Transitions configuration

SetThis page describes how to set up transitions between the three States created in the previous operation. InThese state transitions can be configured in the State Machine Editor,Editor. 

More information about state transitions arecan setbe usingfound Transitions. This transition consists of a Sender, Condition, and Action. Therefore, if the set Condition is evaluated as "true," the set Action is executed.here.

State Transition ConfigurationsConfiguration

The Transition function of the State Machine Editor isdefines usedhow and when the system moves from one state to set up transitions between states.another. Transitions are indicated by connecting eachtwo statestates with an arrow.

Finally, each State Transition's 'Check Click Condition Behavior' has to be configured with a sender - the control that emits the click event. We have set up IndicatorLeft and IndicatorRight to send click events, so they can be configured as senders.
