Using the printing - systems on each platform, Qt applications can print to attached printers and - across networks to remote printers. Qt's printing system also enables PostScript - and PDF files to be generated, providing the foundation for basic report - generation facilities. - - \tableofcontents - - \section1 Classes Supporting Printing - - The following classes support the selecting and setting up of printers and - printing output. - - \annotatedlist printing - - \section1 Paint Devices and Printing - - In Qt, printers are represented by QPrinter, a paint device that provides - functionality specific to printing, such as support for multiple pages and - double-sided output. As a result, printing involves using a QPainter to paint - onto a series of pages in the same way that you would paint onto a custom - widget or image. - - \section2 Creating a QPrinter - - Although QPrinter objects can be constructed and set up without requiring user - input, printing is often performed as a result of a request by the user; - for example, when the user selects the \gui{File|Print...} menu item in a GUI - application. In such cases, a newly-constructed QPrinter object is supplied to - a QPrintDialog, allowing the user to specify the printer to use, paper size, and - other printing properties. - - \snippet examples/richtext/orderform/mainwindow.cpp 18 - - It is also possible to set certain default properties by modifying the QPrinter - before it is supplied to the print dialog. For example, applications that - generate batches of reports for printing may set up the QPrinter to - \l{QPrinter::setOutputFileName()}{write to a local file} by default rather than - to a printer. - - \section2 Painting onto a Page - - Once a QPrinter object has been constructed and set up, a QPainter can be used - to perform painting operations on it. We can construct and set up a painter in - the following way: - - \snippet doc/src/snippets/printing-qprinter/object.cpp 0 - - Since the QPrinter starts with a blank page, we only need to call the - \l{QPrinter::}{newPage()} function after drawing each page, except for the - last page. - - The document is sent to the printer, or written to a local file, when we call - \l{QPainter::}{end()}. - - \section2 Coordinate Systems - - QPrinter provides functions that can be used to obtain information about the - dimensions of the paper (the paper rectangle) and the dimensions of the - printable area (the page rectangle). These are given in logical device - coordinates that may differ from the physical coordinates used by the device - itself, indicating that the printer is able to render text and graphics at a - (typically higher) resolution than the user's display. - - Although we do not need to handle the conversion between logical and physical - coordinates ourselves, we still need to apply transformations to painting - operations because the pixel measurements used to draw on screen are often - too small for the higher resolutions of typical printers. - - \table - \row \li \b{Printer and Painter Coordinate Systems} - - The \l{QPrinter::}{paperRect()} and \l{QPrinter::}{pageRect()} functions - provide information about the size of the paper used for printing and the - area on it that can be painted on. - - The rectangle returned by \l{QPrinter::}{pageRect()} usually lies inside - the rectangle returned by \l{QPrinter::}{paperRect()}. You do not need to - take the positions and sizes of these area into account when using a QPainter - with a QPrinter as the underlying paint device; the origin of the painter's - coordinate system will coincide with the top-left corner of the page - rectangle, and painting operations will be clipped to the bounds of the - drawable part of the page. - - \li \inlineimage printer-rects.png - \endtable - - The paint system automatically uses the correct device metrics when painting - text but, if you need to position text using information obtained from - font metrics, you need to ensure that the print device is specified when - you construct QFontMetrics and QFontMetricsF objects, or ensure that each QFont - used is constructed using the form of the constructor that accepts a - QPaintDevice argument. - - \section1 Printing Widgets - - To print a widget, you can use the QWidget::render() function. As mentioned, - the printer's resolution is usually higher than the screen resolution, so you - will have to scale the painter. You may also want to position the widget on the - page. The following code sample shows how this may look. - - \snippet doc/src/snippets/widgetprinting.cpp 0 - - This will center the widget on the page and scale it so that it fits the page. - - \section1 Printing from Complex Widgets - - Certain widgets, such as QTextEdit and QGraphicsView, display rich content - that is typically managed by instances of other classes, such as QTextDocument - and QGraphicsScene. As a result, it is these content handling classes that - usually provide printing functionality, either via a function that can be used - to perform the complete task, or via a function that accepts an existing - QPainter object. Some widgets provide convenience functions to expose underlying - printing features, avoiding the need to obtain the content handler just to call - a single function. - - The following table shows which class and function are responsible for - printing from a selection of different widgets. For widgets that do not expose - printing functionality directly, the content handling classes containing this - functionality can be obtained via a function in the corresponding widget's API. - - \table - \header \li Widget \li Printing function \li Accepts - \row \li QGraphicsView \li QGraphicsView::render() \li QPainter - \row \li QSvgWidget \li QSvgRenderer::render() \li QPainter - \row \li QTextEdit \li QTextDocument::print() \li QPrinter - \row \li QTextLayout \li QTextLayout::draw() \li QPainter - \row \li QTextLine \li QTextLine::draw() \li QPainter - \endtable - - QTextEdit requires a QPrinter rather than a QPainter because it uses information - about the configured page dimensions in order to insert page breaks at the most - appropriate places in printed documents. -*/ - -/*! - \page pdf-licensing.html - \title Notes about PDF Licensing - \ingroup licensing - \brief Details of restrictions on the use of PDF-related trademarks. - - Please note that Adobe\reg places restrictions on the use of its trademarks - (including logos) in conjunction with PDF; e.g. "Adobe PDF".
