</h1><div class="doc"><p>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:
</p><ul><li> The <code><a href="XMonad-Hooks-DynamicBars.html#v:dynStatusBarStartup">dynStatusBarStartup</a></code> hook which initializes the status bars.
</li><li> The <code><a href="XMonad-Hooks-DynamicBars.html#v:dynStatusBarEventHook">dynStatusBarEventHook</a></code> hook which respawns status bars when the
number of screens changes.
</li><li> The <code><a href="XMonad-Hooks-DynamicBars.html#v:multiPP">multiPP</a></code> function which allows for different output based on whether
the screen for the status bar has focus.
</li></ul><p>The hooks take a <code><a href="XMonad-Hooks-DynamicBars.html#t:DynamicStatusBar">DynamicStatusBar</a></code> function which is given the id of the
screen to start up and returns the <code><a href="/usr/share/doc/ghc/html/libraries/base-4.5.0.0/GHC-IO-Handle.html#t:Handle">Handle</a></code> to the pipe to write to. The
<code><a href="XMonad-Hooks-DynamicBars.html#t:DynamicStatusBarCleanup">DynamicStatusBarCleanup</a></code> argument should tear down previous instances. It
is called when the number of screens changes and on startup.
