Remarks

This class does not introduce any new public members. Executing a TdxPDFViewerGoToPrevPage action object selects the page preceding the currently selected page. Technically, this action object calls the PDF Viewer’s GoToPrevPage procedure.

UI elements linked to a TdxPDFViewerGoToPrevPage action object are enabled only if the following conditions are met:

The PDF Viewer control displays a document (i.e., the control’s IsDocumentLoaded function returns True).
The loaded document has more than a single page.
Any page other than the first is currently selected (i.e., the PDF Viewer control’s CurrentPageIndex property value exceeds 0).
