hi all .. so, the animation API is going through its final set of changes for 4.4. please take a look at it if you care to and give us feedback now before it's too late (as defined by "we are shipping it in 4.4 and are committed to that API").
the basic "shape" of the API is this:
* Plasma::Animator becomes a factory for Plasma::Animations
* Plasma::Animation IsA QAbstractAnimation with the bare essential pure
virtuals implemented and which takes a QGraphicsWidget that should be animated
* Plasma::AnimationGroup IsA QAbstractAnimation that wraps a
QAbstractAnimationGroup (this is the part i'm least sure about atm...) and
makes switching from parallel to sequential easy (personally, i think Kinetic
should have made parallel vs sequential a property, not introduced two
different classes; it's a hassle). however, if we feel that the parallel-
>sequential switching is not worth it, we can simply kill this class and make
people deal with the slightly unwieldy QAnimationGroup directly. i'm kind of
leaning in that direction, tbh, even though i dislike parts of
QAnimationGroup's design.
basically, it's a QGrahicsView-specific set of Plasma-standardized animations
implemented in little convenience classes so that it's simpler to use Kinetic,
particularly from scripts but also C++. they still mix-and-match nicely with
plain Kinetic classes, so it's not an either-or-choice, these are just some
pre-made ones for us to use extensively throughout plasma code (less code,
more consistency)
we still have one large outstanding bit of work left, and that is to port the
animations away from the use of the previous API revision's "render()" method
and make them proper QAbstractAnimations. see the Fade animation for how this
should look if you'd like to pitch in. the ones with render calls still are:
grow.cpp
pause.cpp
pulser.cpp
rotation.cpp
rotationstacked.cpp
Slide should also probably have its internal QPropertyAnimation removed so
it's as simple/straightforward as Fade is.
