#715 Indexing of objects with Items broken

[Braino]

As I read in several places, Objects with the Item() method like should map indexing obj[i] to obj.Item(i).

The problem is: It just does not work for me. After running makepy for the Word 14 Object Library, using

import win32com.client

app = win32com.client.Dispatch("Word.Application")

app.Dialogs.Item(1)  # Succeeds and returns a Library.Dialog Object

app.Dialogs[1]  # Type Error: 'Dialogs' object does not support indexing

I dug deeper and I found that there is indeed no getitem method in the corresponding class created by makepy. The code responsible I identified in the genpy file is:

def WriteClassBody(self, generator):
    ...
    specialItems = {..., "item"=None, ...}
    for name in names:
        ...
        if dispid==pythoncom.DISPID_VALUE:
            lkey = "value"
        ...
        else:
            lkey = name.lower()

        if lkey in specialItems and specialItems[lkey] is None:
            specialItems[lkey] = (entry, ...)

So in principle, it should recognize "item" as special item and remember that it has been there (later there is a section in the code where it checks if "item" was there and adds a getitem method if it was). The problem is that dispid for "item" is actually equal to pythoncom.DISPID_VALUE and therefore the lkey is set to "value" which is not special anymore. You can easily verify that by changing "if dispid==pythoncom.DISPID_VALUE:" to "if dispid==pythoncom.DISPID_VALUE and name.lower() != "item":" and running makepy again; the getitem methods are created and indexing works as it should.
