Qt 4.4.1 and Visual Studio 2015

[Arthur]

I need to migrate our projects to Visual Studio 2015. We still have the Qt 4.4.1 Library. When compiling the folowing errors are given:

To copy to clipboard, switch view to plain text mode 

If I switch the platform toolset to VS 2012 in the project properties it compiles without errors. Is there any way to solve this?

Best regards,
Arthur

Those are only warnings, not errors.
