@ Paul : I've read your QSG, and found lots of useful information, thanks
again! In particular I've learnt by heart the part on memory management. :P
But the problem is, I'm doing everything right... All my objects are now in
ref_ptr and I still have memory leaks.
So, you're clearing a ref_ptr, and stepping through it in the debugger, and
you're watching the reference count go to zero, but delete isn't being called?
Please post a reproducer code that shows this behavior.
I had an idea : might inheritance interfere with the osg::Referenced system? I
mean, if I create my own class derived from PAT, then put it in a ref_ptr, will
it be handled correctly?
Any class derived from Referenced will work with OSG's memory management system.
'cause I've found out the following behaviour :
class CustomPAT : public osg::PositionAttitudeTransform {...}
int main()
{
PositionAttitudeTransform* myPAT1 = new PositionAttitudeTransform();
delete myPAT1; // Compilation error -> normal
CustomPAT* myPAT2 = new CustomPAT();
delete myPAT2; // Compilation OK !!! -> shouldn't be
}
Looks like you failed to declare your destructor protected.
