public class QSvgWidget
The QSvgWidget
class provides a widget that is used to display the contents of Scalable Vector Graphics (SVG) files. This class enables developers to display SVG drawings alongside standard widgets, and is used in much the same way as QLabel
is used for displaying text and bitmap images.
Since QSvgWidget
is a subclass of QWidget
, SVG drawings are rendered using the properties of the display. 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.
