WSJT-X/UDPExamples/ClientWidget.cpp
Bill Somerville dfe037423f New incoming UDP message to allow external applications to highlight decoded callsigns
UDP  servers can  request that  WSJT-X clients  highlight a  specified
callsign  in  the  Band  Activity  decodes  window.  Either  the  last
occurrence of the  callsign may be highlighted or all  past and future
occurrences can be  highlighted. The latter case  WSJT-X will remember
the  callsign  and  requested  highlighting  options  so  that  future
occurrences can be correctly highlighted.

Either or  both of the text  background color and the  text foreground
color may  be specified. A further  UDP message may be  sent to change
the  persistent color  highlighting  for a  given callsign,  including
reseting persistent highlighting by passing an invalid color value.

Thanks to Alex, VE3NEA, for this contribution.
