XMonad.Actions.FloatSnap

Contents

Description

Move and resize floating windows using other windows and the edge of the screen as guidelines.

Synopsis

Usage

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

    import XMonad.Actions.FloatSnap

Then add appropriate key bindings, for example:

        , ((modm,               xK_Left),  withFocused $ snapMove L Nothing)
        , ((modm,               xK_Right), withFocused $ snapMove R Nothing)
        , ((modm,               xK_Up),    withFocused $ snapMove U Nothing)
        , ((modm,               xK_Down),  withFocused $ snapMove D Nothing)
        , ((modm .|. shiftMask, xK_Left),  withFocused $ snapShrink R Nothing)
        , ((modm .|. shiftMask, xK_Right), withFocused $ snapGrow R Nothing)
        , ((modm .|. shiftMask, xK_Up),    withFocused $ snapShrink D Nothing)
        , ((modm .|. shiftMask, xK_Down),  withFocused $ snapGrow D Nothing)

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

And possibly add an appropriate mouse binding, for example:

        , ((modm,               button1), (\w -> focus w >> mouseMoveWindow w >> snapMagicMove (Just 50) (Just 50) w))
        , ((modm .|. shiftMask, button1), (\w -> focus w >> mouseMoveWindow w >> snapMagicResize [L,R,U,D] (Just 50) (Just 50) w))
        , ((modm,               button3), (\w -> focus w >> mouseResizeWindow w >> snapMagicResize [R,D] (Just 50) (Just 50) w))

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

Using these mouse bindings, it will not snap while moving, but allow you to click the window once after it has been moved or resized to snap it into place. Note that the order in which the commands are applied in the mouse bindings are important.

Interesting values for the distance to look for window in the orthogonal axis are Nothing (to snap against every window), Just 0 (to only snap against windows that we should collide with geometrically while moving) and Just 1 (to also snap against windows we brush against).

For snapMagicMove, snapMagicResize and snapMagicMouseResize, try instead setting it to the same as the maximum snapping distance.

When a value is specified it can be geometrically conceived as adding a border with the specified width around the window and then checking which windows it should collide with.

Constructors

R

L

snapMoveSource

Arguments

:: Direction2D

What direction to move the window in.

-> Maybe Int

The distance in the orthogonal axis to look for windows to snap against. Use Nothing to snap against every window.

-> Window

The window to move.

-> X () 

Move a window in the specified direction until it snaps against another window or the edge of the screen.

snapGrowSource

Arguments

:: Direction2D

What edge of the window to grow.

-> Maybe Int

The distance in the orthogonal axis to look for windows to snap against. Use Nothing to snap against every window.

-> Window

The window to grow.

-> X () 

Grow the specified edge of a window until it snaps against another window or the edge of the screen.

snapShrinkSource

Arguments

:: Direction2D

What edge of the window to shrink.

-> Maybe Int

The distance in the orthogonal axis to look for windows to snap against. Use Nothing to snap against every window.

-> Window

The window to shrink.

-> X () 

Shrink the specified edge of a window until it snaps against another window or the edge of the screen.

snapMagicMoveSource

Arguments

:: Maybe Int

The distance in the orthogonal axis to look for windows to snap against. Use Nothing to snap against every window.

-> Maybe Int

The maximum distance to snap. Use Nothing to not impose any boundary.

-> Window

The window to move.

-> X () 

Move a window by both axises in any direction to snap against the closest part of other windows or the edge of the screen.

snapMagicResizeSource

Arguments

:: [Direction2D]

The edges to snap.

-> Maybe Int

The distance in the orthogonal axis to look for windows to snap against. Use Nothing to snap against every window.

-> Maybe Int

The maximum distance to snap. Use Nothing to not impose any boundary.

-> Window

The window to move and resize.

-> X () 

Resize the window by each edge independently to snap against the closest part of other windows or the edge of the screen.

snapMagicMouseResizeSource

Arguments

:: Rational

How big the middle snap area of each axis should be.

-> Maybe Int

The distance in the orthogonal axis to look for windows to snap against. Use Nothing to snap against every window.

-> Maybe Int

The maximum distance to snap. Use Nothing to not impose any boundary.

-> Window

The window to move and resize.

-> X () 

Resize the window by each edge independently to snap against the closest part of other windows or the edge of the screen. Use the location of the mouse over the window to decide which edges to snap. In corners, the two adjoining edges will be snapped, along the middle of an edge only that edge will be snapped. In the center of the window all edges will snap. Intended to be used together with XMonad.Actions.FlexibleResize or XMonad.Actions.FlexibleManipulate.
