# ControlService.py
#
# A simple app which duplicates some of the functionality in the
# Services applet of the control panel.
#
# Suggested enhancements (in no particular order):
#
# 1. When changing the service status, continue to query the status
# of the service until the status change is complete. Use this
# information to put up some kind of a progress dialog like the CP
# applet does. Unlike the CP, allow canceling out in the event that
# the status change hangs.
# 2. When starting or stopping a service with dependencies, alert
# the user about the dependent services, then start (or stop) all
# dependent services as appropriate.
# 3. Allow toggling between service view and device view
# 4. Allow configuration of other service parameters such as startup
# name and password.
# 5. Allow connection to remote SCMs. This is just a matter of
# reconnecting to the SCM on the remote machine; the rest of the
# code should still work the same.
# 6. Either implement the startup parameters or get rid of the editbox.
# 7. Either implement or get rid of "H/W Profiles".
# 8. Either implement or get rid of "Help".
# 9. Improve error handling. Ideally, this would also include falling
# back to lower levels of functionality for users with less rights.
# Right now, we always try to get all the rights and fail when we can't
