Don't work AnimationGroup (QSequentialAnimationGroup, QParallelAnimationGroup)

beqa

I am learning from a book. I do single animation, but in group don't work.
QSequentialAnimationGroup *group = new QSequentialAnimationGroup;
trow me one error:
QSequentialAnimationGroup : no appropriate default constructor available
and QParallelAnimationGroup *group = new QParallelAnimationGroup; has 3 errors

QParallelAnimationGroup: undeclared identifier
group: undeclared identifier
3.syntax error: identifier "QParallelAnimationGroup"

looks like you are just missing a #include <QParallelAnimationGroup>

@VRonin said in don't work AnimationGroup (QSequentialAnimationGroup,QParallelAnimationGroup):

yes it works. thank you

beqa

but it is bad,that Sequential animation need other #include <QSequentialAnimationGroup> library

Hi can I ask Why is that bad?

beqa

Hi
In my opinion, it is less convenient to write 3 libraries, when you want animation

VRonin

you can use #include <QtGui> and forget about the rest but you are just dumping a lot of useless stuff on your compiler.

beqa

yes, but at first i taught in QPropertyAnimation library would has all this features ( Why should not be? ), nor in my book read to need another library :D

@beqa
Well most likely it has later been split to own files / classes later.
It's best not to have tons of bundles as then big projects will suffer a lot if everything includes
heaps of extra classes.

@mrjj
yes you are right, thanks
