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. How to identify which signal called the slot? | Qt Forum The only way is to pass that info as a signal/slot parameter. It goes against the design of signals/slots to do so though. Receiver should not have to know anything about the sender, and, in particular, there might not be a sender at all if the slot was called directly.

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal. Signal/Slot design pattern — signalslot 0.1.1 documentation Signal/Slot is a widely used pattern, many frameworks have it built-in including Django, Qt and probably many others. If you have a standalone project then you probably don’t want to add a big dependency like PyQt or Django just for a Signal/Slot framework.
