PDFium Component Docs

FileName Proprietà

Componente: TPdf · Unità: PDFium

Percorso del PDF da aprire; assegnarlo mentre Active è True ricarica dal nuovo percorso.

Syntax

property FileName;

Description

Path of the PDF to open; assigning while Active reloads from the new path.

Empty string means "no file" — use CreateDocument to start a blank PDF instead.

Wraps the corresponding PDFium API and exposes it as a TPdf instance member so consumers do not have to manage FPDF_DOCUMENT handles directly.

Remarks

Always check Pdf1.Active before calling page-scoped operations; methods that require an open document raise EPdfError otherwise.
Document-edit methods (AddPage / DeletePage / UpdatePage / CreateAnnotation) leave the in-memory document dirty — remember to call SaveToFile to persist.
Class methods (LoadLibrary / UnloadLibrary / GetRecommendedV8Flags) can be called without a TPdf instance.

Example

if Pdf1.Active then
Pdf1.FileName;
