Building a Qt dll
I need to build a .dll for an existing program to use. I would like to use Qt for this dll. The dll will need, in addition to providing functions to the using program, a GUI to fetch parameters from the user.
Can someone please point me to an existing Qt dll or tutorial on how to do this?
Welcome to Qt Developer Network!
I think you should learn more about making Project as Dynamic Libraries in Qt and create your one. I believe it will be the best solution. There are many resources on the Net which can help you.
The wiki has lots of info: https://qt-project.org/wiki
In particular, this section might be useful: https://qt-project.org/wiki/How_to_create_a_library_with_Qt_and_use_it_in_an_application
Hope it helps :-)
