    • Type: Bug
    • Status: Reported
    • Priority: P3: Somewhat important
    • Resolution: Unresolved

      Description

      QState (and therefore also QStateMachine) want the initial state to be a direct decendant of itself. For example:

      QState a;
        QState b(&a);
          QState c(&b);
      a.setInitialState(&c); // WARNING: state 0x123 is not a child of this state (0x456)
      

      There is noting preventing a "deep" state as the initial state. The state machine will then enter both b and c whenever a is entered. The check should be changed to see if the initial state has the current state as an ancestor, and not as a direct parent.
