Gets a list of symbol objects that match a set of criteria.
The Symbol class encapsulates the attributes that define the appearance and behavior of a specific Symbol page element.
To apply these attributes to a Symbol page element, set the element's SymbolSet and SymbolID properties, as illustrated in the example.
This example shows how to find a matching Symbol and set the properties of a Symbol element to use it.
The Symbol control named 'mySymbol' is set to use the first Symbol Factory symbol in the 'Boilers' category with the word 'flames' in its name.
var symbols = WV.GetMatchingSymbols("Symbol Factory", "Boilers", "flames");
var symbol = symbols[0];
SETP("mySymbol@SymbolSet", symbol.ParentSymbolMap.SymbolSet);
SETP("mySymbol@SymbolID", symbol.SymbolID);
