RichEdit paint background

Question

I know how to change the background on a single row in a TRichEdit control. But because this is applied to the selected text only, I can't set the background color of the whole line (client left to client right), only to the text part.

I tried to use the WM_ERASEBKGND message, but it doesn't work because a RichEdit control is painting the background in its WM_PAINT handler.

I also tried to set the brush to bsClear before calling the WM_PAINT handler, but it didn't work either.

Is it possible at all to have a custom drawn background?

Answer 1

You'll be able to do so by using the EM_SETBKGNDCOLOR message.
