Event Handling und Schnittstellen

Die einzelnen Komponenten arbeiten mit @Input und @Outputs, wie bei Angular üblich. Über diese kann auf Events des Viewers reagiert werden, zum Beispiel wenn das Dokument oder die aktive Seite gewechselt wurde.

Aktuell kann auf die folgenden Events reagiert werden:

Name	Description
currentPageIndexChange	Will emit whenever the viewer's current page changes.
zoomFactorChange	Will emit whenever the viewer's zoom factor changes.
pageCountChange	Will emit whenever the viewer's amount of loaded pages changes. During a document load, this will emit several times, usually once per page.
viewerInitialized	Will emit once per component once the GWT viewer has been attached.
documentChanged	Will emit whenever the viewer's document model changes. This usually happens once the first page of the physical document has been loaded.
passwordRequired	Will emit when a password-protected PDF document is loaded.
sourceChanged	Will emit whenever the viewer's source changes.
pageLayoutChanged	Will emit whenever the viewer's PageLayout changes.
annotationsChanged	Will emit whenever the viewer's list of annotations changes.
pageSegmentsChanged	Will emit whenever page segments in the currently displayed document have been added, removed or modified.
renderEvent	Will emit whenever the viewer's render controls change, e.g. zoom and page rotation.
