Example #6

File: q3picture.cpp Project: Akheon23/chromecast-mirrored-source.vendor

/*!
    \fn bool Q3Picture::save(QIODevice *device, const char *format)

    Saves the picture in the specified \a format to the given \a device.
    Returns true if the save is successful. Returns false if, for
    example, the picture is still being painted, i.e., QPainter::end()
    has not yet been called.

    Note that when using the save() function to save SVG files, the
    format must be specified. For example:

    \snippet doc/src/snippets/code/src_qt3support_painting_q3picture.cpp 1

    \sa load()
*/
bool Q3Picture::save(QIODevice *dev, const char *format)
{
    if (paintingActive()) {
        qWarning("Q3Picture::save: still being painted on. "
                  "Call QPainter::end() first");
        return false;
    }

    if (qstricmp(format, "svg") == 0) {

	QPainter p(&svg);
	if (!play(&p))
	    return false;
	svg.setBoundingRect(boundingRect());
	return svg.save(dev);
    }

    given \a fileName.
