XMonad.Layout.LayoutHints

Make layouts respect size hints.

usage

You can use this module with the following in your ~/.xmonad/xmonad.hs:

import XMonad.Layout.LayoutHints

Then edit your layoutHook by adding the layoutHints layout modifier to some layout:

myLayout = layoutHints (Tall 1 (3/100) (1/2))  ||| Full ||| etc..
main = xmonad defaultConfig { layoutHook = myLayout }

Or, to center the adapted window in its available area:

myLayout = layoutHintsWithPlacement (0.5, 0.5) (Tall 1 (3/100) (1/2))
                  ||| Full ||| etc..

Or, to make a reasonable attempt to eliminate gaps between windows:

myLayout = layoutHintsToCenter (Tall 1 (3/100) (1/2))

For more detailed instructions on editing the layoutHook see:

XMonad.Doc.Extending

To make XMonad reflect changes in window hints immediately, add hintsEventHook to your handleEventHook.

myHandleEventHook = hintsEventHook <+> ...

main = xmonad defaultConfig { handleEventHook = myHandleEventHook
                            , ... }

layoutHints :: LayoutClass l a => l a -> ModifiedLayout LayoutHints l a

layoutHintsWithPlacement :: LayoutClass l a => (Double, Double) -> l a -> ModifiedLayout LayoutHints l a

layoutHintsWithPlacement (rx, ry) layout will adapt the sizes of a layout's windows according to their size hints, and position them inside their originally assigned area according to the rx and ry parameters. (0, 0) places the window at the top left, (1, 0) at the top right, (0.5, 0.5) at the center, etc.

layoutHintsToCenter :: LayoutClass l a => l a -> ModifiedLayout LayoutHintsToCenter l a

layoutHintsToCenter layout applies hints, sliding the window to the center of the screen and expanding its neighbors to fill the gaps. Windows are never expanded in a way that increases overlap.

layoutHintsToCenter only makes one pass at resizing the neighbors of hinted windows, so with some layouts (ex. the arrangement with two Mirror Tall stacked vertically), layoutHintsToCenter may leave some gaps. Simple layouts like Tall are unaffected.
