Derive signals from base class? [Solved]
i basically have a base class that define a few signals of its own. I then want to use this class as a base for serveral other classes i plan to use in my project. the problem is when i try to use any of the signals in the base class in a derived class, i get compile errors saying "undefined reference to signalName." the errors go away if i redefine these signals in the derived classes but i don't want to do this.
does Qt not allow inheritance of signals? i'll post a code example if need be.
Hi and welcome to devnet,
Yes the signals can be emitted from subclasses. Please post your code example
Hi and thanks for the welcome. I think i managed to fix my problem, i ended up completely deleting the the files in my build folder as a way to force the complier to start over and that seem to have worked. the entire project now complies perfectly fine.
i am curious as to why this would happen though. i have done several test builds before, i just always assumed the complier would update files that were changed. i guess it missed a few at some point.
Godmode99! Yes. It happens some time . So u have to use clean. Please tag it as a [Solved]. thanx.
