如何使用Python win32com将MS Word中的文本居中

Question

I'm automating the creation of an MS Word document and part of the code utilizes win32com to update the table of contents and the header. The function that does this looks like this:

import win32com.client as win32

def updateHeaderAndTOC(docx_file, headerText):
    word = win32.gencache.EnsureDispatch("Word.Application")
    doc = word.Documents.Open(docx_file)
    word.ActiveDocument.Sections(1)\
        .Headers(win32.constants.wdHeaderFooterPrimary)\
        .Range.Text=headerText
    doc.TablesOfContents(1).Update()
    doc.Close(SaveChanges=True)

This seems to work fine. The problem is that when the header text gets replaced, for some reason, the header gets left justified, instead of being centered the way it was before I changed the header text.

Does somebody know how to

1. Prevent this left justification from happening and/or
2. Center the text again after the text has changed?

Answer 1

Summarizing the results of the comments section, there is no way for win32com to center text in a header. The solution, at least in this case, was to make sure that the formatting in the document was correct on ALL modified lines before trying to modify the text. If your application requires you to modify text, then change the formatting (center, left-justified, etc.) after that header text is changed, win32com can't help...at least today.

Answer 2

Using the the .Paragraphs.Alignment property of the header object as defined below can indeed align the header.

import win32com.client

wrdApp = win32com.client.Dispatch('Word.Application')
doc = wrdApp.Documents.Open(fullFilePathAndName, False)
header = doc.Sections(1).Headers(win32com.client.constants.wdHeaderFooterPrimary).Range
header.Text = "some new header goes here"

#this will align the header content
header.Paragraphs.Alignment = win32com.client.constants.wdAlignParagraphCenter
