Multiple definitions error: one in my file and one in the moc file.

Question

I have a class called FindAndReplaceBar, whose implementation is this:

#include \"FindAndReplaceBar.h\"
#include 
#include 
#inc         


        

Answer 1

Judging by your connect calls (signal to signal), I assume if we look at your header file, you will have declared findNext(), findPrevious(), replace(), replaceAll() as signals, but you must not implement signals - they just need to be declared in the header.

From the Qt docs on signals

Signals are automatically generated by the moc and must not be implemented in the .cpp file. They can never have return types (i.e. use void).
