Empty chromium and chrome get_wm_name.

[unai-ndz]

If I run this:

from ewmh import EWMH

ewmh = EWMH()
windows = ewmh.getClientList()

for w in windows:
    # Window name (Title)
    print(w.get_wm_name())
    print(w.get_wm_class()[1])

I get:

Chromium

Google-chrome
Terminal
Xfce4-terminal
~/gits/test_ewmh/test.py (i3close) - Sublime Text
Sublime_text

While running:
xprop | grep WM_NAME
Outputs:

WM_NAME(UTF8_STRING) = "New Issue · parkouss/pyewmh - Chromium"
_NET_WM_NAME(UTF8_STRING) = "New Issue · parkouss/pyewmh - Chromium"

and

WM_NAME(UTF8_STRING) = "duckduckgo at DuckDuckGo - Google Chrome"
_NET_WM_NAME(UTF8_STRING) = "duckduckgo at DuckDuckGo - Google Chrome"

I have tested this on a new pypenv with ewmh-0.1.6, python-xlib-0.23, six-1.11.0 and Python 3.6.5
I can't test this on others environments or browsers right now, but maybe I'm doing something wrong.
Did you have any idea or want more info?

(Not involved in this project, just thought I'd comment) Though I can't speak to why get_wm_name() is empty (beyond the possibility that it may just be unset), if you didn't know already, in order to get _NET_WM_NAME (rather than _WM_NAME) you can use EWMH.getWmName, like:

from ewmh import EWMH

ewmh = EWMH()
windows = ewmh.getClientList()

for w in windows:
    # Window name (Title)
    print(ewmh.getWmName(w))
    print(w.get_wm_class()[1])

^{Just pure speculation, but I wonder if xprop would use _NET_WM_NAME as a fallback, given that - at least on my machine - WM_NAME is usually of type STRING, rather than UTF8_STRING}

In any case, I believe the get_wm_name method is actually a method of python-xlib's Window (see here), so this problem may be entirely outside of pyewmh's control.

Indeed, Window.get_wm_name() is from python-xlib, and it reads the WM_NAME property. It is empty because of bug python-xlib/python-xlib#212

To get the (preferred) _NET_WM_NAME property, use emwh.EWMH.getWmName(window) as @creallfluharty suggested
