An action object corresponding to the RotateCounterclockwise command provided by the PDF Viewer control.
Declaration
TdxPDFViewerRotateCounterClockwise = class(
TdxPDFViewerCustomAction
)Remarks
This class does not introduce any new public members. Execute a TdxPDFViewerRotateCounterClockwise action object to rotate the current PDF document view counterclockwise by 90 degrees. Alternatively, you can press the Ctrl+Shift+Minus Sign(-) key combination or click the Rotate Counterclockwise item in the control’s context menu to achieve the same end.
When executed, a RotateCounterclockwise command internally calls the PDF Viewer control’s RotateCounterClockwise procedure.
UI elements linked to a TdxPDFViewerRotateCounterClockwise action object are enabled only if the PDF Viewer control currently displays a document (that is, the control’s IsDocumentLoaded function returns True).
For detailed information on the core functionality of PDF Viewer action objects, refer to the TdxPDFViewerCustomAction class description.
