StateMachine or SequentialAnimation?

Mark81

I'm looking for an advice about the best approach for this scenario.

I have to write a QML item that do the following:

it has 4 states, let's call them rise1, wait1, rise2, wait2
they runs in circle: rise1 -> wait1 -> rise2 -> wait2 -> rise1 -> ...
each state has a specific duration in time (I have 4 properties to store their duration)
a text shows the current time spent in each state
there are two kind of transitions:
- a transition between one state and another (i.e., change the color and the label of the text)
- an animation that runs during the whole duration of the state (i.e. the text moves with the same duration of the current state)

I can use a SequentialAnimation, where each step is a state. But I will have difficult to provide internal animations (the counter to be updated each second). I have to place ScriptAction here and there to initialize the timer, update the label, etc...:

SequentialAnimation {
    // state: rise1
    ScriptAction { script: initializeRise1(); }
    ParallelAnimation {
        PropertyAnimation { /* animation during rise1*/ } 
        PropertyAnimation { /* animation during rise1*/ } 
    }
    ParallelAnimation {
        PropertyAnimation { /* transition to wait1 */ } 
        PropertyAnimation { /* transition to wait1 */ } 
   }
   ScriptAction { script: finalizeRise1(); }

   // state: wait1
   // ...
}

Timer {
    id: timer
    // this will update the counter
}

function initializeRise1() {
    myLabel.text = "Rise 1"
    timer.interval = 10
    timer.running = true
}

Do you think a StateMachine can be more suitable for this use case?
