Mono: MONO_THEME has no effect under Ubuntu?

Question

I am not entirely sure whether MONO_THEME is supposed to do anything for WinForms applications running under Ubuntu, but I got the impression that I should be able to enable GNOME-like looks by using it. I can't get it to do that though.

Here's what I tried:

export MONO_THEME=visualstyles
mono MyApp.exe

export MONO_THEME=clearlooks
mono MyApp.exe

export MONO_THEME=nice
mono MyApp.exe

But there was exactly zero effect on my application's appearance. I do call Application.EnableVisualStyles() first thing in my code.

How do I enable the themes in Ubuntu?

Answer 1

These were removed several years ago as they were not maintained.

Is there some place that still documents these? If it's somewhere on Mono's site, I would like to remove them.
