Detailed Description

Helper class that relays audio parameter information to an object inside a WebBrowserComponent.

In order to create a relay you need to specify a WebBrowserComponent object and an identifier for the relayed state. This will result in a Javascript object becoming available inside the WebBrowserComponent under the provided identifier.

You can then use a WebComboBoxParameterAttachment as you would a ComboBoxParameterAttachment, to attach the relay to a RangedAudioParameter. This will synchronise the state and events of the Javascript object with the audio parameter at all times.

// Add a relay to your AudioProcessorEditor members
WebComboBoxRelay filterTypeComboRelay { webComponent, "filterTypeCombo" };

// In your Javascript GUI code you obtain an object from the framework
import * as Juce from "juce-framework-frontend";
const comboBoxState = Juce.getComboBoxState("filterTypeCombo");
