XMonad.Hooks.DynamicBars

Contents

- Usage

Description

Manage per-screen status bars.

Synopsis

- type DynamicStatusBar = ScreenId -> IO Handle
- type DynamicStatusBarCleanup = IO ()
- dynStatusBarStartup :: DynamicStatusBar -> DynamicStatusBarCleanup -> X ()
- dynStatusBarEventHook :: DynamicStatusBar -> DynamicStatusBarCleanup -> Event -> X All
- multiPP :: PP -> PP -> X ()

# Usage

Provides a few helper functions to manage per-screen status bars while dynamically responding to screen changes. A startup action, event hook, and a way to separate PP styles based on the screen's focus are provided:

- The `dynStatusBarStartup` hook which initializes the status bars.
- The `dynStatusBarEventHook` hook which respawns status bars when the number of screens changes.
- The `multiPP` function which allows for different output based on whether the screen for the status bar has focus.

The hooks take a `DynamicStatusBar` function which is given the id of the screen to start up and returns the `Handle` to the pipe to write to. The `DynamicStatusBarCleanup` argument should tear down previous instances. It is called when the number of screens changes and on startup.

type DynamicStatusBar = ScreenId -> IO Handle

dynStatusBarEventHook :: DynamicStatusBar -> DynamicStatusBarCleanup -> Event -> X All
