Hi Dhrubajyoti,
The textview widget has text tags built in that you can use to draw rectangles
around text. If you want to draw a rectangle to block out text you can match
the background and foreground colors. This code works on Ubuntu16.04, GTK3.18
and Python2.7. Give it a try and see if something similar will work for what
you are working on.

tag = textbuffer.create_tag("blue_tag", background="blue",

textbuffer.apply_tag(tag, start, end)
