Hi, i have not modify the exemple, i get a pixel format error when i try to do this :
traits->inheritedWindowData = *new* WindowData(winId()); Are you running this exemple on a windows operating system? i will try to run the exemple on linux. I have resolved my problem by using a QGLWidget with a compositeViewer, instead of a QWiget. The is no graphic context to set up, and the embedded graphic windows used in is more simple : *osg*::ref_ptr<osgViewer::GraphicsWindowEmbedded> _gw; instead of : *osg*::ref_ptr<osgViewer::GraphicsWindow> _gw; Thanks for your reply. 2008/3/28, #POH CHENG GUAN# <[EMAIL PROTECTED]>: > > Hi Julien, > > I did not encounter any problems running the compositeViewer with Qt4 > example, did you modify the example? > > Regards, > > CG > > > -----Original Message----- > From: [EMAIL PROTECTED] on behalf of Julien > Achard > Sent: Wed 3/26/2008 6:38 PM > To: OpenSceneGraph Users > Subject: Re: [osg-users] Multiple view in a Qt4 interface > > Okay thank you for your help, > When i try to run the exemple of composite viewer with Qt4, i get an error > in console, saying : > > Using QOSGWidget - QWidget + osgViewer creating the graphics context. > Windows Error #2000: [Screen #0] GraphicsWindowWin32::setWindow() - Unable > to cr > eate OpenGL rendering context.
