From your response, it sounded like GtkGLArea should be working--I
installed a newer version of GTK+ and it works fine. Cool. On 12/19/16 15:31, Emmanuele Bassi

You're not even saying which platform and operating system you're using. If you're using Linux or Windows: until GTK+ 3.20, the OpenGL support in GTK+ required an implementation of OpenGL 3.2+ core profiles; in 3.20 I added support for legacy, GL 3.0 profiles, which are basically the lowest we can get in order to get a decent GL API. If you're using macOS: there's no GL integration for this platform.Will a newer GTK work better?It depends on the platform. On Linux and Windows, most likely. Nothing happened on the macOS backend to improve the situation. Ciao, Emmanuele. |
