## Detailed Description

The EffectWidget class provides a widget to control the parameters of an Effect.

The EffectWidget class provides a widget, with which an effects parameters can be controlled. The widget does not have an API, and is constructed with the Effect, of which parameters should be controlled.

         Phonon::Effect *effect = new Phonon::Effect(effectDescription);
         path.insertEffect(effect);

         Phonon::EffectWidget *effectWidget = new Phonon::EffectWidget(effect);
         effectWidget->show();

The following image shows an example of an effect widget.

Note that some audio effects do not have parameters, and the widget will then not show() at all.
