[osg-users] referenced memory management across dlls/exe (Windows only)
Hi all,
I am facing a problem with memory clean-up when mixing the place of
allocation across dlls and the executable. Let say I have main executable
that loads dlls (plugins) in which I allocate memory using referenced
pointers. On exit, those pointers that were allocated in one of the dlls
got stucked in
if (needDelete)
{
signalObserversAndDelete(true,true);
}
Ln 198 in Referenced. And this is Windows only, on Mac or Linux I
don't have this problem.
If I clean these pointers from the originated dll, it works ok, otherwise not.
Any clue?
Thanks as allways!
Nick

Re: [osg-users] referenced memory management across dlls/exe (Windows only)
also I am using Qt Creator and MinGW (whatever the last version is). I know
in Visual Studio you can specify the /MD option to use shared CRT libs and
to avoid this problem. Any MinGW gurus around with hints?

Hi KOS,
I have just got to reviewing your proposed change to
Animation.cpp. What name would you like me to use when attributing
this fix when I check it in?
Cheers,

Hello everybody!
osgAnimation/Animation.cpp
bool Animation::update (double time, int priority)
OpenSceneGraph 3.2.1:
case ONCE:
if (t _originalDuration)
return false;
Should be:
case ONCE:
if (t _originalDuration)
{
for (ChannelList::const_iterator chan = _channels.begin();
chan != _channels.end(); ++chan)
(*chan)-update(_originalDuration, _weight, priority);
return false;
}
maybe :)

[osg-users] Custom CompositeViewer Events
Hi, I have a program which is using a custom viewer derived from osgViewer::View. In this custom view's scene may be some custom types derived from osg::Geode. I'll call these MyView and MyGeode for the sake of the post. MyView's are put inside a osgViewer::CompositeViewer. All this works great. Now, I want to send custom events to MyView and MyGeode. My original hope was that I could just register a handler on MyView and MyGeode and do something like compositeViewer-accept(new MyEvent), but it doesn't seem that easy. I ended up creating a MyCompositeViewer that has an accept function on it that takes MyOsgGaEventVisitor and then create a MyGUIEventHandler which attempts to dynamic_cast osgGA::GUIEventAdapter to MyEventAdapter. MyGUIEventHandler is created with a pointer to its owning MyView and then can make calls into MyView based on the event. I haven't started working on getting the event into MyView's scene and onto MyGeode's yet because this design is challenging my sanity. This approach works, but seems like a mess. Before I get too far down this rabbit hole, what is the RIGHT way to get a custom event sent from a top-level CompositeViewer to its subordinate views and then onto the view's scene nodes? The examples in OSG seem to address parts of this problem, but I can't see a solution to the entire scope of the problem. Another way to phrase the question might be: How do I create a custom OSG-wide event that can be responded to by all osgViewer::View's and osg::Geode's alike? Thank you!
