<div>Hi </div>
<div> </div>
<div><font face="Courier New" size="2"><span style="font-size:10pt;">I updated my vtk from Paraview’s vtk of paraview 4.4 to 5.2 where now the opengl2 backend is enabled by default. I programmed an own app which uses qvtkwidget2 to visualize a histogram of
an image which worked on my old paraview4.4’s vtk. Now I get the error message “Error: no override found for 'vtkContextDevice2D'”. I found some threads which say that you have to link vtkRenderingContextOpenGL, but on opengl this file is called vtkRenderingContextOpenGL2
and I am already linking it… </span></font></div>
