C++ (Cpp) thumbnailReady Examples

Example #1

File: VideoThumbnailer.cpp Project: abhishekmurthy/Calligra

void VideoThumbnailer::slotCreateThumbnail(VideoData *videoData, const QSize &size)
{
        m_media.setCurrentSource(videoData->playableUrl());
        m_media.play();

        m_thumbnailSize = size;


        int retcode = 0;

                break;
            }
            kDebug() << "Seeking to " << (i * 3);
            m_media.seek(i * 3);
        }
        if (retcode) {
               kWarning() << "Unable to generate thumbnail for ";
               m_media.stop();
               return;
        }
        m_media.stop();

        emit thumbnailReady();
}

Example #2

File: thumbnailcache.cpp Project: kaltsi/qt-mobility

bool ThumbnailCache::event(QEvent *event)
{
    if (event->type() == QEvent::User) {
        ThumbnailEvent *thumbnailEvent = static_cast<ThumbnailEvent *>(event);

        QMutexLocker locker(&mutex);

        if (Thumbnail *thumbnail = cache.object(thumbnailEvent->url)) {
            thumbnail->pixmap = QPixmap::fromImage(thumbnailEvent->image);

            locker.unlock();

            emit thumbnailReady();
        }
        return true;
    } else {
        return QThread::event(event);
    }
}

    connect(&mThumbnailThread, SIGNAL(done(QImage, QSize)),
