The FAQ mentions you can set focusFollowsMouse to false to disable it completely, but I'd like to disable focus following the mouse only when moving the mouse over a particular window (the pointer going over any other window should still cause that window to get focus). Is there an easy way to do that?

Maybe "followOnlyIf" from http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Layout-MagicFocus.html will help you.

Slightly OT: I was reading the original question and thought "well, this is really something esoteric that probably requires a homebrewed solution". So it turns out I was wrong. Wow, I'm impressed! N.

I'm close, but I only know how to get the opposite of the functionality I want. The code below prevents focus on all windows except those with the name "Call with " but I actually want it to focus on any window except that one. But ManageHook doesn't define a negation operator, just "=?", so I'm not sure how to do it (pardon my lack of haskell literacy ;p). Also, what I really want to do is match the regex ".*Call with.*" but I figured I'd try to get it working with an exact name first. In general, when you have a Query Bool, is there a way to get the Bool out of it so you can do normal operations? I know this is related to how monads work, but I don't really understand xmonad's architecture yet. -- Focus follows mouse is annoying for skype followEventHook event = followOnlyIf (notSkype) event where notSkype = runQuery ((stringProperty "WM_NAME") =? "Call with ") (ev_window event) On Mon, Dec 5, 2011 at 1:57 PM, Brent Yorgey wrote:

I don't think it's that esoteric. I use followOnlyIf for the "inverse" situation: I have focusFollowsMouse off by default, except for Gimp windows where it is enabled.

As mentioned in the other reply fmap lifts functions. So to match "Call with" anywhere inside WM_NAME, you can import Data.List to use its isInfixOf test (there are also isPrefixOf and isSuffixOf). Also in ManageHook, `title' is provided for matching WM_NAME. So all in all I think you're after: runQuery (fmap (not . ("Call with" `isInfixOf`)) title) -- wmw
