详细描述

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.

方法文档编制

QPrinterInfo.init ( self )

构造空 QPrinterInfo 对象。

另请参阅 isNull ().

QPrinterInfo.init ( self , QPrinterInfo src )

构造副本为 other .

该函数在 Qt 4.8 引入。

QPrinterInfo.init ( self , QPrinter printer )

构造 QPrinterInfo object from printer .

list-of-QPrinterInfo QPrinterInfo.availablePrinters ()

Returns a list of available printers on the system.

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.

另请参阅 isNull ().

bool QPrinterInfo.isDefault ( self )

Returns whether this printer is the default printer.

bool QPrinterInfo.isNull ( self )

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 ( self )

Returns the name of the printer.

另请参阅 QPrinter.setPrinterName ().

list-of-QPrinter.PageSize QPrinterInfo.supportedPaperSizes ( self )

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.

该函数在 Qt 4.4 引入。
