The traffic light has - three lights: Red, yellow and green. The traffic light transitions from - one light to another (red to yellow to green to yellow to red again) at - certain intervals. - - \snippet examples/statemachine/trafficlight/main.cpp 0 - - The LightWidget class represents a single light of the traffic light. It - provides an \c on property and two slots, turnOn() and turnOff(), to turn - the light on and off, respectively. The widget paints itself in the color - that's passed to the constructor. - - \snippet examples/statemachine/trafficlight/main.cpp 1 - - The TrafficLightWidget class represents the visual part of the traffic - light; it's a widget that contains three lights arranged vertically, and - provides accessor functions for these. - - \snippet examples/statemachine/trafficlight/main.cpp 2 - - The createLightState() function creates a state that turns a light on when - the state is entered, and off when the state is exited. The state uses a - timer, and as we shall see the timeout is used to transition from one - LightState to another. Here is the statechart for the light state: - - \image trafficlight-example1.png - \omit - \caption This is a caption - \endomit - - \snippet examples/statemachine/trafficlight/main.cpp 3 - - The TrafficLight class combines the TrafficLightWidget with a state - machine. The state graph has four states: red-to-yellow, yellow-to-green, - green-to-yellow and yellow-to-red. The initial state is red-to-yellow; - when the state's timer times out, the state machine transitions to - yellow-to-green. The same process repeats through the other states. - This is what the statechart looks like: - - \image trafficlight-example2.png - \omit - \caption This is a caption - \endomit - - \snippet examples/statemachine/trafficlight/main.cpp 4 - - The main() function constructs a TrafficLight and shows it. - -*/ |
