Hi, there was a discussion about using Qt5 as a plugin in the past on this mailing list. Just check the archive.
In general, for VST2 your implementation of AEffEditor::open() should create the thread creating the application object and invoking exec(). That is the latest point you can use before it has to be created. Not sure if you need to have Windows supported for your project, but if you do then you need to take care that the arguments passed to your own qapplication object are exactly the same the host has been given (GetCommandLineA(),...). I remember some checks via GetCommandLineA and not using QCoreApplication::arguments() and hence the mismatch caused an assert.
