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:
Qt Code: 
  1. void ErrorWindow::notifyError(const QString &msg)
  2. {
  3.  
  4.     if (errWind.isNull()) //All errors are displayed on a single message box as long as the message box exists.
  5.     {
  6.         errWind= new QMessageBox;
  7.         errWind->resize(500, 200);
  8.         errWind->setModal(false);
  9.         errWind->setText("Errors have been found. Press show details to review the error list                                                                   ");
  10.         connect(errWind.data(),SIGNAL(buttonClicked(QAbstractButton*)),this,SLOT(clearErrors(QAbstractButton*)));
  11.     }
  12.     QString errtxt;
  13.     if(messages<100)
  14.     {
  15.         errtxt = errWind->detailedText();
  16.         messages++;
  17.     }
  18.     else
  19.     {
  20.         errtxt = "";
  21.         messages=1;
  22.     }
  23.     errtxt.prepend(QString("%1:%2\n").arg(QDateTime::currentDateTime().toString(DATETIME_FORMAT)).arg(msg));
  24.     errWind->setDetailedText(errtxt);
  25.     errWind->show();
  26. }
To copy to clipboard, switch view to plain text mode 

Thanks in advance.
