Notification Event

This event notifies the application about an underlying control flow event.

Syntax

type TNotificationEvent = procedure (
  Sender: TObject;
  const EventID: String;
  const EventParam: String
) of Object;

property OnNotification: TNotificationEvent read FOnNotification write FOnNotification;

Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

This component can fire this event with the following EventID values:

DocumentLoadedReports the completion of PDF document processing by the component. Use the event handler to access document-related information, such as page number and document file details. The EventParam value passed with this EventID is empty.
TimestampRequestA timestamp is requested from the custom timestamping authority. This event is only fired if TimestampServer was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to TimestampServer), in base16, that needs to be sent to the TSA.

Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property.

SignatureWidgetPrepareAnother copy of the signature widget needs to be configured. Use the event handler to configure individual widgets when creating multi-widget signatures. The Notification event with this event ID will be fired repeatedly until the LastSignatureWidget configuration property is set to true.

The EventParam value passed with this EventID is empty.
