Why not simply do this in the OnDropFiles() function,
i.e.
<code>
class FileDropTarget(wx.FileDropTarget):
    def __init__(self, obj):
        wx.FileDropTarget.__init__(self)
        self.obj = obj

    def OnDropFiles(self, x, y, filenames):
        [self.obj.Append(f) for f in filenames]
        print "component", self.obj.name, "received files", filenames  
--- THIS
   
</code>

I don't.
However, I think the event mechanism for dropping is different from the 
usual one. If you could simply bind to EVT_DROP_FILES, then I think 
there'd be no need for the SetDropTarget complexity, would there?

However, I do know for sure that the above change works and prints out 
the name of the component on which they've been dropped, and  (just the 
new) file names on a drop event, so it can be used even if you have 
multiple drop targets.
