Yes, py2exe is the Windows equivalent of py2app.

PyQt is more of a GUI library, so you'll need to use something else for XML. It seems like Expat would be a good choice. Have a look at the documentation here:

http://docs.python.org/library/pyexpat.html

If I want to see @mentions in my web browser I'll just open up a tab as I normally do. I don't need this to open it. The nice thing about building a standalone Twitter app is you can create your own unique user experience.

Anyway, I was playing around with this a bit more and was able to turn this into standalone Mac OS X app with py2app. It worked pretty well.

@Hawkee I does not lock up for me.... Sorry about that binary. I just saw the title and was like this may work... Sorry. I really wanted to use the built in time line in this script. But can not find out how to do it easily.... Because the API returns XML not HTML and I am not sure if PyQt4 has a XML parasing option. Tho I will work on it. Glad you like it. For now (I heard you only like to see @s) you can change the

webbrowser.open_new_tab('http://twitter.com/') 

to

webbrowser.open_new_tab('http://twitter.com/#replies')

Thanks for going through the trouble to try it out.

I got it! It turns out PyQt 4.5 was buggy, thus the error. I compiled the recently released 4.5.1 and it worked like a charm.

So about the script. It locked up when I posted a Tweet, but it did post to Twitter. I had to reopen the script to stop the hourglass from spinning. The thing it really lacks is a built-in timeline and functionality like @mention alerts and PM support. It's a nice start and I'd love to see it grow.

The error I'm getting is this:

ImportError: cannot import name QtCore

What I don't get is why it can't use the QtCore.so file that's in the sys.path. It seems there is some sort of dependency problem or the PyQt library was compiled incorrectly.

I tried the old binary you sent me, but that's for Python 2.3 and is quite old. It didn't work at all.

@Hawkee Well... I am bummed. If you were running windows i could have sent you py2exe .exe version of this. but i have no clue what mac executable files are.... also when you try running the script (in your terminal) what error comes up? if it an import error then u did not build pyqt4 properly... however if it is something else then its myself and pls lemme know about it.... tho u probably no that :/

PATX, unfortunately I couldn't get everything to compile properly to test this. I spent a great deal of time and really don't know what went wrong. I know you probably aren't running this on OS X, but here is my plight in the comments here: http://www.oak-tree.us/blog/index.php/2009/05/12/pyqt-mac

OK updated! also @Hawkee if you need more help or want a screen shot of it you can always go to http://patx44.appspot.com/h-twt << some very help links there along with a readme.

Alllsoooo.... u need to change

    username = 'username_here'  # change 'username_here' to your twitter username.
    password = 'password_here'  # change 'password_here' to your twitter password.

to what is says to do! or it will not work! also to make the timeline button work on the gui make sure your are logged into twitter with "Remember Me" turned on. that button is simply a link to your browser cos lets face it this a SIMPLE client.

I wanted to give this a test run but I just couldn't quite get Python set up correctly for it. Maybe a list of links to each dependency would help.
