[python-win32] Hook windows messages with python

[Christoph Buck]

Hi!

I'm trying to set a message hook with python to catch WM_DROPFILES.
The guiframework is Tkinter.
Here a code snippet:

 > hwnd = eval(self.wm_frame())
 > win32gui.DragAcceptFiles(hwnd,1)
 > wnd = win32ui.CreateWindowFromHandle(hwnd)
 > wnd.HookMessage(self.test,w32con.WM_DROPFILES)

 > def test(self):
 >    print "blala"

The DragAcceptFiles-Call seems to be alright. When i drag a file over
the gui there is this drag-and-drop icon. But the problem is, that the
callback-function (test) is never executed.
I also try different messages like Mousemove or Buttondown. So i think
there is a problem with the HookMessage function.
I read that you must compile Python with PYWIN_WITH_WINDOWPROC option
enabled. Is this the problem?

Can someone give me a short working code to hook a message so i can try
it on my workstation?

Thx in advance!
