Subject: Re: [osg-users] setEventCallback vs setUpdateCallback
Hi Matteo,
The event and update traversals can be adjusted to traversal all
children or just active ones via the NodeVisitor::setTraversalMode
method.
The fact that event and update are set differently by default is
something that probably needs to be mulled over by myself.

Hi,
I'm using a sequence node that selects each time different objects.
Each object has its own callback.
I'd like to implement an application where the objects callbacks are only
called when they are selected by the sequence node.
I initially used the setUpdateCallback method to add the callbacks to
object.
But...what i see is that on each osg traverse, all the callbacks are
called.
So i tryed to use setEventCallback...and it seems to work properly.
From the doxygen documentation i don't see any differences between the
two
methods.
So ...my question is...Are the eventCallbacks called before or after the
viewer.Update()?How many times they are called for each traverse?..
Thank you so much!
Matteo
