Greetings all,
First up, I'm extremely sorry if this message hits the list twice.
Having some mail problems at the moment...
I'm, err, having threading problems. I've googled through this list,
and indeed as much of the Internet as I can reach, looking for answers
and workaround to no avail. I am still just learning, really, and have
a feeling I've bitten off more than I can chew.
The situation is this:
I am trying to create a gnome applet that checks mail accounts,
displaying the usual stuff.
The files involved are:
gnoptray.py - script that launches the applet
cApplet.py - Module containing the applet class
cAccounts.py - Module containing an 'Account' class. It is built using
(not extending) imaplib and poplib. It stores an internal dictionary
of message headers, can update itself, fetch and delete messages.
guiAccount.py - GTK extensions to the cAccounts.Account class. Creates
a GUI that sets account attributes, such as username, password, etc...
The problem I'm having is with checking mail. I started by creating a
timeout that would call the update() method of a guiAccount object.
Obviously, this freezes the entire UI. I don't really want to update
the GUI while checking... I just want my menus and such to appear
while it's churning away in the background.
So I tried threads... Throwing in gtk.threads_init(), wrapping
gtk.main() in gtk.threads_enter() and gtk.threads_leave() - doing the
same with my time-out callback.
e.g
...
if interval != 0:
self.timeout_ids[name] = (gobject.timeout_add(interval,
self.check_mail, name))
def check_mail(self, name):
thread1 = threading.Thread(target=self.accounts[name].update())
thread1.start()
return 1
But nothing really worked. The UI still froze until checking was
complete. Is it worth pursuing this path?
I have tried generators, but they did not work as expected. I am now
considering writing a daemon application to do the actual mail
checking - and just feed it into the GUI through an input_add().
Either that or toss out my cAccounts.py module and build a gtk version
of imap/poplib using input_add. Any help would be much appreciated.
Cheers,
