OnlyWhenFocused
The OnlyWhenFocused function is part of the 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.
