Embedding web browser or a screen for parsing HTML is easy in PyGTK. You only need to import the pymozembed, and add a few lines of code in your pygtk library, and you are set to go.

Here’s a sample PyGTK application that embeds a web-browser as well as a “Back” button for demonstration purpose :

import pygtk
pygtk.require('2.0')
import gtk
import gtkmozembed

class PyMoz:

	def delete_event(self,widget,data=None):
		print("Exit")
		return False

	def destroy(self,widget,data=None):
		gtk.main_quit()

	def button_clicked(self,widget,data):
		data.go_back()

	def __init__(self):
		#init mozembed
		self.moz = gtkmozembed.MozEmbed()
		#create a Vertical Box Container to whole the browser
		#and the "Back Button"
		box = gtk.VBox(False,0)

		#create a basic GTK+ window
		win = gtk.Window()
		win.add(box)

		#create and connect "Back" button, to add functionality
		self.button = gtk.Button("Back")
		self.button.connect("clicked",self.button_clicked,self.moz)

		#include both back button and the browser in the vertical box
		#and the GTK+ window
		box.pack_start(self.button,False,False,0)
		box.pack_start(self.moz,True,True,0)

		#load the URL
		self.moz.load_url('http://blog.mypapit.net/')		

		#set the window title
		title=self.moz.get_title()
		win.set_title("browser demo")

		#show all the stuffs on screen
		win.show_all()

		#connect the delete_event and destroy event to make sure
		#the app quits when the window is closed
		win.connect("delete_event",self.delete_event)
		win.connect("destroy",self.destroy)

if __name__ == "__main__":
	PyMoz()
	gtk.main()
