The solution: manually set up your package module:

import os
import sys
import imp
def setup_virtual_package(name, path=os.curdir):
    """ Sets up a package at the given path with a given
     name """
    modulePath = os.path.abspath(path)
    f, fn, suffix = imp.find_module('__init__',
         [modulePath])
    imp.load_module(name, f, fn, suffix)
    sys.modules[name].__path__ = [modulePath]

Now import myapp.something works like a charm.

This is usually solved by making the application a package. This allows for import myapp.drawers.gtk from everywhere inside your application. To make it a package though, you need to add the parent directory in the sys.path list. But unfortunately this also includes all other subdirectories of the parent directory as packages.

However, when the package module (eg: myapp) was already loaded, then the path from which myapp was loaded is used to find the submodules (eg: myapp.drawers.gtk) and sys.path isn’t looked at, at all. So, here is the trick:

import sys
import os.path

p = os.path.dirname(__file__)
sys.path.append(os.path.abspath(p+"/.."))
__import__(os.path.basename(p))
sys.path.pop()

Note that this script doesn’t work when directly executed, because the __file__ attribute is only available when loaded as a module.

Save this script as loader.py in the root of your application. import loader from the main script in your app, and you’ll be able to import modules by myapp.a.module, where myapp is the root directory name of your application.
