    Description

      AttributeError: 'PySide2.QtGui.QOpenGLFunctions' object has no attribute 'glShaderSource'
      

      Furthermore, glShaderSource is also missing in the https://doc.qt.io/qtforpython-5/PySide2/QtGui/QOpenGLFunctions.html

       

      Does anyone use QOpenGLFunctions with PySide2? Because how then you can use it without shaders? It seems that the binding is missing for a long time. 

       

      Is there any quick workaround for a missing binding? Ex. add the binding by yourself to the QOpenGLFunctions object. I'm using PySide2.

       


      from OpenGL import GL
      from PySide2 import QtGui
      
      
      if __name__ == "__main__":
          app = QtGui.QGuiApplication()
          off_screen = QtGui.QOffscreenSurface()
          off_screen.create()
          if off_screen.isValid():
              context = QtGui.QOpenGLContext()
              if context.create():
                  context.makeCurrent(off_screen)
      
                  ###
                  f = QtGui.QOpenGLFunctions(context)
                  shader = f.glCreateShader(GL.GL_VERTEX_SHADER)
                  f.glShaderSource(shader, "") # <-AttributeError
                  f.glCompileShader(shader)
                  ####
