Example:
A shape on a Mimic is animated to represent an analog point. A ToolTip is required for the shape—the ToolTip is to provide the High High and High alarm levels for the point. To achieve this, the shape's TooltipText property is animated by the following expression:
'Alarm Limits ' + CHR( 10 ) + ".AI.HighHighDesc" + ': ' + STR(".AI.HighHighLimit" ) + CHR( 10 ) + ".AI.HighDesc" + ': ' + STR(".AI.HighLimit" )
Where:
'Alarm Limits' is a text string that is followed by a line break (represented by CHR( 10 ) ).
"AI.HighHighDesc" is the High High Description value of the "AI" point.
"AI.HighHighLimit" is the High High Limit value of the "AI" point. This is followed by another line break (CHR(10)).
"AI.HighDesc" is the High Description value of the "AI" point.
"AI.HighLimit" is the High Limit value of the "AI" point.
The STR function is also required.
The ToolTip for the shape displays the following information:
