Hi

I'm detecting _NET_WM_STATE_DEMANDS_ATTENTION in _NET_WM_STATE and it works fine if I make a bell character in a rxvt-uncode terminal for example. However if I set the flag on other windows it isn't detected, even though xprop sees it. So far I've tried it on a few web browsers and clementine.

self._CLIENT_LIST = dsp.intern_atom("_NET_CLIENT_LIST")
self._STATE = dsp.intern_atom("_NET_WM_STATE")
self._URGENT = dsp.intern_atom("_NET_WM_STATE_DEMANDS_ATTENTION")
tasks = root.get_full_property(self._CLIENT_LIST, Xatom.WINDOW).value

for task in list(tasks):
	obj = dsp.create_resource_object("window", task)

	try:
		props = obj.get_full_property(self._STATE, Xatom.ATOM)
		if props:
			if self.get_name(obj) == "Clementine":     
				print(props)
	except:
		continue

The above will output:

<<class 'Xlib.protocol.request.GetProperty'> serial = 95, data = {'sequence_number': 95, 'property_type': 4, 'bytes_after': 0, 'value': (32, array('I', [867]))}, error = None>

As you see it only has one property value: 867, but using xprop on it shows:

wmctrl -l:
0x02c00007  3 raven Clementine

xprop -id  0x02c00007 | grep -i atten
_NET_WM_STATE(ATOM) = _NET_WM_STATE_MAXIMIZED_HORZ, _NET_WM_STATE_MAXIMIZED_VERT, _NET_WM_STATE_DEMANDS_ATTENTION

I've just updated to the latest python-xlib to see if it works better than my
old version but it still doesn't detect it.

python-xlib-0.23
libX11-1.6.4

Any ideas?
