More control can be exercised over the rendering process with the - QSvgRenderer class, as this can be used to paint onto other paint devices, such as QImage - and QGLWidget. The renderer used by the widget can be obtained with the renderer() - function. - - Each QSvgWidget can be constructed with the file name of a SVG file, or they can be - constructed without a specific file to render and one can be supplied later. The load() - functions provide two different ways to load an SVG file: they accept either the file name - of an SVG file or a QByteArray containing the serialized XML representation of an SVG file. - - By default, the widget provides a size hint to reflect the size of the drawing that it - displays. If no data has been loaded, the widget provides the default QWidget size hint. - Subclass this class and reimplement sizeHint() if you need to customize this behavior. - - \sa QSvgRenderer, {Qt SVG C++ Classes}, QPicture -*/ - -class QSvgWidgetPrivate : public QWidgetPrivate -{ - Q_DECLARE_PUBLIC(QSvgWidget) -public: - QSvgRenderer *renderer; -}; - -/*! - Constructs a new SVG display widget with the given \a parent. -*/ -QSvgWidget::QSvgWidget(QWidget *parent) - : QWidget(*new QSvgWidgetPrivate, parent, {}) -{ - d_func()->renderer = new QSvgRenderer(this); - QObject::connect(d_func()->renderer, SIGNAL(repaintNeeded()), - this, SLOT(update())); -} - -/*! - Constructs a new SVG display widget with the given \a parent and loads the contents - of the specified \a file. -*/ -QSvgWidget::QSvgWidget(const QString &file, QWidget *parent) - : QWidget(*new QSvgWidgetPrivate, parent, {}) -{ - d_func()->renderer = new QSvgRenderer(file, this); - QObject::connect(d_func()->renderer, SIGNAL(repaintNeeded()), - this, SLOT(update())); -} - -/*! - Destroys the widget. -*/ -QSvgWidget::~QSvgWidget() -{ - -} - -/*! - Returns the renderer used to display the contents of the widget. -*/ -QSvgRenderer * QSvgWidget::renderer() const -{ - Q_D(const QSvgWidget); - return d->renderer; -} - - -/*! - \reimp -*/ -QSize QSvgWidget::sizeHint() const -{ - Q_D(const QSvgWidget); - if (d->renderer->isValid()) - return d->renderer->defaultSize(); - else - return QSize(128, 64); -} - - -/*! - \reimp -*/ -void QSvgWidget::paintEvent(QPaintEvent *) -{ - Q_D(QSvgWidget); - QStyleOption opt; - opt.init(this); - QPainter p(this); - style()->drawPrimitive(QStyle::PE_Widget, &opt, &p, this); - d->renderer->render(&p); -} - -/*! - Loads the contents of the specified SVG \a file and updates the widget. -*/ -void QSvgWidget::load(const QString &file) -{ - Q_D(const QSvgWidget); - d->renderer->load(file); -} - -/*! - Loads the specified SVG format \a contents and updates the widget. -*/ -void QSvgWidget::load(const QByteArray &contents) -{ - Q_D(const QSvgWidget); - d->renderer->load(contents); -} - -QT_END_NAMESPACE - -#endif // QT_NO_WIDGETS |
