# Set the icon for this interface action
# The get_icons function is a builtin function defined for all your
# plugin code. It loads icons from the plugin zip file. It returns
# QIcon objects, if you want the actual data, use the analogous
# get_resources builtin function.
# Note that if you are loading more than one icon, for performance, you
# should pass a list of names to get_icons. In this case, get_icons
# will return a dictionary mapping names to QIcons. Names that
# are not found in the zip file will result in null QIcons.
# Set the icon for this interface action.
# We use our own get_icon, originally inherited from kiwidude,
# later extended to allow new cal6 theming of plugins.
# For theme creators, use:
# FanFicFare/images/icon.png
# (optionally)
# FanFicFare/images/icon-for-dark-theme.png
# FanFicFare/images/icon-for-light-theme.png
