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
QPrinterInfo::QPrinterInfo ()
Constructs an empty QPrinterInfo object.
See also isNull().
QPrinterInfo::QPrinterInfo ( const QPrinterInfo & src )
Constructs a copy of src.
QPrinterInfo::QPrinterInfo ( const QPrinter & printer )
Constructs a QPrinterInfo object from printer.
QPrinterInfo::~QPrinterInfo ()
Destroys the QPrinterInfo object. References to the values in the object become invalid.
QList<QPrinterInfo> QPrinterInfo::availablePrinters () [static]
Returns a list of available printers on the system.
QPrinterInfo QPrinterInfo::defaultPrinter () [static]
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().
Returns a list of supported paper sizes by the printer.
Not all printer drivers support this query, so the list may be empty.
This function was introduced in Qt 4.4.
QPrinterInfo & QPrinterInfo::operator= ( const QPrinterInfo & src )
Sets the QPrinterInfo object to be equal to src.
