After stackoverflow answered my previous question on here about my Wiimote left/right click issue, Not only can I move the mouse cursor, I can now left/right click on things. I now have one more question.
What do I use in python to get the title of the开发者_运维百科 current active window? After googling 'X11 Python Window Title', 'Linux Python Window Title' and things similar, All I've found is win32 and tkinker (again?), which isn't what I need.
If you could help, That would be awesome!
EDIT
best way:
import gtk
import wnck
import glib
class WindowTitle(object):
def __init__(self):
self.title = None
glib.timeout_add(100, self.get_title)
def get_title(self):
try:
title = wnck.screen_get_default().get_active_window().get_name()
if self.title != title:
self.title = title
print title
except AttributeError:
pass
return True
WindowTitle()
gtk.main()
Alternative way:
from subprocess import PIPE, Popen
import time
title = ''
root_check = ''
while True:
time.sleep(0.6)
root = Popen(['xprop', '-root'], stdout=PIPE)
if root.stdout != root_check:
root_check = root.stdout
for i in root.stdout:
if '_NET_ACTIVE_WINDOW(WINDOW):' in i:
id_ = i.split()[4]
id_w = Popen(['xprop', '-id', id_], stdout=PIPE)
for j in id_w.stdout:
if 'WM_ICON_NAME(STRING)' in j:
if title != j.split()[2]:
title = j.split()[2]
print "current window title: %s" % title
I noticed that wnck requires GTK event loop to update the active window. There is no such problem with Xlib:
import Xlib
import Xlib.display
disp = Xlib.display.Display()
window = disp.get_input_focus().focus
# Get active window class and name
window.get_wm_class()
window.get_wm_name()
killown's xprop-based solution can be compacted into a single (though lengthy) statement:
import subprocess
def GetActiveWindowTitle():
return subprocess.Popen(["xprop", "-id", subprocess.Popen(["xprop", "-root", "_NET_ACTIVE_WINDOW"], stdout=subprocess.PIPE).communicate()[0].strip().split()[-1], "WM_NAME"], stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()[0].strip().split('"', 1)[-1][:-1]
With ewmh
:
from ewmh import EWMH
wm = EWMH()
win = wm.getActiveWindow()
win_name = win.get_wm_name()
print(win_name)
I think python-wnck might be useful if you want to handle Windows & workspaces & such. I can't find the Python docs immediately, but according to the docs for the libwnck C library that it wraps, it has a wnck_screen_get_active_window() method.
My solution:
import wnck
disp=Display()
default_screen=wnck.screen_get_default()
default_screen.force_update()
active_window=disp.create_resource_object('window', default_screen.get_active_window().get_xid())
title=active_window.get_wm_name()
Is the problem to find out which window is active or what the title is? Getting a window's title is easy:
MainWindow.title()
,where MainWindow is the window's name. No idea about active window though. Never had multiple windows.
