Automatic placement of floating windows.

This module provides a ManageHook that automatically places floating windows at appropriate positions on the screen, as well as an X action to manually trigger repositioning.

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

import XMonad.Hooks.Place

and adding placeHook to your manageHook, for example:

main = xmonad $ def { manageHook = placeHook simpleSmart
                                   <> manageHook def }

Note that placeHook should be applied after most other hooks, especially hooks such as doFloat and doShift. Since hooks combined with <> are applied from right to left, this means that placeHook should be the first hook in your chain.

You can also define a key to manually trigger repositioning with placeFocused by adding the following to your keys definition:

, ((modm, xK_w), placeFocused simpleSmart)

Both placeHook and placeFocused take a Placement parameter, which specifies the placement policy to use (smart, under the mouse, fixed position, etc.). See Placement for a list of available policies.

Placement policies determine how windows will be placed by placeFocused and placeHook.

A few examples:

• Basic smart placement

myPlacement = simpleSmart

• Under the mouse (pointer at the top-left corner), but constrained inside of the screen area

myPlacement = inBounds (underMouse (0, 0))

• Smart placement with a preference for putting windows near the center of the screen, and with 16px gaps at the top and bottom of the screen where no window will be placed

myPlacement = withGaps (16,0,16,0) (smart (0.5,0.5))
