Detailed Description

This type is part of the QtAudioEngine 1.0 module.

An instance of AudioCategory can be accessed through AudioEngine.categories with its unique name and must be defined inside AudioEngine.

import QtQuick 2.0
import QtAudioEngine 1.0

Rectangle {
    color:"white"
    width: 300
    height: 500

    AudioEngine {
        id:audioengine

        AudioCategory {
            name: "sfx"
            volume: 0.8
        }

        AudioSample {
            name:"explosion"
            source: "explosion-02.wav"
        }

        Sound {
            name:"explosion"
            category: "sfx"
            PlayVariation {
                sample:"explosion"
            }
        }
    }

    MouseArea {
        anchors.fill: parent
        onPressed: {
            audioengine.categories["sfx"].volume = 0.5;
        }
    }
}

Sound instances can be grouped together by specifying the category property. When you change the volume of a category, all audio output from related instances will be affected as well.

Note: there will always be an AudioCategory named default whether you explicitly define it or not. If you do not specify any category for a Sound, it will be grouped into the default category.
