This topic covers the implementation details of TBtnEditProperty.
Scope: cBtnEditProperty.pas; class derived from TSL_Property. Prepared from the curated implementation supplied for this review on 2 October 2026.
This supporting base class reads Version when present. It inherits the property envelope writer. Its constructor creates the text-blob list, sets Version=0 and clears the modified flag. No local SaveToXML implementation is supplied; follow TSL_Property for the inherited envelope.
Notation and shared helper rules: Reading this reference.
No literal rec_type value is emitted directly by the selected routines. A property envelope, an inherited writer or a delegated record can supply its identifying attributes.
Inherited implementation: TSL_Property. Follow it when the ordered behavior invokes inherited methods; inherited fields are not repeated as locally owned fields.
Exact XML fields and attributes
The paths below start at this record or property node. A slash identifies a child element; @ identifies an attribute. Curly braces mark a variable index or expression, not literal XML text. Initial values describe initialization; they do not establish what an omitted individual element does. The Implementation toggle below contains the supplied routines for exact branch order and conversions.
Version
XML representation: The text of the Version element.
Initial value: 0 (TBtnEditProperty.Create).
Reading: Converts the stored text to a number and assigns it to Version when the record node exists.
Export: No corresponding write is implemented locally. This can be a compatibility input or a field handled elsewhere.

This routine also calls inherited Create. See Implementation for their order and any conditional calls.
Storage declarations relevant to interpretation
These are in-memory member and property types, not a list of mandatory XML children. They retain array bounds, fixed buffers and selector types. The field reference above defines what is actually serialized.

The Implementation toggle contains only TBtnEditProperty methods. Initializers and helpers belonging to other types are identified separately below. Shared XML-helper limitations are explained in Reading this reference.
