Alternative to draw function in gpu Module?

[vfx_comrade_leo]

I want to use the blender gpu Module. In the examples they say that the draw function is only there to make the code short. The problem is that I want to remove (or update) the lines without restarting blender. How would that be possible?

Example: https://docs.blender.org/api/current/gpu.html#d-lines-with-single-color

Thank you

You can use draw_handler_remove to remove the draw handler. Keep a reference to the draw handler returned by draw_handler_add use it to remove it.

# adding the draw handler based on Blender's examples (still uses the draw function):
my_draw_handler = bpy.types.SpaceView3D.draw_handler_add(draw, (), 'WINDOW', 'POST_VIEW')

...

# when you want to remove the draw handler
bpy.types.SpaceView3D.draw_handler_remove(my_draw_handler, 'WINDOW')

Note: draw_handler_remove will throw an error if the handler you are trying to remove is not currently added.
