XMonad.Layout.GridVariants

Description

Two layouts: one is a variant of the Grid layout that allows the desired aspect ratio of windows to be specified. The other is like Tall but places a grid with fixed number of rows and columns in the master area and uses an aspect-ratio-specified layout for the slaves.

# Usage

This module can be used as follows:

    import XMonad.Layout.GridVariants

Then add something like this to your layouts:

    Grid (16/10)

for a 16:10 aspect ratio grid, or

    SplitGrid L 2 3 (2/3) (16/10) (5/100)

for a layout with a 2x3 master grid that uses 2/3 of the screen, and a 16:10 aspect ratio slave grid to its right. The last parameter is again the percentage by which the split between master and slave area changes in response to Expand/Shrink messages.

To be able to change the geometry of the master grid, add something like this to your keybindings:

    ((modm .|. shiftMask, xK_equal), sendMessage $ IncMasterCols 1),
    ((modm .|. shiftMask, xK_minus), sendMessage $ IncMasterCols (-1)),
    ((modm .|. controlMask,  xK_equal), sendMessage $ IncMasterRows 1),
    ((modm .|. controlMask,  xK_minus), sendMessage $ IncMasterRows (-1))

data ChangeMasterGridGeom

The geometry change message understood by the master grid

Constructors

IncMasterRows !Int | Change the number of master rows
IncMasterCols !Int | Change the number of master columns
SetMasterRows !Int | Set the number of master rows to absolute value
SetMasterCols !Int | Set the number of master columns to absolute value
SetMasterFraction !Rational | Set the fraction of the screen used by the master grid

data ChangeGridGeom

data Grid a

Grid layout. The parameter is the desired x:y aspect ratio of windows

Constructors

Grid !Rational |

Instances

LayoutClass Grid a |
Read (Grid a) |
Show (Grid a) |

data TallGrid a

TallGrid layout. Parameters are

- number of master rows
- number of master columns
- portion of screen used for master grid
- x:y aspect ratio of slave windows
- increment for resize messages

This exists mostly because it was introduced in an earlier version. It's a fairly thin wrapper around "SplitGrid L".

Constructors

TallGrid !Int !Int !Rational !Rational !Rational |

Instances

LayoutClass TallGrid a |
Read (TallGrid a) |
Show (TallGrid a) |

data SplitGrid a

SplitGrid layout. Parameters are

- side where the master is
- number of master rows
- number of master columns
- portion of screen used for master grid
- x:y aspect ratio of slave windows
- increment for resize messages

Constructors

SplitGrid Orientation !Int !Int !Rational !Rational !Rational |

Instances

LayoutClass SplitGrid a |
Read (SplitGrid a) |
Show (SplitGrid a) |

data Orientation

Type to specify the side of the screen that holds the master area of a SplitGrid.

Constructors
