Register one or more Python packages with the following interface, and surrounding Pyblish projects may utilise them where needed. Such as in file menu of the Autodesk Maya integration.
"""Create or unhide the most desireable GUI."""
Multiple GUIs may be registered, it is up to the consumer of the registered GUIs to determine which to use and how. The design intent is to enable registration of a series of default GUIs, along with custom or bespoke ones.
Here is the basic structure expected by the register_gui function.
"""My package description"""
from PySide import QtGui
my_gui = QtGui.QMessageBox()
Once the package is on your PYTHONPATH, you may register it like so.
