I know the feeling :) I am having difficulties trying to figure
out the likelihood of circular references if the type is switched
from observer_ptr to ref_ptr. I noticed that there are some
clients that call the osgWidget::Callback constructor and pass
"this" as the obj argument. That is, the callback IS an
osgWidget::Window. Currently, I am not thinking clearly enough to
identify the repercussions of the aforementioned behavior if the
callbacks were stored as a ref_ptr. See osgwidgetnotebook for example.
I've looked at the code and the way the osgwidget examples use the
addCallback() method and it looks to me like the list should be a
ref_ptr<>, I looked for potential for circular references and didn't
spot any. I've modified the code to use a ref_ptr<> and the osgwidget
examples I tried all worked fine so have now checked this change into
svn/trunk.
Thanks! I will test it some more on my end and post back to the list if
I find any unintended consequences.
Regards,
Judson
