The Init method Initializes the PrintPreviewClass object.
Implementation:
The PrintPreviewClass.Init method instantiates a PopupClass object for the PrintPreviewClass object, using the menu text defined in ABREPORT.TRN.
The image queue parameter names a QUEUE with the same structure as the PreviewQueue declared in \ABREPORT.INC as follows:
PreviewQueue QUEUE,TYPE
Filename STRING(128)
END
Example:
PrintPreviewQueue PreviewQueue !declare report image queue
PrtPrev PrintPreviewClass !declare PrtPrev object
CODE
PrtPrev.Init(PrintPreviewQueue) !initialize PrtPrev object
!program code
PrtPrev.Kill !shut down PrtPrev object
