Hi
You can set your own notify handler like this to check if you ever get messages
from osg:
class NH : public osg::NotifyHandler
{
public:
NH()
: m_out("osg_log.txt")
{
}
~NH()
{
m_out.close();
}
void notify (osg::NotifySeverity severity, const char *message)
{
m_out << message;
}
private:
std::ofstream m_out;
};
osg::setNotifyHandler(new NH);
Cheers,
Sergey.
