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

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

virtual IlBoolean IlvPrinter::checkErrorStatus ( ) const

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)

Sets whether the dialog must be displayed.

This is meaningful only if a setting dialog is attached to the printer.

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.
