How to switch between multiple Values in a cycle?

Question

I want to switch between multiple values in a cycled kind of way. For example my variable "Counter" is initialised with 1 and by mouseclick i want it to switch to 2. Another mouseclick will change it to 3 and the next click will repeat the cycle by 1.

How do i do it by using QML?

Thank you in advance!

Answer 1

onClicked{    
switch(counter) {
  case 1:
    counter=2
    break;
  case 2:
    counter=3
    break;
  case 3:
    counter=1
    break;
  default:
    console.log("counter out of rotation)
}
}

A switch-case statement should do the trick inside an "onClicked" handler of a button. You can also do it in many different other ways. Like incrementing counter by +1 each time you press the button and add a if statement that sets counter to 1 again when it reaches the value of 4.
