Dear Dan,
Thank you for your prompt answer! The problem is that our application
development is bound to QtCreator and it seems that the Qt5 support of
VTK provides a plugin file for QVTKWidget and not for QVTKOpenGLWidget.
Inspecting the example RenderWindowNoUiFile.cxx, I cannot see how
QVTKOpenGLWidget can be placed in an UI form file even if its class can
be defined in the C source. In the widget list of QtCreator I have only
QVTKWidget because of the plugin and no QVTKOpenGLWidget is available in
it. Thanks four your help.
Kind regards,
Zoltan
