Returns the class type of a component property that is an object type.
TypInfo
GetObjectPropClass utilises Delphi's RTTI (Run Time Type Information) to return the class type of a component's property where that property is an object.
In one form of this function, the object Instance's property is defined by a PropInfo record. GetPropInfo and GetPropList can be used to obtain such a record.
In the other form of this function, the name of the property, PropName, is explicitly given.
In both forms of the function, the class type of the property object value is returned.
The intrinsic value of this function is to allow retrieval of component properties without the need to hard code the property name. This allows mass visual component processing at run time.
Use GetPropValue to retrieve a property value where the type is unknown - it is returned in a Variant type.
