FindPrevious metódus - TPdf

Egy találattal visszafelé lépteti a Find kurzort

Szintaxis

function FindPrevious;

Reverses the Find cursor by one match.

Use to implement Shift+F3 / "Find Previous" actions.

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

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.

if Pdf1.Active then
Pdf1.FindPrevious;
