Hooking windowsmessages with python
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! -- http://mail.python.org/mailman/listinfo/python-list

If no one has a simpler way, I can help you build a DLL to do it, and call it from Python. -- http://mail.python.org/mailman/listinfo/python-list

I recommend re-posting to the PyWin32 mailing list where the creators of this package lurk. They'll probably be able to give you some advice: http://mail.python.org/mailman/listinfo/python-win32 Mike -- http://mail.python.org/mailman/listinfo/python-list
