Detailed Description

The QPrinterInfo class gives access to information about existing printers.

Use the static functions to generate a list of QPrinterInfo objects. Each QPrinterInfo object in the list represents a single printer and can be queried for name, supported paper sizes, and whether or not it is the default printer.

Member Function Documentation


Constructs an empty QPrinterInfo object.

See also isNull().

QPrinterInfo::QPrinterInfo(const QPrinterInfo & other)

Constructs a copy of other.

This function was introduced in Qt 4.8.

QPrinterInfo::QPrinterInfo(const QPrinter & printer)

Constructs a QPrinterInfo object from printer.


Destroys the QPrinterInfo object. References to the values in the object become invalid.

[static] QList<QPrinterInfo> QPrinterInfo::availablePrinters()

Returns a list of available printers on the system.

[static] QPrinterInfo QPrinterInfo::defaultPrinter()

Returns the default printer on the system.

The return value should be checked using isNull() before being used, in case there is no default printer.

See also isNull().

bool QPrinterInfo::isDefault() const

Returns whether this printer is the default printer.

bool QPrinterInfo::isNull() const

Returns whether this QPrinterInfo object holds a printer definition.

An empty QPrinterInfo object could result for example from calling defaultPrinter() when there are no printers on the system.

QString QPrinterInfo::printerName() const

Returns the name of the printer.

See also QPrinter::setPrinterName().

QList<QPrinter::PaperSize> QPrinterInfo::supportedPaperSizes() const

Returns a list of supported paper sizes by the printer.

Not all printer drivers support this query, so the list may be empty. On Mac OS X 10.3, this function always returns an empty list.

This function was introduced in Qt 4.4.

QPrinterInfo & QPrinterInfo::operator=(const QPrinterInfo & other)

Sets the QPrinterInfo object to be equal to other.

This function was introduced in Qt 4.8.
