Detailed Description

This class lets you preview pages.

Library: ilvprint

It is used by an IlvPrinterPreviewDisplayer instance.

As IlvPrinterPreviewDisplayer is an abstract class, the most common usage of the IlvPrinterPreview class is performed internally by the IlvPrinterPreviewDialog class.

Constructor & Destructor Documentation

◆ IlvPrinterPreview()

IlvPrinterPreview::IlvPrinterPreview ( IlvPrinter & referencePrinter )

Constructor.

The constructor initializes the object in a coherent state.

Parameters

referencePrinter This printer object is used to get the property of the actual printer.

Member Function Documentation

◆ checkErrorStatus()

virtual IlBoolean IlvPrinterPreview::checkErrorStatus ( ) const

virtual

Checks the error status of the printer.

Returns: IlTrue when the status is 'no error', IlFalse otherwise.

Implements IlvPrinter.

		IlvTransformer const &	transformer,
		IlvRegion const &	clip,
		IlInt	page
	)		const

Draws a page on a port.

Parameters

port	The port where the page will be drawn.
transformer	The transformer to apply to the drawing.
clip	The clipping region.
page	The page to draw.

Returns: IlFalse when an error occurred, or IlTrue otherwise.

◆ getPageNumber()

IlInt IlvPrinterPreview::getPageNumber ( ) const
