Re: [osg-users] Qt 5.4 + OSG 3.2.1 + Multithreading
Hi DizL et. al, No one has actually submitted that change, it's the first I've ever heard of it. So just waiting for something to be merged when nothing has been passed on is well, going to require alot of patience. I have look at the diff and it looks like a hack to me, and not suitable to be merged. It rather looks like the author of the modification doesn't know about GraphicsConext::releaseContext() which is how graphics contexts are supposed to release their threads and allow a graphics context to be re-assigned to another thread. While GraphicsContext::makeCurrent() is meant to acquire the context for a new thread. All the capabilities are their in the base class so one should not need to modify it. The modifications would need to be done in osgQt itself. Robert.

Re: [osg-users] Qt 5.4 + OSG 3.2.1 + Multithreading
Hi, We're currenltly just embedding our osg window into Qt as foreign windows as decribed here: http://forum.openscenegraph.org/viewtopic.php?t=13602. This has worked well for us since Qt 5.4 although there are a few quirks, notably the lack of keyboard focus in the osg window and also you cant paint over the top with a QPainter. But if you just want to embedd an osg window in a Qt widget then it works fine. No problems with multithreading either. I've tried most of the fixes mentioned above and got them to work at the time, but then ran into problems in later versions of Qt when the cannot access QOpenGLContext in a different thread errors appeared again. I managed to fix the errors for a couple of Qt versions before giving up trying to keep up.

[osg-users] OSG/OpenGL users in Israel?
I'm going to be in Tel Aviv in a couple of weeks, and figured I'd ask here if anybody in that area was doing anything interesting in the OSG and OpenGL space.

Hi João, It sounds like you need to include the ValueObject header: #include osg/ValueObject Cheers, Farshid On Tue, Mar 10, 2015 at 3:38 PM, João joao.henrique.pi...@hotmail.com wrote: Everything else is working fine, but when I try to use the set/getUserValue functions, this happens: Error 2 error LNK2001: unresolved external symbol public: bool __cdecl osg::Object::getUserValueint(class std::basic_stringchar,struct std::char_traitschar,class std::allocatorchar const ,int )const (??$getUserValue@H@Object@osg@@QEBA_NAEBV?$basic_string@DU?$char_traits@D @std@@V?$allocator@D@2@@std@@AEAH@Z) C:\Users\Joao\documents\visual studio 2013\Projects\VRProjectDemo\VRProjectDemo\Main.obj VRProjectDemo Error 1 error LNK2001: unresolved external symbol public: void __cdecl osg::Object::setUserValueint(class std::basic_stringchar,struct std::char_traitschar,class std::allocatorchar const ,int const ) (??$setUserValue@H@Object@osg@@QEAAXAEBV?$basic_string@DU?$char_traits@D @std@@V?$allocator@D@2@@std@@AEBH@Z) C:\Users\Joao\documents\visual studio 2013\Projects\VRProjectDemo\VRProjectDemo\Main.obj VRProjectDemo Anyone have a clue about which lib I am missing?
