[Gtk2hs-users] Subclass a widget.

[Magicloud M. <mag...@gm...>]

Hi,
  I just noticed a mail named "gtk2hs question - derive SettingsWindow
from Window" in gtk2hs ML. As it said, I wonder, is it possible to
subclass a widget? If I use newtype as the mail said, is the "newtype
MyWindow" a widget, so I can use it like "containerAdd myWin"?
