Hi, I am running an app in an PyQt QGLWidget. If the window is minimized, and the method for rendering the object that should be displayed is called, I get the error 'OpenGL.error.Error: Attempt to retrieve context when no valid context' (included below), when glColorPointerd() is called. Is there: * a way to check whether a valid context is set? * force the context to be set? Best regards, Mads glColorPointerd(colors) File "/home/mpi/svn/quantumconnect/external-libs/build/lib/python2.6/site-packages/OpenGL/wrapper.py", line 410, in wrapperCall cArgs, File "/home/mpi/svn/quantumconnect/external-libs/build/lib/python2.6/site-packages/OpenGL/arrays/arrayhelpers.py", line 66, in __call__ contextdata.setValue( self.constant, pyArgs[self.pointerIndex] ) File "/home/mpi/svn/quantumconnect/external-libs/build/lib/python2.6/site-packages/OpenGL/contextdata.py", line 49, in setValue context = getContext( context ) File "/home/mpi/svn/quantumconnect/external-libs/build/lib/python2.6/site-packages/OpenGL/contextdata.py", line 32, in getContext """Attempt to retrieve context when no valid context""" OpenGL.error.Error: Attempt to retrieve context when no valid context |
