I have an application that runs on both Windows and Linux. To prevent multiple instances, we are using QSingleApplication. On Windows, if the app is started from the desktop this works fine but if it's started from a console a second instance can be started.
So I've decided to try a suggestion using QSharedMemory. I create an instance of QSharedMemory with a unique key in main. Then if I can call create() and it succeeds there is only one app running. This works fine in windows. It works fine in Linux as long as the running app doesn't crash. Then the shared memory object is not released and no future instances can be created until a reboot. This is described in the help for QSharedMemory. I would like to use the same method for both OS and also, we expect to go to Qt 5 and QSingleApplication, QServices etc don't seem to be supported. Is there some cross platform way to achieve this and one that will be supported by Qt5? _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
