Tonight I had an idea to make what I want.
To comunicate JUCE with a html page contained in webBrowserComponent, we could invoke an URL that load a custumized page in our file system.
In our JUCE app, we could receive and decode the httpRequests and then send to our page a response with contains comands like “NothingToDoFromHere” or “HeyCentreTheMapInPosition:10.2323,30.2323”.
… A very simple web server in the juce/host side and a little mini-framework to decode httpResponses/commands in html side.
(Sorry for my poor english)
