ExecuteDocumentLifecycleAction method

Component: TPdf · Unit: PDFium

Runs one document-level lifecycle action on demand

Syntax

function ExecuteDocumentLifecycleAction(Action: TPdfDocumentLifecycleAction; out ErrorMessage: string): Boolean;

Description

ExecuteDocumentLifecycleAction executes one of the document-level actions dlaJavaScript, dlaOpen, dlaWillClose, dlaWillSave, dlaDidSave, dlaWillPrint, or dlaDidPrint and returns True when the action has run

ErrorMessage receives the failure reason when the result is False, for example when LifecycleActionPolicy is lapDisabled or the action is absent

Remarks

With LifecycleActionPolicy = lapAutomatic the component already runs these actions at the matching moments; manual execution is intended for lapManual hosts
dlaJavaScript runs the document-level JavaScript name-tree actions

Log(Err);
