* Remove default error stateEskil Abrahamsen Blomfeldt2009-06-233-65/+34
| | | | | | | | | Having an implicit default error state in the graph which the user has not added is unintuitive and ugly. Rather than have a default error state, we stop execution of the machine and print an error message when the machine has run-time errors. If a user wishes to prevent errors from stopping the machine, you can set one or more error states explicitly.
* perform normalization of signatures for signal transitionsKent Hansen2009-06-222-8/+15

* perform all property assignments of initial state that's nestedKent Hansen2009-06-171-2/+2
| | | | | | If the machine's initial state is nested, a set of states will be entered, and we need to do the property assignments of all of them.
* bring back QAbstractTransition::triggered() signalKent Hansen2009-06-174-0/+23
| | | | | | It's been requested by several users. Since we have QAbstractState::{entered,exited}() signals, we should have this one as well.
* prevent subclasses from emitting entered() and exited()Kent Hansen2009-06-171-0/+3

* make sure signal transition is correctly unregistered/re-registeredKent Hansen2009-05-222-14/+18
| | | | | | When the signal or senderObject is changed while the state is active, the transition needs to be unregistered _before_ either property is changed, only _then_ can it be re-registered.

* Make it impossible to have root state as source or target of transition or ↵Eskil Abrahamsen Blomfeldt2009-05-073-4/+26
| | | | | | | | | | | as error state Since the root state has no ancestors, it cannot be source or target in transitions since there will be no LCA for the transition, which is required for the algorithm of enterStates and exitStates. In SCXML the root state cannot be target or source of a transition. By the same logic, it cannot be an error state. The root state will always have a valid machine, since it's added to a machine immediately, which makes this code possible.

* Fix infinite loop when source and target of transition are in different treesEskil Abrahamsen Blomfeldt2009-05-072-15/+34
| | | | | | | | | | | The SCXML algorithm depends on the guarantee that there is always an LCA regardless of the state list. The case where the targets are in a different tree than the source (e.g. if you have not given the target state a parent) is a bug. The fix is to set an error when this happens in exitStates() and exit states as if the pending error states were the target states. In enterStates we will detect the error and skip the step of selecting states to enter, and instead just enter the pending error states. This breaks transitions to and from the root state, which is not supported by the SCXML algorithm.
* Make sure machine enters error state if history state has no default stateEskil Abrahamsen Blomfeldt2009-05-071-10/+10
| | | | | | | | Keep searching the parent hierarchy for error states even if a state in the hierarchy cannot be cast to QState. Also make currentErrorState==0 an assert, since there should always be an error state (we default to the special initialErrorState if we are unable to find anything else), otherwise the machine might get into an undefined state (e.g. configuration is empty)
* Remove superfluous codeEskil Abrahamsen Blomfeldt2009-05-061-7/+0
| | | | | | | We have gone back to the old definition of implicit start values where the a new default start value is sniffed every time the animation is restarted, so we do not need to emulate this behavior ourselves anymore. Behavior should be identical.
* Fix bogus default start value when interrupting an animation that has anEskil Abrahamsen Blomfeldt2009-05-061-5/+7
| | | | | | | | implicit end value. We need to stop the animation prior to setting the end value to an invalid variant, otherwise the current value of the property will be updated based on the new end value and randomness will occur.

* add event as argument to onEntry(), onExit() and onTransition()Kent Hansen2009-05-0518-62/+72
| | | | | | | | | Accessing the event can be useful. E.g., onEntry() can do some common event processing regardless of which transition caused the state to be entered; onTransition() can be used in combination with eventTest(), where eventTest() would first check that the input matches some criteria, and then the actual processing of that input would be done in onTransition.
