Updates: Status: Accepted Owner: vogt.adam Labels: Component-Contrib Priority-Medium Documentation Comment #1 on issue 327 by vogt.adam: Layout.SubLayouts does not work with Layout.Combo http://code.google.com/p/xmonad/issues/detail?id=327 It's a known and difficult issue that not all layouts can be nested within others. As described here, decorated layouts must not be used as the inner layout: http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Layout-SubLayouts.html#3 Instead, use http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Layout-SubLayouts.html#v... (or it's pieces) with a more pure layout, if you want decorations. I believe that this can be type-system enforced by choosing a different type for the inner layout to manage (ex. Int) which is just as Combo does (currently it is Window), but I guess that isn't a substitute for a larger disclaimer (since the errors would suggest to write the missing instance). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
