Hi, Im picking up this issue, because debian stretch was released, and it includes a up to date version of gtk3, which allows to create a opengl context. this example code works on stretch: https://stackoverflow.com/questions/42598360/no-glcontext-for-gtkglarea-in-gtk3-python there is already some work on gtk3: https://github.com/LinuxCNC/linuxcnc/compare/gladevcp_gtk3 merging this into master gives a few conflicts, and I cant get it to work. I would like to port gremlin to gtk3, but I need some place to start, like a minimalistic gui example that uses gtk3 and imports gremlin. Norbert mentioned that it would be no problem to port the widgets.
