Detailed Description

Base class for the printer classes.

Library: ilvprint

This class is intended to be derived by implementing the member function makePort(). Its purpose is to encapsulate the printer information and handling.

See also: IlvPaperFormat

Member Enumeration Documentation

enum IlvPrinter::Orientation

This enumeration defines the possible values for the printing orientation.

mode of the IlvPrinter. This mode defines if the printer will print in portrait or landscape.

Enumerator
Portrait	The orientation is portrait.
Landscape	The orientation is landscape.

Constructor & Destructor Documentation

IlvPrinter::IlvPrinter ( IlvDisplay * display )

Constructor.

This is the constructor. It initializes the object in a coherent state. The default paper size is A4. The default paper mode is IlvPrinter::Printing. The default paper orientation is IlvPrinter::Portrait.

virtual IlvPrinter::~IlvPrinter ( )

virtual

Destructor.

The destructor actually does nothing, but it is declared as virtual so that inherited classes may overload it.

Member Function Documentation

Checks the error status of the printer.

This pure virtual member function must be overloaded in inherited classes.

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

void IlvPrinter::end ( )

Closes the dump device.

Closes the dump device and does all the necessary cleaning.

void IlvPrinter::forceDialogDisplay ( IlBoolean force )

void IlvPrinter::getMargins	(	IlvDim &	left,
		IlvDim &	right,
		IlvDim &	top,
		IlvDim &	bottom

Note that a modification of the orientation exchanges the axes, the previous left margin is now the top one, and so on.

Parameters

left	The left margin.
right	The right margin.

Returns the physical printable area.

This is the real size of a sheet of paper minus the printer's borders.

This pure virtual member function must be overloaded in inherited classes.

Returns: The usable physical printable area.

Implemented in IlvPSPrinter, IlvWindowsPrinter, and IlvPrinterPreview.
