Thank you. I got the problem solved. The program crashed everytime I tried to select a dragger. It actually had nothing to do with the dragger itself. Just the CommandManager pointer was somehow unaccessable (deleted?).
I manually called the ref() and then it worked fine. I paid a lot to learn the smart pointer. Still don't quite understand when they should be used. Why many pointers in the examples are just pointers not ref_ptr. ----- Original Message ---- From: Mike Weiblen <[EMAIL PROTECTED]> To: OpenSceneGraph Users <[email protected]> Sent: Thursday, June 19, 2008 12:38:50 PM Subject: Re: [osg-users] help on picking and draggers? there is the osgpick example. do you have a small example that demonstrates the issues you're struggle with? -- mew On Thu, Jun 19, 2008 at 8:40 AM, Xinyu Zhang <[EMAIL PROTECTED]> wrote: > Is there any document or tutorial on how to use picking and draggers in OSG? > I am struggling on this.
