With XDG support so firmly ingrained now, it's about time we stop hard-coding the configuration path in the docs.

|
-- Lets you constrain the aspect ratio of a floating
|
|
-- window (by, say, holding shift while you resize).
|
|
--
|
|
-- Useful for making a nice circular XClock window.

|
-- $usage
|
|
--
|
|
-- You can use this module with the following in your @xmonad.hs@:
|
|
--
|
|
-- > import qualified XMonad.Actions.ConstrainedResize as Sqr
|
|
--
|
|
-- Then add something like the following to your mouse bindings:
|
|
--
|
|
-- > , ((modm, button3), (\w -> focus w >> Sqr.mouseResizeWindow w False))
|
|
-- > , ((modm .|. shiftMask, button3), (\w -> focus w >> Sqr.mouseResizeWindow w True ))
|
|
--
|
|
-- The line without the shiftMask replaces the standard mouse resize
|
|
-- function call, so it's not completely necessary but seems neater
|
|
-- this way.
|
|
--
|
|
-- For detailed instructions on editing your mouse bindings, see
|
|
-- "XMonad.Doc.Extending#Editing_mouse_bindings".
|
|
|
|
-- | Resize (floating) window with optional aspect ratio constraints.
