connect(this,SIGNAL(sgSetTheThreshold(float)), this, SLOT(SetTheThreshold(float))); @ I think it should work in both ways.[/quote] No, it will not work both ways. You can connect a signal to a slot, or to another signal, or with Qt 5 even to a normal member function or a functor or a lambda function. But you cannot connect a slot to anything.

Signals and Slots - Qt Documentation Signals and slots are loosely coupled: a class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.
