Oh well, did not expect the solution to be that simple (if this is actually the case)

Understanding the Qt Framework's library/module design is pain :D

@sierdzio setting an alias for the StackView and then calling root.stack.push worked for me. Thanks!

It is possible to call c/c++ functions from javascript as well as call javascript from c/c++.

I figured out how to export custom functions, but there's still a problem with exporting the runtime ones. I am adding the -s EXPORTED_RUNTIME_METHODS=UTF8ToString argument and keep receiving "Uncaught RuntimeError: Aborted('UTF8ToString' was not exported. add it to EXPORTED_RUNTIME_METHODS (see the FAQ))" error.

Hi,

To add to @kshegunov, you might be interested by the Extending Qt Applications part of the Plugin HowTo in Qt's documentation.
