[python-win32] Creating python com objects

[Alex Denham]

I haven't checked anything from wxWidgets and i don't intend to (yet).
I have found many functions that appear to help with dragging and dropping in Windows, but practically no documentation to go with.
Piecing bits together from google, msdn, PyWin32 documentation, Python Programming on Win32, has just left me confused and unsure about which is the wright way.

RegisterDragDrop, aparently (from my understanding) registers a window to allow dragging and dropping, first argument is a window id, the second argument is a 'dropTarget'
The documentation i have found follows:  (note how helpful it is)

RegisterDragDrop(hwnd, dropTarget)
Registers the specified window as one that can be the target of an OLE 
drag-and-drop operation and specifies the PyIDropTarget instance to use for drop operations.

Parameters

hwnd : long



dropTarget : PyIDropTarget
documentation for PyIDropTarget:
there is none.

I'm trying to create this 'dropTarget' and pass it to the RegisterDragDrop function however, i can't do that, because it seems to want a COM object, and my attempts at making a com object don't seem to be good enough for RegisterDragDrop.

Thanks
Alex

I might be greatly misinterpreting what you're trying to do here, 
but RegisterDragDrop registers a window, not a com object.  The drop target 
instance would be associating the target with that particular 
window.   Have you checked out wxDropTarget?

Hi,

Anybody happen to know how to go about 
creating a COM object that RegisterDragDrop() will actually accept?

print 
dropTarget
<COMObject 
Python.PyIDropTarget>

pythoncom.RegisterDragDrop(_id, 
dropTarget)

Traceback (most recent call last):
  File 
"C:\Python25\DragAndDrop.py", line 82, in <module>
    
main()
  File "C:\Python25\DragAndDrop.py", line 41, in 
main
    pythoncom.RegisterDragDrop(_id, 
dropTarget)
ValueError: argument is not a COM object

Any help 
appreciated,

Thanks
Alex
