Showing a message dialog from an application running in fullscreen

Good day,
I have an application running in fullscreen mode. This application displays errors on a separate dialog, but hen the dialog is displayed the OS (it only runs on linux) menu bars are displayed.
Is there a way to avoid this situation?

To display dialogs I use:

Code:

---

void ErrorWindow::notifyError(const QString &msg)
{
 
    if (errWind.isNull()) //All errors are displayed on a single message box as long as the message box exists.
    {
        errWind= new QMessageBox;
        errWind->resize(500, 200);
        errWind->setModal(false);
        errWind->setText("Errors have been found. Press show details to review the error list                                                                   ");
        connect(errWind.data(),SIGNAL(buttonClicked(QAbstractButton*)),this,SLOT(clearErrors(QAbstractButton*)));
    }
    QString errtxt;
    if(messages<100)
    {
        errtxt = errWind->detailedText();
        messages++;
    }
    else
    {
        errtxt = "";
        messages=1;
    }
    errtxt.prepend(QString("%1:%2\n").arg(QDateTime::currentDateTime().toString(DATETIME_FORMAT)).arg(msg));
    errWind->setDetailedText(errtxt);
    errWind->show();
}

Thanks in advance.

I'm not quite sure what you mean by 'menu bars'?

Anyway, try parenting the dialog to the main window rather than creating it 'hanging' around.

That worked, thanks!
