Is it possible to highlight an edge loop with bgl?

Can bgl work in edit mode?

I have an edge loop selected & would like to draw bgl and have those edges highlighted. Any bgl examples out there I can use.

Thanks

For blender 2.8 you have to use the Gpu module for drawing, its easier than bgl imo.

I made a module to help drawing lines, it uses gpu but abstract away the complicated functions.

This is a utility module for drawing lines in the 3D viewport on Blender 2.8
using the GPU Api

The idea is to get rid of messy draw functions and data that is hard to keep track.
This class works directly like a callable draw handler and keeps track of all the geometry data.

Thanks! I’ll see if I can store loop coordinates & assign them.
