I'm trying to create a Python notification application. To make it short here is what I wanted to do :
1. Checking my gmail account
2. Display a notification with the number of unread mails
3. Display a button that permits me to open chromium (using a system call)
For now everything looks just fine. The checking mail part was kind of easy. I serialised my unread mail count so that the notification doesn't show up every single minute. It only displays if I have a new mail.
Where I'm blocking is that I don't know how to create the main gtk loop so that I can handle the button signal.
Here is my code :
#!/usr/bin/python
from gi.repository import Notify, Gtk, GLib
from urllib.request import FancyURLopener
from datetime import datetime, date, time, timedelta
import os.path, sys, getopt
from subprocess import call
serialisedvalue=0;
serialiseddate=0;
def callback():
call(["chromium", "gmail.com"])
def serialise(unread):
try:
f = open("mailcount", "w")
try:
f.write(unread+"\n") # Write a string to a file
f.write(datetime.now().strftime('%b %d %Y %I:%M%p'))
finally:
f.close()
except IOError:
pass
def deserialise():
global serialisedvalue
global serialiseddate
try:
f = open("mailcount", "r")
try:
serialisedvalue = f.readline().rstrip()
serialiseddate = datetime.strptime(f.readline(), '%b %d %Y %I:%M%p')
finally:
f.close()
except IOError:
pass
def notif(unread):
Notify.init ("New Mail")
if unread != "1":
Hello=Notify.Notification.new ("New mail","You have "+unread+" unread mails","/usr/share/icons/Faenza/actions/96/mail-forward.png")
else :
Hello=Notify.Notification.new ("New mail","You have "+unread+" unread mails","/usr/share/icons/Faenza/actions/96/mail-forward.png")
Hello.add_action('action', 'Read', callback, None, None)
Hello.show ()
def main(argv):
notify=0
forced=0
try:
opts, args = getopt.getopt(argv,"nf",['notify','force-notify'])
except getopt.GetoptError:
print("unreadgmail.py [-n --notify] [-f --force-notify")
sys.exit(2)
for opt,args in opts:
if opt in ("-n", "--notify"):
notify=1
elif opt in ("-f","--force-notify"):
forced=1
url = 'https://%s:%s@mail.google.com/mail/feed/atom' % ("myaccount", "mypassword")
opener = FancyURLopener()
page = opener.open(url)
contents = page.read().decode('utf-8')
ifrom = contents.index('<fullcount>') + 11
ito = contents.index('</fullcount>')
unread = contents[ifrom:ito]
print("Unread messages : "+unread)
if notify==1 and forced==0:
if os.path.exists("mailcount"):
deserialise()
else:
serialise(unread)
deserialise()
if unread != "0":
if unread != serialisedvalue:
notif(unread)
serialise(unread)
elif ((datetime.now() - serialiseddate) > timedelta(hours=1)):
notif(unread)
if forced==1:
notif(unread)
GLib.MainLoop().run()
if __name__ == "__main__":
main(sys.argv[1:])
I remember that my notifications used to work fine with pygtk and pynotify. Though I want to update my code and since I lost the last code, I don't have a clue on that. Calling Gtk.main() in my main just block the program until I kill it.
I'm using Gnome3.6, Archlinux and python3.3.
So does anyone know how to "wait" for the signal handler to be clicked before the program ends ? In fact it runs fine, but the script just end when the notification is displayed and it doesn't wait for the signal.
Thanks a lot :)
EDIT : A bit more details of my problem :
As you can see, the program already ended and is not waiting for a signal. That's what I'm trying to solve right now.
