Hi,
I have used the osg::ref_ptr quite a lot and never had much problems with them,
but I'm having an issue with it now.
In the main function I create a viewer (and also a DisplaySettings that is used
by it):
Code:
osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer();
osg::ref_ptr<osg::DisplaySettings> ds = new osg::DisplaySettings();
...
viewer->setDisplaySettings(ds);
...
then I also have a new class called RenderManager, who needs to viewer object
as well. I thought this was the correct way to do it:
Code:
class RenderManager
{
osg::ref_ptr<osgViewer::Viewer> viewer;
....
osg::ref_ptr<osgViewer::Viewer> getViewer() { return viewer; }
RenderManager(osg::ref_ptr<osgViewer::Viewer> viewer);
}
RenderManager::RenderManager(osg::ref_ptr<osgViewer::Viewer>):
viewer(viewer)
{
}
and I create one in main, and delete it at the end of main
Code:
RenderManager * renderManager = new RenderManager(viewer);
....
delete renderManager;
(I tried to simplify the code a.m.a.p.)
Now the delete seems to go well, but at the very end of main it will give a
access violation in the destructor of ref_ptr:
world2.exe!osg::ref_ptr<osgViewer::Viewer>::~ref_ptr<osgViewer::Viewer>() Line
35 + 0x2e bytes C++
What did I do wrong? What is the correct way to do it?
Thank you!
Cheers,
Bram
