I'm trying to create a program that will process files dragged into

when something is dragged over the window. I've created an object that
implements the IDropTarget interface, but it seems the value returned
by its DragEnter method is ignored by Windows. No matter what value it
returns, I always get a "create shortcut" cursor when something is
dragged over the window.
This is a segment of my code which works ok:
<... code snippet ...>
def DragEnter (self, data_object, key_state, point, effect):
ur"""Query the data block for a drag action which is over the dialog.
If we can handle it, indicate that we're ready to accept a drop from
this data.
"""
try:
data_object.QueryGetData (self._data_format)
except pywintypes.error:
return shellcon.DROPEFFECT_NONE
else:
return shellcon.DROPEFFECT_COPY
<... code snippet ...>
The whole code's here if you want:
https://winsys.googlecode.com/svn/trunk/winsys/dialogs.py
It looks as though you're returning an OK *and* the effect
which isn't how the thing is implemented via the pywin32
wrappers.
