Detailed Description

Handler for setting, getting, onChange and PropertyObservable of a property from HTML. Handles "property.set", "property.get" commands sent from the Inviwo javascript API (see webbrowser/data/js/inviwoapi.js) and sets property values on the Inviwo-side.

PropertyWidgetCEF must have a PropertyJSONConverter for its corresponding property. Thus, to add support for a new property it is only necessary to:

Implement to_json and from_json
Register converter using WebbrowserModule::registerPropertyJSONConverterAndWidget<PropertyWidgetCEF, MyNewProperty>()

Example code on HTML-side:

<script language="JavaScript">
// Initialize Inviwo API so that we can use it to synchronize properties
var inviwo = new InviwoAPI();
</script>
<input type="range" class="slider" id="PropertyIdentifier"
oninput="inviwo.setProperty('MyProcessor.MyProperty', {value: Number(this.value)})"> 

Note: Property serialization cannot be used to implement synchronization since it for example changes the property identifier if not set.
