I am trying to write a replacement for Alt-TAB in Windows XP using
python Win32 extensions. I am first just trying to build a list of
all tasks that are in the taskbar; on Windows, these seem to be the
same tasks that are listed in the Alt-TAB box. I pieced together the
following code from various places:
-----------------------------------------------------------------------------
from win32gui import *
def windowEnumerationHandler(hwnd, resultList):
'''Pass to win32gui.EnumWindows() to generate list of window handle, window
text tuples.'''
if IsWindowVisible(hwnd):
txt = GetWindowText(hwnd)
if (len(txt) > 0):
resultList.append((hwnd, GetWindowText(hwnd)))
windows = []
EnumChildWindows(GetDesktopWindow(), windowEnumerationHandler, windows)
for w in windows:
print "%10s %s" % (w[0], w[1])
-----------------------------------------------------------------------------
However, when it runs, it gives me more than the active applications:
C:\home\rutt\dev\win32tasks>python tasks.py

There are a few problems with the above output:
1) The first few Windows do not look like they correspond to any task
bar entries at all.
2) "FolderView" is displayed for Windows Explorer open folders; I
would really like to have the name as it exists in the title bar
instead
Does anyone know the appropriate functions to call to narrow down
these window handles to just those that are present in the taskbar?
Thanks,
