XMonad.Util.StringProp

Description

Internal utility functions for storing Strings with the root window.

Used for global state like IORefs with string keys, but more latency, persistent between xmonad restarts.

Synopsis

- type StringProp = String
- getStringProp :: MonadIO m => Display -> StringProp -> m (Maybe [Char])
- setStringProp :: MonadIO m => Display -> StringProp -> [Char] -> m ()
- getStringListProp :: MonadIO m => Display -> StringProp -> m [String]
- setStringListProp :: MonadIO m => Display -> StringProp -> [String] -> m ()

# Documentation

type StringProp = String #

getStringProp :: MonadIO m => Display -> StringProp -> m (Maybe [Char]) #

Get the name of a string property and returns it as a `Maybe`.

setStringProp :: MonadIO m => Display -> StringProp -> [Char] -> m () #

Set the value of a string property.

getStringListProp :: MonadIO m => Display -> StringProp -> m [String] #

Given a property name, returns its contents as a list. It uses the empty list as default value.

setStringListProp :: MonadIO m => Display -> StringProp -> [String] -> m () #

Given a property name and a list, sets the value of this property with the list given as argument.
