QApplication as not "main object" ( window in dll )

[daijvid]

Hello.
I write exe without gui.
I want to write gui in dll as plugin.
Exe -> "standard main" loop.
If dll exist it load it -> show window etc.
QApplication::exec can't be run on thread, so how i can do?

Your application (main()) will have to have QApplication object.
Implement your GUI in a DLL, not problem with that.

Not good. Application isn't Qt application and can't be.

[high_flyer]

Well, then maybe you can put your non Qt application in a QThread launched by your Qt GUI when you do use the GUI, and run it normal when you don't use the GUI.

It is not as easy as i wanted ( my application is part of big application... many work ).
But now i think to start qtapplication as a process from my application.
