How to highlight a specified NVDA object by code?

[hwf1324]

I have an add-on (Object Viewer) that uses a GUI to display the structure and information of NVDAObjects. Like Microsoft's Accessibility Insights For Windows, I want the selected NVDAObject to be highlighted on the screen.

Can I do this with the existing NVDAHighlighter related code? It seems that it can only be called through a limited number of Contexts?

I have not tested anything myself.

Have you tried to create a custom class inheriting from HighlightWindow (in NVDAHighlighter.py) and to redefine the _paint method?
