Recently for my biogen project I needed a way to create pop-up text entries for users using virtualenv. Sadly, neither wxPython nor TkInter would work easily without ugly hacks involving symlinking to system directories. Eventually I worked out that Gtk would work via pip. However, I couldn't find sample code anywhere that ran synchronously(not via signals), so I could wait to grab the users input before proceeding along execution. So I cooked up some sample code that might help others.

from pgi.repository import Gtk, GObject

class EntryWindow(Gtk.Window):

    def __init__(self, ask_title="Title", ask_body="Body", message="Message"):
        Gtk.Window.__init__(self, title=ask_title)
        self.set_size_request(200, 100)

        self.timeout_id = None

        vbox = Gtk.Box(orientation=Gtk.Orientation.VERTICAL, spacing=6)
        self.add(vbox)

        label = Gtk.Label(message)
        vbox.pack_start(label, True, True, 0)

        self.entry = Gtk.Entry()
        self.entry.set_text(ask_body)
        vbox.pack_start(self.entry, True, True, 0)

        hbox = Gtk.Box(spacing=6)
        vbox.pack_start(hbox, True, True, 0)

        button = Gtk.Button(label="OK")
        button.connect("clicked",self.on_ok_button_clicked)
        vbox.pack_start(button, True, True, 0)

    def on_ok_button_clicked(self,button):
        Gtk.main_quit()

    def run(self):
        self.show_all()
        Gtk.main()
        result = self.entry.get_text()
        self.destroy()
        return result

The import uses pgi.repositories not gi.repositories as I needed it to be compatible with PyPy for speed.

To then run this code(and grab it's input), use something like this.

win = EntryWindow("My Title", "Enter Some Text", "Some message")
response_text = win.run()

It's a pretty basic app that lists the ten nearest running events in your area. There was a few new pieces of tech(for me) involved. The app was built with Appcelerator's Alloy framework, which I must admit I quite like for rapid development of cross platform mobile apps(hopefully …

Last week I moved from Debian to Linux Mint and setup Thunderbird as my new mail client(replacing mutt). Sadly for some reason Thunderbird started tanking and wiped all the mails from my mailserver without actually downloading anything.

I could've restored the mails from a backup but instead I figured …

Say you have an app with a set of models that aren't being managed by Django, you're going to run into trouble when it comes time to run unit-tests against these. What I mean is if in the model meta you have something like this

class MyClass:

class Meta:

PostGis is awesome, I think I already established this in this post. However when you start writing django tests you might start getting errors complaining that certain postgres libs cannot be found. This is because you've failed to create a proper postgres_template database for your test database to work with …
