This module provides a few shortcuts to accessing resources on the class path in a uniform and transparent manner. The generic methods for this are getResource() and getResourceAsStream(). The difference between the two is only that the first one fully loads the resource and returns the object, while the second one only opens the resource as a stream and returns the stream. The resources module also contains specialized shortcuts for loading image icons for use in UI elements (loadImageIcon()) or plain Images (loadImage()).
The proper path to the resource to be loaded depends on the runtime environment. You may need to remove the / prefix from the path for resource loading to work. This seems to hold true at least for applications deployed via Java Web Start.
You may find it convenient to create your own shortcuts for resource loading that only take a file name (assuming you keep your resources in a single location). This would look something like the following:
from swingutils.resources import loadImageIcon loadImageIcon = lambda filename: loadImageIcon('application/resources/%s' % filename)
