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. Slots aren't expected to exist indefinately after they are connected. Often slots are only used to receive a few events and are then disconnected, and the programmer needs control to decide when a slot should no longer be connected. The entry point for managing connections explicitly is the boost::signals::connection class. qt documentation: Qt - Hantering av databaser.
