====OnlyWhenFocused===

The **OnlyWhenFocused** function is part of the [[HMITTPanel|HMITTPanel]] class used to connect to live ARDI data.

It sets up event handlers so that the feed of live data stops when a HTML page or SVG file is in the background (ie. not the active tab in your web browser).

This helps avoid congestion and issues when tabs have been closed for an extended period and new data floods in.

===Parameters===

None

===Notes===

This function is automatically called as part of Connect in newer versions of the library and is mostly present for backwards compatibility.
