Qt QPlainTextEdit background

Question

I want to change the background color of a QPlainTextEdit, how do I do this?

Answer 1

Slightly confusingly they call it role rather than colour/color.

hint - if you can't find a function for a particular control, click on show inherited members - most general settings are in qWidget which is the basis for eveything drawn on screen.
