Advances the cursor of an in-progress Find session and returns the next matching character index.
Syntax
function FindNext;
Description
Advances the cursor of an in-progress Find session and returns the next matching character index.
Returns -1 when the cursor reaches the end of the document.
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.FindNext;
