I found this folder on an old computer. It isn't much but does demonstrate GTK3 openGL with python. run graphics.py - I ran it with wheezy. This was based on a demo I found on the net. IIRC was just trying to get panning/rotation/zoom to work right and added a couple CNC primitives. after that would be connecting it to the linuxcnc python module to gain access to gcode openGL drawing commands. Again IIRC linuxcnc module's can parse the loaded file and convert it to openGL commands then our python program would draw them.

I have started to work my way up from the hardware and currently look a little bit on the configuration, it should not be to hard to get useful graphical configuration with gschem and then I will start to look at linuxcnc. 2017-07-17 15:21 GMT+02:00 Chris Morley <chrisinnana...@hotmail.com>: > > I did the work on that branch.Gremlin can not work in gtk3. > > I did some experimental work on a gremlin substitute...it's was too much > work for me to figure out but I could dig up the code when I'm next at > home..in a couple weeks. > I think I got as far as displaying the origin and axis letters , pan as > zoom. > I would love for someone to take this on. > I quit working on the branch because of this hurdle. > > Chris M > > ----- Reply message ----- > From: "Rene Hopf" <reneh...@mac.com> > To: "EMC developers" <emc-developers@lists.sourceforge.net> > Subject: [Emc-developers] Gladevcp_gtk3 Branche > Date: Mon, Jul 17, 2017 5:47 AM > > > > 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/ [https://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-i...@2.png?v=73d79a89bded]<https://stackoverflow.com/> Stack Overflow - Where Developers Learn, Share, & Build ...<https://stackoverflow.com/> stackoverflow.com Stack Overflow is the largest, most trusted online community for developers to learn, share their programming knowledge, and build their careers. > questions/42598360/no-glcontext-for-gtkglarea-in-gtk3-python > there is already some work on gtk3: https://github.com/LinuxCNC/ [https://avatars2.githubusercontent.com/u/5650508?v=4&s=280]<https://github.com/LinuxCNC/> LinuxCNC.org · GitHub<https://github.com/LinuxCNC/> github.com LinuxCNC controls CNC machines.
