Detailed Description

Handles "property.set", "property.get" and "property.subscribe" commands sent from the Inviwo javascript API (see webbrowser/data/js/inviwoapi.js).

Flow of information between PropertyWidgetCEF and browser. Changes can start from Inviwo (left) or browser (right). Information is encoded in JSON format, e.g.

{"command":"subscribe", "path": 'myprocessor.myproperty', "onChange":
"onChangeCallbackJS", "propertyObserver": "observerName"}

Inviwo Browser (JavaScript) Property change | updateFromProperty() --> onChangeCallbackJS(property) | | OnQuery <------— inviwo.setProperty('myprocessor.myproperty', {value: 2.0}); from_json(json, property);

Member Function Documentation

OnLoadEnd()

void inviwo::PropertyCefSynchronizer::OnLoadEnd ( CefRefPtr< CefBrowser >  browser, CefRefPtr< CefFrame >  frame, int  httpStatusCode  )

overridevirtual

Synchronizes all widgets and sets their frame, called when frame has loaded.

OnQuery()

bool inviwo::PropertyCefSynchronizer::OnQuery ( CefRefPtr< CefBrowser >  browser, CefRefPtr< CefFrame >  frame, int64  query_id, const CefString &  request, bool  persistent, CefRefPtr< Callback >  callback  )

overridevirtual

Called due to cefQuery execution in message_router.html. Expects the request to be a JSON data object, see inviwoapi.js: {command: "subscribe", "path": propertyPath, "id":htmlId} for synchronizing property to change. {command: "property.set", "path":"PropertyIdentifier", "value":0.5} for setting a value {command: "property.get", "path": propertyPath} for getting a value. Currently only supports a single property in the request.
