When tiling the module attempts to tile windows on the current screen subject to certain constraints. Horizontal or vertical tiling is performed so that each window does not overlap another, and by default each window is resized to its nearest resize increment (note sometimes some space might appear between tiled windows -- this is why).

When cascading the module attempts to cascade windows on the current screen subject to certain constraints. Layering is performed so consecutive windows will have their window titles performed so consecutive windows will have their window titles visible underneath the previous.

FvwmRearrange -tile -h 10 10 90 90

or

FvwmRearrange -cascade -resize 10 2 80 70

The first invocation will horizontally tile windows with a bounding box which starts at 10 by 10 percent into and down the screen and ends at 90 by 90 percent into and down the screen.

The second invocation will cascade windows starting 10 by 2 percent into and down the screen. Windows will be constrained to 80 by 70 percent of the screen dimensions. Since the resize is also specified, windows will be resized to the given constrained width and height.

FvwmRearrange can be called as FvwmTile or FvwmCascade. This is equivalent to providing the -tile or -cascade option. This form is obsolete and supplied for backwards compatibility only.

Command-line arguments passed to FvwmRearrange are described here.

-a

Causes all window styles to be affected, even ones with the WindowListSkip style.

-cascade

Cascade windows. This argument must be the first on the command line. This is the default.

-desk

Causes all windows on the desk to be cascaded/tiled instead of the current screen only.

-flatx

Inhibits border width increment. Only used when cascading.

-flaty

Inhibits border height increment. Only used when cascading.

-h

Tiles horizontally (default is to tile vertically). Used for tiling only.

-incx arg

Specifies a horizontal increment which is successively added to cascaded windows. arg is a percentage of screen width, or pixel value if a p is suffixed. Default is zero. Used only for cascading.

-incy arg

Specifies a vertical increment which is successively added to cascaded windows. arg is a percentage of screen height, or pixel value if a p is suffixed. Default is zero. Used only for cascading.

-m

Causes maximized windows to also be affected (implied by -all).

-mn arg

Tiles up to arg windows in tile direction. If more windows exist, a new direction row or column is created (in effect, a matrix is created). Used only when tiling windows.

-noraise

Inhibits window raising, leaving the depth ordering intact.

-noresize

Inhibits window resizing, leaving window sizes intact. This is the default when cascading windows.

-nostretch

If tiling: inhibits window growth to fit tile. Windows are shrunk to fit the tile but not expanded.

If cascading: inhibits window expansion when using the -resize option. Windows will only shrink to fit the maximal width and height (if given).

-r

Reverses the window sequence.

-resize

Forces all windows to resize to the constrained width and height (if given). This is the default when tiling windows.

-s

Causes sticky windows to also be affected (implied by -all).

-t

Causes transient windows to also be affected (implied by -all).

-tile

Tile windows. This argument must be the first on the command line.

-u

Causes untitled windows to also be affected (implied by -all).

Causes untitled windows to also be affected (implied by -all).

Up to four numbers can be placed on the command line that are not switches. The first pair specify an x and y offset to start the first window (default is 0, 0). The meaning of the second pair depends on operation mode:

When tiling windows it specifies an absolute coordinate reference denoting the lower right bounding box for tiling.

When cascading it specifies a maximal width and height for the layered windows. If an affected window exceeds either this width or height, it is resized to the maximal width or height.

If any number is suffixed with the letter p, then it is taken to be a pixel value, otherwise it is interpreted as a screen percentage. Specifying zero for any parameter is equivalent to not specifying it.
