[Qt-interest] Invoke function in JavaScript

[Joshua Lee]

Hi Gopalakrishna,
I would like to export Qt TestApi object to javascript, because some of
the methods takes long time and can not response instantly. So the
best way is using async way that Qt push the results to javascript
when it finish the operation.


Best regards,
Joshua
