Description

TPropInfo is a record of component property type information.

TPropInfo is principally used to hold the results of a call to GetPropInfo. It provides meta details about a component property as part of Delphi's RTTI (Run Time Type Information) mechanism, giving run time component property processing. This allows for more generalised component handling that avoids excessive hard coded values.

The TPropInfo fields have the foillowing meanings :

Field	Meaning
PropType	Points to a data structure that gives information about the property type.
GetProc	Method pointer for the method that gets the component property value.
SetProc	Method pointer for the method that sets the component property value.
Index	The index of the property. It is used as a parameter to the GetProc and SetProc methods on indexed properties.
Default	The default value of the property.
NameIndex	The offset into the Name field where the property's name starts.
Name	The qualified property name.
