示例1: drawingArrived
void CollaborativeDrawingWidget::drawingArrived(QString sessionName, QByteArray picData, bool isInitialState)
{
// this slot will be invoked when the user joins a new session and the server
// sends the current drawing state for this session
QPicture pic;
qWarning() << "Session state data of size : " << picData.size() << "from session" << sessionName;
if(isInitialState) {
// set the session name
m_currentSession = sessionName;
// clear up any old data
getDrawingData()->clear();
// the widget should be enabled now
setEnabled(true);
}
pic.setData(picData.constData(), picData.size());
// commit the new data
BaseDrawingWidget::commitDrawing(pic);
}
示例2: svgAsPicture
QPicture QgsSvgCache::svgAsPicture( const QString &path, double size, const QColor &fill, const QColor &stroke, double strokeWidth,
double widthScaleFactor, bool forceVectorOutput, double fixedAspectRatio )
{
QMutexLocker locker( &mMutex );
QgsSvgCacheEntry *currentEntry = cacheEntry( path, size, fill, stroke, strokeWidth, widthScaleFactor, fixedAspectRatio );
//if current entry picture is 0: cache picture for entry
//update stats for memory usage
if ( !currentEntry->picture )
{
cachePicture( currentEntry, forceVectorOutput );
trimToMaximumSize();
}
QPicture p;
// For some reason p.detach() doesn't seem to always work as intended, at
// least with QT 5.5 on Ubuntu 16.04
// Serialization/deserialization is a safe way to be ensured we don't
// share a copy.
p.setData( currentEntry->picture->data(), currentEntry->picture->size() );
return p;
