In fact, the actual underlying evas object creation was deferred, as was applying properties to the object. For evas, the deferring was done because you couldn't create evas objects without immediately tying them to a canvas, which worked against our earlier requirement of being able to move objects between canvases. You could do something similar here with candy, further abstracting and deferring object creation, which will let you more conveniently take care of all that in the clutter thread. I'm a bit surprised you didn't do it this way to begin with. I should have been paying attention to the candy check-ins, I would have said something. :) > I have no idea what the code does.

Eventually we'll just remove that code anyway, once 0.6 is old enough. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Freevo-devel mailing list Freevo-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freevo-devel
[Freevo-devel] kaa.candy changes proposal (was: Kaa r3378 - in trunk/candy: . src/libcandy src/widgets)

Thanks. While looking at your changes I see again a design flaw in
kaa.candy. I noticed it before when you proposed the layout stuff you
did for kaa.canvas.
Right now a kaa.candy.Widget IS a clutter.Actor. This exposes the
clutter API to the kaa.candy user making some stuff impossible.
E.g. widget.get_width() will return the real object width and can not
respect alignments. And set_width could never support '100%' as value.
So I propose that a kaa.candy.Widget HAS a clutter.Actor. I see the
following advantages:
- Thread-safe because we do not modify a real clutter actor. One
single now_render function could be created to calculate stuff and
create the actors in the gobject mainloop
- Hide clutter API the user should no use
- Support layout
What do you think?

I have no idea what the code does. It was copied from tidy. Maybe tidy
is already updated to 0.8

There is clutter.__version__
