= OnFilterEnd =

== Syntax ==
:{{OnFilterEnd: ((<compound-statement>))}}

== Return ==
:{{((false))}} if the default {{OnFilterEnd}} handler code is to be invoked, or {{((true))}} to prevent the default handler from being invoked (though this latter option is currently ignored in FM 0.4.20).
== Description ==
:The {{OnFilterEnd}} handler is invoked at the end of each filter run, after all calls to the {{((ForEveryTile))}}, {{((ForEveryRow))}}, {{((ForEveryPixel))}}, and {{((R, G, B, A))}} handlers. The {{OnFilterEnd}} handler is a good place to perform any necessary cleanup at the end of a filter run, such as resetting the progress bar indicator.
== Default handler ==
:The default {{OnFilterEnd}} handler calls {{((playSoundWave))(NULL)}} to terminate any wave file that may still be playing.
== Example ==
:You can use the {{OnFilterEnd}} handler to reset the progress bar at the end of a filter run.
<code>
OnFilterEnd:{
    updateProgress(0, 100);  /* reset the progress bar to 0% */
    return false; /* allow the default OnFilterEnd handler to run also */
}
</code>

== Comments ==
:Everyone can add his/her comments about this handler here. Tips for using it are welcome, too.
