Qt provides classes for rendering and + generating SVG drawings. This example allows the user to create a simple + picture and save it to an SVG file. + + The example consists of two classes: \c Window and \c DisplayWidget. + + The \c Window class contains the application logic and constructs the user + interface from a Qt Designer UI file as described in the + \l{Using a Designer UI File in Your Application#The Multiple Inheritance Approach}{Qt Designer manual}. + It also contains the code to write an SVG file. + + The \c DisplayWidget class performs all the work of painting a picture on + screen. Since we want the SVG to resemble this picture as closely as + possible, we make this code available to the \c Window class so that it can + be used to generate SVG files. + + \section1 The DisplayWidget Class + + The \c DisplayWidget class displays a drawing consisting of a selection of + elements chosen by the user. These are defined using \c Shape and + \c Background enums that are included within the class definition: + + \snippet svggenerator/displaywidget.h DisplayWidget class definition + + Much of this class is used to configure the appearance of the drawing. The + \c paintEvent() and \c paint() functions are most relevant to the purpose + of this example, so we will describe these here and leave the reader to + look at the source code for the example to see how shapes and colors are + handled. + + We reimplement the QWidget::paintEvent() function to display the drawing + on screen: + + \snippet svggenerator/displaywidget.cpp paint event + + Here, we only construct a QPainter object, begin painting on the device + and set a render hint for improved output quality before calling the + \c paint() function to perform the painting itself. When this returns, + we close the painter and return. + + The \c paint() function is designed to be used for different painting + tasks. In this example, we use it to draw on a \c DisplayWidget instance + and on a QSvgGenerator object. We show how the painting is performed to + demonstrate that there is nothing device-specific about the process: + + \snippet svggenerator/displaywidget.cpp paint function + + \section1 The Window Class + + The \c Window class represents the example's window, containing the user + interface, which has been created using Qt Designer: + + \snippet svggenerator/window.h Window class definition + + As with the \c DisplayWidget class, we concentrate on the parts of the code + which are concerned with painting and SVG generation. In the \c Window + class, the \c saveSvg() function is called whenever the \b{Save As...} + button is clicked; this connection was defined in the \c{window.ui} file + using Qt Designer. + + The start of the \c saveSvg() function performs the task of showing a file + dialog so that the user can specify a SVG file to save the drawing to. + + \snippet svggenerator/window.cpp save SVG + + In the rest of the function, we set up the generator and configure it to + generate output with the appropriate dimensions and write to the + user-specified file. We paint on the QSvgGenerator object in the same way + that we paint on a widget, calling the \c DisplayWidget::paint() function + so that we use exactly the same code that we used to display the drawing. + + The generation process itself begins with the call to the painter's + \l{QPainter::}{begin()} function and ends with call to its + \l{QPainter::}{end()} function. The QSvgGenerator paint device relies on + the explicit use of these functions to ensure that output is written to + the file. + + \section1 Further Reading + + The \l{SVG Viewer Example} shows how to display SVG drawings in an + application, and can be used to show the contents of SVG files created + by this example. + + See the QtSvg module documentation for more information about SVG and Qt's + SVG classes. +*/ diff --git a/examples/svg/svggenerator/forms/window.ui b/examples/svg/svggenerator/forms/window.ui new file mode 100644 index 0000000..bf11908 --- /dev/null +++
