Not so bad:) With X.L.WN, if I understand it correctly, it wouldn't. With X.A.WN, it might. > I forgot to mention the XMonad.Actions.WindowNavigation.

The usage of X.A.WN is different, see the documentation. Regards, -- Tomáš Janoušek, a.k.a. Liskni_si, http://work.lisk.in/

Inconsistencies in `instance Monoid ManageHook'
by Adam Vogt 03 Aug '10

03 Aug '10

Hi, The behavior of instance Monoid ManageHook is unnecessarily complicated. Perhaps the following example can convince you If a and b are defined with some arbitrary a', b' manipulations of the WindowSet like > a :: ManageHook > a = do > liftIO (putStrLn "a") > doF a' Then > a <+> b can be written as > do > liftIO (putStrLn "a") > liftIO (putStrLn "b") > doF (a' . b') Side effects take place from left-to-right. The WindowSet is threaded from right-to-left through the functions (which could be produced as a result of those side effects). Possible correction: 1. Change ManageHook > type ManageHook = Query (Dual (Endo WindowSet)) For: All Monoid instances involved with XMonad would be left-to-right (Data.Map.Map prefering values on the left for duplicate keys doesn't fitting any direction in my opinion) Against: Will break quite a few configurations 2. Change instance Monoid (Query a) > instance (Monoid a) => Monoid (Query a) where > mappend = flip (liftM2 (flip mappend)) For: Less code is likely to be broken by flipping the order that IO is run, since much fewer ManageHooks seem to involve liftX or liftIO for changing things that could be read later Against: Left-to-right remains a special case for ManageHook How much would you value consistency when using (<+>) = mappend with nearly all fields in XConfig? Are any current or reasonable uses of ManageHook be impossible if one of the composition orders were changed for consistency? -- Adam

WindowNavigation and Spacing Issue
by David Hrachovy 02 Aug '10

Hello everyone! when using WindowNavigation and Spacing together, the window navigation doesn't work. If the 'spacing 2' is removed the navigation works. I like both the features. Can you please help me set up window spacing and easy window navigation? Try out this minimal example to see the issue - NOTE: you have to spawn at least three terminals to be able to see it): import XMonad import Data.Monoid import System.Exit import qualified XMonad.StackSet as W import qualified Data.Map as M import XMonad.Layout.WindowNavigation import XMonad.Layout.Spacing myKeys conf@(XConfig {XMonad.modMask = modm}) = M.fromList $ [ ((modm .|. shiftMask, xK_Return), spawn $ XMonad.terminal conf) -- Quit xmonad , ((modm .|. shiftMask, xK_q ), io (exitWith ExitSuccess)) -- Restart xmonad , ((modm , xK_q ), spawn "xmonad --recompile; xmonad --restart") -- WindowNavigation , ((modm, xK_l), sendMessage $ Go R) , ((modm, xK_h ), sendMessage $ Go L) , ((modm, xK_k ), sendMessage $ Go U) , ((modm, xK_j ), sendMessage $ Go D) ] myLayout = windowNavigation $ spacing 2 tiled where tiled = Tall nmaster delta ratio nmaster = 1 ratio = 1/2 delta = 3/100 main = xmonad defaultConfig { terminal = "xterm", keys = myKeys, layoutHook = myLayout } I am running xmonad 0.9.1. Thank you David H.

Issue 349 in xmonad: Chromium gives BadWindow (invalid Window parameter)
by codesite-noreply＠google.com 02 Aug '10

Status: New Owner: ---- New issue 349 by ninternity: Chromium gives BadWindow (invalid Window parameter) http://code.google.com/p/xmonad/issues/detail?id=349 What steps will reproduce the problem? 1. Using the Chromium package, "chromium-browser" What is the expected output? A running chromium instance. What do you see instead? The program 'chromium-browser' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 116 error_code 3 request_code 20 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) What version of the product are you using? On what operating system? xmonad 0.9, installed from Hackage Xubuntu 9.10 Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". Please provide any additional information below. Error does not happen when using xfce + Xubuntu 9.10, nor in xmonad 0.9 + Xubuntu 9.04. Chromium version: 4.0.267.0~svn20091208r34059-0ubuntu1~ucd1~karmic Attachments: xmonad.hs 1.6 KB xmonad_recompile_out 238 bytes -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
