    Good morning,
    I'd like to know what's the best approach of having only one instance running of my Qt5 based application.
    Thank you

      • There is an old one but I believe kept up-to-date, QtSingleApplication at https://code.qt.io/cgit/qt-solutions/qt-solutions.git/.
      • There are various alternatives in https://stackoverflow.com/questions/5006547/qt-best-practice-for-a-single-instance-app-protection/.
      • See https://github.com/itay-grudev/SingleApplication for code which claims to be superior to QtSingleApplication .
