Hi all:
I have a project that is based on Qt5.1.1 development environment and today I installed Qt5.2.0 and open the project from Qt5.1.1, I found only the project name existed, the other file(.cpp, .ui) didn't exist, are they not compatible?
It is compatible. Check the directory whether such files exist in the original directory. While opening pro file in new version, delete pro.user file and then import the pro file.
