Access to WebMessaging / window.postMessage

[queequac]

Hi everyone,

I am wondering if there is any chance to receive messages in C++ which were sent in the browser via the window.postMessage API (and vice versa, to send messages from C++ that are received in the browser the same way.)
Since my web application does already communicate to other web content in an iframe via this postMessage, it would be a clean solution to use the same approach for the communication to my native host without touching the web app itself.

Any hints welcome!


Kind regards, Roland
