Code to test pid handling messages:
{{{#!python
from win32con import WM_QUERYENDSESSION
from win32gui import EnumWindows, GetClassName, IsWindowEnabled,
IsWindowVisible
from win32process import GetWindowThreadProcessId
def get_hwnds_for_pid(pid):
def enumwins_cb(hwnd, hwnds):
if IsWindowVisible(hwnd) and IsWindowEnabled(hwnd):
# print(GetClassName(hwnd), GetWindowThreadProcessId(hwnd)[1])
if pid == GetWindowThreadProcessId(hwnd)[1]:
hwnds.append(hwnd)
return True
hwnds = []
EnumWindows(enumwins_cb, hwnds)
return hwnds
def shutdown_pid(pid):
win32api.PostMessage(get_hwnds_for_pid(pid)[0], WM_QUERYENDSESSION)
}}}
