// repeaters are both signals and slots, which are designed as intermediate
|
|
// pass-throughs for signals and slots which don't know about each other (for
|
|
// modularity or encapsulation). This eliminates the need to declare a signal
|
|
// handler whose sole purpose is to fire another signal. The repeater connects
|
|
// to the originating signal using the 'repeat' method. When the repeated
|
|
// signal fires, the repeater will also fire.
