Writing bullets and number text GTKTextView

How can i add bullets and number using GTKTextView in Linux working environment.

First begin with reading

• Text Widget Overview from Wayback Machine (archive.org)
• Gtk - 3.0: Text Widget Overview from docs.gtk.org

Then I think you need to combine

• GtkTextTag from Wayback Machine (archive.org)
• Gtk.TextTag from docs.gtk.org

(for formatting the text) with some creativity.

This is all assuming you want bullet/numbered lists.
