XMonad.Hooks.ManageDocks

This module provides tools to automatically manage dock type programs, such as gnome-panel, kicker, dzen, and xmobar.

Usage

To use this module, add the following import to ~/.xmonad/xmonad.hs:

 import XMonad.Hooks.ManageDocks

The first component is a ManageHook which recognizes these windows and de-manages them, so that xmonad does not try to tile them. To enable it:

 manageHook = ... <+> manageDocks

The second component is a layout modifier that prevents windows from overlapping these dock windows. It is intended to replace xmonad's so-called "gap" support. First, you must add it to your list of layouts:

 layoutHook = avoidStruts (tall ||| mirror tall ||| ...)
                   where  tall = Tall 1 (3/100) (1/2)

The third component is an event hook that causes new docks to appear immediately, instead of waiting for the next focus change.

 handleEventHook = ... <+> docksEventHook

AvoidStruts also supports toggling the dock gaps; add a keybinding similar to:

 ,((modm, xK_b     ), sendMessage ToggleStruts)

If you have multiple docks, you can toggle their gaps individually. For example, to toggle only the top gap:

 ,((modm .|. controlMask, xK_t), sendMessage $ ToggleStrut U)

Similarly, you can use D, L, and R to individually toggle gaps on the bottom, left, or right.

If you want certain docks to be avoided but others to be covered by default, you can manually specify the sides of the screen on which docks should be avoided, using avoidStrutsOn. For example:

 layoutHook = avoidStrutsOn [U,L] (tall ||| mirror tall ||| ...)

Important note: if you are switching from manual gaps (defaultGaps in your config) to avoidStruts (recommended, since manual gaps will probably be phased out soon), be sure to switch off all your gaps (with mod-b) before reloading your config with avoidStruts! Toggling struts with a ToggleStruts message will not work unless your gaps are set to zero.

For detailed instructions on editing your key bindings, see XMonad.Doc.Extending.

manageDocks :: ManageHook

Detects if the given window is of type DOCK and if so, reveals it, but does not manage it. If the window has the STRUT property set, adjust the gap accordingly.

checkDock :: Query Bool

Checks if a window is a DOCK or DESKTOP window

data AvoidStruts a

Instances

LayoutModifier AvoidStruts a

Read (AvoidStruts a)

Show (AvoidStruts a)

avoidStruts :: LayoutClass l a => l a -> ModifiedLayout AvoidStruts l a

Adjust layout automagically: don't cover up any docks, status bars, etc.

avoidStrutsOn :: LayoutClass l a => [Direction2D] -> l a -> ModifiedLayout AvoidStruts l a

Adjust layout automagically: don't cover up docks, status bars, etc. on the indicated sides of the screen. Valid sides are U (top), D (bottom), R (right), or L (left).

docksEventHook :: Event -> X All

Whenever a new dock appears, refresh the layout immediately to avoid the new dock.

data ToggleStruts

Message type which can be sent to an AvoidStruts layout modifier to alter its behavior.

data SetStruts

SetStruts is a message constructor used to set or unset specific struts, regardless of whether or not the struts were originally set. Here are some example bindings:

Show all gaps:

   ,((modm .|. shiftMask  ,xK_b),sendMessage $ SetStruts [minBound .. maxBound] [])

Hide all gaps:

   ,((modm .|. controlMask,xK_b),sendMessage $ SetStruts [] [minBound .. maxBound])

Show only upper and left gaps:

   ,((modm .|. controlMask .|. shiftMask,xK_b),sendMessage $ SetStruts [U,L] [minBound .. maxBound])

Hide the bottom keeping whatever the other values were:

   ,((modm .|. controlMask .|. shiftMask,xK_g),sendMessage $ SetStruts [] [D])

Goes through the list of windows and find the gap so that all STRUT settings are satisfied.
