    The triangular icon should be the default for the QMessageBox::warning dialog, while the red circular one is the default for the QMessageBox::critical dialog.

    In my python code I use either

    QMessageBox.warning(None,QString("..."),QString("...."))

    or the more complex

    msg = "..."
q = QMessageBox(QMessageBox.Warning, "...",  QString(msg))
q.setStandardButtons(QMessageBox.Ok);
i = QIcon()
i.addPixmap(QPixmap("..."), QIcon.Normal)
q.setWindowIcon(i)
q.exec_()

    And both of them works well.

    Eventually can you show the code you use to show the dialog ?
