windowFlags();
qDebug("FLAGS: %X", flags);
flags &= ~Qt::WindowCloseButtonHint;
flags &= ~Qt::WindowSystemMenuHint;
flags |= Qt::CustomizeWindowHint;

qDebug("FLAGS: %X", flags);
dlg.setWindowFlags(flags);

dlg.setIcon(QMessageBox::Information);
dlg.setText("Hello");
dlg.exec();

}
@

works for me
