Hmm, yeah, the repetition here is unfortunate. spice graphics is the
first XML device to have a repeating child element, so we don't really
have an existing example in the code to deal with it.
The 'correct' (but equally overkill) way of handling this would be to
have a separate class VirtualGraphicsChannel, and have the parent device
keep a public list or dict of Channels. It would be the most extensible,
but probably the most code.
Or you could add a hack like:
def _get_mode_prop(self, channel_type, channel_mode=None):
xpath = "./channel[@name='%s']/@mode" % channel_type
def get_mode(self):
return self._channels.get(channel_type, None)
def set_mode(self, val):
self._channels[channel_type] = channel_mode
return _xml_property(get_mode, set_mode, xpath=xpath)
def get_channel_mode(self, channel_type):
tmpprop = self._get_mode_prop(channel_type)
return tmpprop.fget(self)
def set_channel_mode(self, channel_type, channel_mode):
tmpprop = self._get_mode_prop(channel_type, channel_mode)
return tmpprop.fset(self, channel_mode)
which I'm fine with. Lightly tested to at least pass the xmlconfig.py tests.
Thanks,
