TdxPDFViewerRotateCounterClockwise Class

An action object corresponding to the RotateCounterclockwise command provided by the PDF Viewer control.

Declaration

delphi

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.
