C++ (Cpp) EffectWidget Examples

Example #1

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

int main(int argv, char **args)
{
    QApplication app(argv, args);
    app.setApplicationName("Audio effect tester");

    Phonon::MediaObject *mediaObject = new Phonon::MediaObject;
    mediaObject->setCurrentSource(QString("/home/gvatteka/Music/Lumme-Badloop.ogg"));

    Phonon::AudioOutput *audioOutput =
        new Phonon::AudioOutput(Phonon::MusicCategory);

//! [0]
    QList<Phonon::EffectDescription> effectDescriptions =
            Phonon::BackendCapabilities::availableAudioEffects();
    Phonon::EffectDescription effectDescription = effectDescriptions.at(4);

    Phonon::Path path = Phonon::createPath(mediaObject, audioOutput);

//! [1]
    Phonon::Effect *effect = new Phonon::Effect(effectDescription);
    path.insertEffect(effect);
//! [0]

    Phonon::EffectWidget *effectWidget = new Phonon::EffectWidget(effect);
    effectWidget->show();
//! [1]

    mediaObject->play();

    effectWidget->setWindowTitle("Effect Name: " + effectDescription.name());

    app.exec();
}

Example #2

File: phononeffectparameter.cpp Project: dfizban/remixos-usb-tool

int main(int argv, char **args)
{
    QApplication app(argv, args);
    app.setApplicationName("effectsnippets");

    QList<Phonon::EffectDescription> effects =

    Phonon::Effect *effect = new Phonon::Effect(effects.at(3));
    
//![0]

    }
//![0]

//![1]
    Phonon::EffectWidget *effectWidget = new Phonon::EffectWidget(effect);
//![1]

Example #3

File: mainwindow.cpp Project: Rookiee/Qt_Codes

    // 使用指定的音频效果的描述来创建音频效果
    Phonon::Effect *effect = new Phonon::Effect(effectDescription);
    // 在路径中插入音频效果
    path.insertEffect(effect);
    // 创建效果部件，它可以用来更改效果中的参数
    Phonon::EffectWidget *effectWidget = new Phonon::EffectWidget(effect);
