Show progress bar in Blender 2.8 exporter Does Blender 2.8 have default Progress Bar in GUI (not in console) to show exporting progress for my exporter plugin (something similar to DrawProgressBar from Blender.Window in Blender 2.49) ?
Thanks
This is all I've found so far:

import bpy

win = bpy.context.window_manager

win.progress_begin(0, 100)

for i in range(1,100) :
    win.progress_update(i)

win.progress_end()


Update

According to the source code this was intended to be a real progress bar, but that was back in 2013, unfirtunately it seems to have fallen into obscurity.
