Hi Jeremy,
The view pointer is a bit weird for me because i manage eventhandler not
in the viewer. I put them in node event callback and then with
a switch i enable some and disable other depending of game state. So the
view pointer make osgWidget crash with my system. So an approach
like Robert explain works better with what i do.
Anyway i am happy to use osgWidget now.
Cheers,
Cedric

Jeremy,
Having used osgWidget extensively, I second what everyone has said
I would definitely be interested most in the opinions of people who have
used osgWidget most. :)
above, that the input processing/picking ought to be factored out of
the WindowManager into a separate class. osgWidget is a nice
contribution to osg, but it does have a lot of instances like this
where modularity could be improved. Input processing/picking is a
tricky thing, and it would be great to have an easy setup for swapping
in my own input handler; for instance, by default the topmost picked
widget is selected, but I might want to pick through pixels that are
textured transparent.
This is not a bad idea, but I'm not sure I fully understand how you want
them divorced. You're absolutely right that there is currently no "easy"
way to pick through a transparent pixel. Perhaps the answer here is not
to break it apart, but make creating derived WindowManagers easier?
Since you're in a refactoring mood, I also want to mention that the
biggest thing you could do to improve osgWidget is get rid of all uses
of the friend keyword. It's not good in a toolkit, especially an alpha
version toolkit, as it is mostly impossible to extend/override/bugfix
the existing stuff by inheritance. For my own project, I needed to
inherit from some of the widget classes and had to build my own
friendless version as a result.
This would be easy to get rid of, and something I could do quickly.
I can make a more extensive list of ''suggested improvements'' if you
want :)
Please do. :) The results of this discussion thread will determine if I
am way over my head or not with osgWidget. It may turn out that I've
tackled a project much larger than my understanding, and need to scrap
it entirely. :(
