Thanks for replaying But I've checked that, the eventQueue's ptr is 0x01513b28 and have a size of two. Btw, when the unhandled exception window pops up, the top of the call stack is the insert function of the list.
I've searched the osg mailing list archive, and found that someone else have the similar problem but had no solutions. Somebody said it might be the scopelock before the insert of the evenqueue that causes this exception. But I don't quite understand. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, September 15, 2006 11:46 PM To: osg users Subject: Re: [osg-users] qt4osg exception That looks like you have a null pointer somewhere. Looking at the line of code, I'd imagine getEventQueue() is returning null, so that'd be the first thing I'd look at.
