Description
This component provides a TAKE, UNDO, and DESELECT button set for use in a single layer matrix crosspoint selection panel. The component has several parameters
that can be set at design time, and two parameters that are set at runtime. The matrix to be controlled is set by entering a name in the host script control
"Instances" field. The source crosspoint and destination crosspoint are sent via either another script or, more usually, via the connections engine.
The source numeric ID is sent as parameter "sourceID" and the destination ID is sent as parameter "destID". Using a BNCS "Name Grid" or "Dest Grid" control,
set to report on Index change enables the connection engine to pass the index values. Index values less than 1 count as deslection indication from the
source or destination.
When the user presses the "Deselect" button the component sends a "deselect=-1" to the host. The value of -1 can be directed to the highlight function of
the "Name Grid" or "Dest Grid" causing them to deselect any current active selection.
