TInvokeableVariantType.SetProperty Method

Sets the value for any property this System::Variant type supports.

Pascal

function SetProperty(const V: TVarData; const Name: string; const Value: TVarData): Boolean; virtual;

C++

virtual __fastcall Boolean SetProperty(const TVarData V, const AnsiString Name, const TVarData Value);

Description

Override SetProperty to provide the write implementation for the properties of instances of the invokeable System::Variant type. When the application writes to a System::Variant property (Delphi) or calls the System::Variant's Exec method (C++) a call is automatically generated to SetProperty that allows the TInvokeableVariant descendant to implement the call.

Name is the name of the property.

Value is a TVarData record that contains the new property value.

GetProperty returns true if it sets a property value, false if it does not implement the specified property or if the specified property is read-only.

As implemented in TInvokeableVariant, GetProperty always returns false, because it does not implement any properties.
