TRvSystem. OnPreviewSetup event (read/write/published)

Declaration

procedure OnPreviewSetup( Sender: TObject );

Category

Preview

Description

This will allow you to modify the TRvRenderPreview component on a preview form as well as the preview form itself. Some functions, such as ZoomPageWidthFactor will need to be called in the OnPreviewShow event.

NOTE:

OnPreviewSetup is called before the form is shown and TRvRenderPreview is started.

     Top  := 10;

     Left := 10;

   end; { with }

end; { with }
