The parser and renderer is a pre-existing RichTextEdit widget. Add menus and save, open, and print functionality and you are over 90% of the way to a WordPad clone.

Microsoft used to distribute source code for a WordPad sample app with Visual Studio.

Opening and saving as .docx would seem to be the only hard part.

I'm assuming that's not built into the widget or into Windows. Is there an open-source drop-in docx<->rtf library out there?

It’s a pre built widget because Microsoft wrote it for WordPad though.

It’s actually likely to be the opposite. WordPad could be a test application for the RichTextEdit widget.
