@Quentin91 said in Qt Creator with MSVC2010 : no valid kit found:

The problem is that I can't download anything as I want as I work in a company

Then how you did you download Qt source code?

If online installer doesn't work you can use the offline installer.

@Daniel-Nilsson did you get the solution to this?

@Ajith_P_V , maybe, you need not RGB, but BGR model. I didn't work with graphics in qt, but in OpenCV all work was gone in BGR.

OK, so now that I have launched the program with admin rights and came back with user session, the application is working (?!?)

So it was neither a DLL or plugins problem, but just a weird right access blocking. I am sad I can't explain why I had to launch it once with admin session, but at least I am glad I solved my problem.

Thanks anyway to those who give their time to help.

@SGaist Thank you dude, setCurrentRow is what I want!

@SGaist Thank you once again!
Now, I can manage to display the folder list inside the stacked widget page using QTreeView + QFileSystemModel combo!
