[Haskell-cafe] Opening a gtk2hs link in default browser

Hello list, I'm trying to make a clickable link in gtk2hs program. Clicking it should open an url in the default browser. Can I hope to find some portable solution in gtk2hs (it should work in linux and windows) or should I start searching platform specific ones, like /usr/bin/xdg-open or something? Can any examples be found in existing haskell software? Dmitry
