QStateMachine animation with QFinalState, bug?

nen777w

Sorry I don't understand your question.
What "condition" you mean?

m_pSS - it's initial state (m_slide_mashine->setInitialState(m_pSS);)
then after assignProperty() I do m_slide_mashine->start();

I mean that with that line for example: m_pSS->addTransition(m_pFS); as soon as your state machine enters the m_pSS state it will go to the m_pFSstate hence your animation not working as you expect. Thus my question, shouldn't you have a condition to transition from m_pSS to m_pFS ? For example a mouse click, number of animation repetition etc.

Oh, understand! :-)
No condition is not required.
And sorry for my mistake in first post, when i said "animation is not working" I mean that after call m_slide_mashine->start() we immediately go from m_pSS -> m_pFS -> QFinalState (i.e. without duration) , but when I do not use QFinalState animation work as expected (with duration as I set in pAni->setDuration() ).

SGaist

It happens precisely because you didn't put any condition for the transition between the two states. If you take a look at the Simple State Machine example, the condition to change state is a mouse click.

So you have to determine what should trigger the transition between m_pSS and m_pFS and use the adequate QAbstractTransition subclass.

Sorry but I don't understand again.
Why I need "condition" when API allow do that without it?
And why animation is broken only when I try to use QFinalState?

SGaist

The animation is not broken.

Like I already wrote: m_pSS->addTransition(m_pFS); means that as soon as your state machine enters the m_pSS state it will transition to m_pFSthus the state machine will stop since it's a final state.

I understand.
Thank you!

SGaist

You're welcome !

So you could make it work the way you wanted ?

nen777w

Yes. Thank you!

SGaist

Great !
