Typedef Documentation
| typedef uint32_t QSignal |
QSignal represents the signal of an event.
The relationship between an event and a signal is as follows. A signal in UML is the specification of an asynchronous stimulus that triggers reactions [UML document ptc/03-08-02], and as such is an essential part of an event. (The signal conveys the type of the occurrence-what happened?) However, an event can also contain additional quantitative information about the occurrence in form of event parameters. Please refer to the document Brief Introduction to UML State Machines) for more information about state machine concepts.
