Interface PdfDocumentChangeHandler

public interface PdfDocumentChangeHandler

This interface defines run-time events for loading and closing a document.

In the event handler methods, user classes will be able do some processing on the newly loaded document. For example, a PDF viewer application will be able to display the title of the newly loaded document in the title bar by implementing the onLoad() event. Similarly, just before a document is closed, the user application will be able to remove any information related to the document on the end-user application interface.
