[Solved] Does anyone know how to solve this error I get in c++

mshefiti

So, the errors that I get are:

symbol(s) not found for architecture x86_64

linker command failed with exit code 1 (use -v to see invocation)

These 2 errors I get after I declare/define the setters and getters in myControllerFactory CLASS. The problem is not there if I only declare the slot cppButtonSlot(buttonId).
Here is the complete code so far related to my problem.

If anyone could help, would be really really really helpful.
I am a beginner in C++, so I may have stupid mistakes in the code.

Thank you all for your help.
