Using LGPL version of Qt,can we check a Qt dll file in our app using md5/sha to see if the dll file is the original Qt dll file or not?It would prevent users from updating the dll with a newer version,so is it against LGPL licence?

Well technically it is possible.Using LGPL version of Qt,can we check a Qt dll file in our app using md5/sha to see if the dll file is the original Qt dll file or not?
I am not a legal guy, but IMO there is not a voilation of LGPL, because user can still replace the dll file with version of his choice. Apprantly your application will not work with other versions of dll, but hey that is your application's restriction, not dll's restriction.It would prevent users from updating the dll with a newer version,so is it against LGPL licence?
When you know how to do it then you may do it wrong.
When you don't know how to do it then it is not that you may do it wrong but you may not do it right.
