In the preferences you have this setting:
# Set to 'none' to turn off drawing whitespace, 'selection' to draw only the
# whitespace within the selection, and 'all' to draw all whitespace
Now I've created an addon which only draws the indenting, but I can't get the right style. Does anyone know if it's possible to get the dots, because this is not a theme setting I'm not sure if I can.. This is my current line, giving the whitespace the same style as comments:
view.addRegions("HighlightWhitespace", region, "comment")
Thanks in advance.
