[wxhaskell-users] how to draw one pixel at a time?

[Bernie P. <bj...@cs...>]

Hi wxHaskell people,

I have a little ray-tracer in Haskell. An image is
produced as a stream of pixel intensities.

I want to use wxHaskell to write a display facilty that
will render each pixel as it is generated by the tracer
(so we can see the image being generated pixel by pixel).

My current thoughts are to create a panel and have it
render a bitmap on paint events. The bitmap is implemented
via "varCreate" and so on. The idea is to update the bitmap
and periodically repaint the panel.

Before I commit to this approach I thought it would be wise
to ask for advice in case there is a more idiomatic way
to do it.

Cheers,
Bernie.
