Slots are useful for communication in component programming. This is because they emit a signal and connect new slots. A signal can have a variable number of arguments, so it’s important to use the $passSignalInformation parameter when using them.

Another type of slot function is the at-level slot. This type of function is useful for connecting objects in a program. The function also has a connection parameter that can be used to specify the location of the slot. The at-level function is also called an opcode and can be executed after another signal has been issued.
