Rss reader for systray

Question

Started working on a little project. An rss reader that sits in the systray. Its pretty bare right now, but its downloading feeds and opens them in the browser when i click on them.

Answer 1

Fixed that bug, kind of, i'm not sure if it's the proper solution, but it seems to work. Relevant code:
def build_submenu(self, feed):
menu = Gtk.Menu()
for i in feed.entries:
menuitem = Gtk.MenuItem()
menuitem.set_label(i.title)
menuitem.connect("activate", self.construct_command(i.link))
menu.append(menuitem)
return menu
def construct_command(self, link):
def open_link(self):
webbrowser.open(link)
return open_link
Lambda expression inside a loop seems to overwrite itself during every iteration, like here:
l = []
for i in range(10):
l.append(id(lambda x: x*i))
print(l)
# OUT: [139721358186400, 139721358186400, 139721358186400, 139721358186400, 139721358186400, 139721358186400, 139721358186400, 139721358186400, 139721358186400, 139721358186400]
print(l.count(l[0]))
# OUT: 10
As you can see, id of the lambda expression is the same in every iteration, despite being a different function (i is different in each lambda), so when the for loop finishes, you'll end up with only one callable object, that every menu item executes on activation.
EDIT:
After a bit of screwing around, i found that this also works:
menuitem.link = i.link
menuitem.connect("activate", lambda x: webbrowser.open(x.link))
Instead of passing the arbitrary address to the lambda it just extracts link from the menu entry itself.
