WindowDiscoverServer.h
class WindowDiscoverServer : public QMainWindow { //Q_OBJECTWhy did you comment out the
Q_OBJECTmacro? Your class needs it to implement new slots.Un-comment the macro and run qmake.

when i uncomment my compilator (Kdevelop) return this error "/home/default/projects/MainProject/WindowDiscoverServer.cpp:5: undefined reference to `vtable for WindowDiscoverServer'
p.s. I use cmake not qmake

Yes, that's why I said you need to run qmake after you uncomment it.
p.s. I use cmake not qmake
I don't know how to do it in cmake, but you can (i) uncomment
Q_OBJECT, (ii) delete your build tree, and then then (iii) rebuild everything from the beginning.
