[python-win32] Cleanly Close System Tray Process

[Gregory Piñero]

Ok I figured out how to do it:

Here's the code I made mostly from copying the examples.  If anyone
could tell me how the code works, that would still be appriciated, for
example why/how do I need this function _MyCallback?

My code:

import sys
import win32process, win32api, win32pdhutil, win32con, win32security
import win32event, msvcrt, win32gui

def get_all_windows():
    """Returns dict with window desc and hwnd,
    don't ask me how it works!"""
    def _MyCallback( hwnd, extra ):
        """Helper function for above??"""
        hwnds, classes = extra
        hwnds.append(hwnd)
        classes[win32gui.GetClassName(hwnd)] = hwnd
    windows = []
    classes = {}
    win32gui.EnumWindows(_MyCallback, (windows, classes))
    return classes

def request_windows_to_close(list_window_descs_to_close):
    """Send me a list of stuff to close such as:
stuff_to_close=['OP15_OmniPage_Agent_Class',]"""
    classes=get_all_windows()
    for windesc_to_close in list_window_descs_to_close:
        if classes.has_key(windesc_to_close):
            win32gui.PostMessage(classes[windesc_to_close],
win32con.WM_CLOSE, 0, 0)
            print 'requested closure with', windesc_to_close
        else:
            print 'Did not find a window desc. as',windesc_to_close
