[Interest] WebVuew::runJavaScript problems

Fri Aug 24 01:41:12 CEST 2018

Hi Jason,

When are you calling runJavaScript?  How are you loading the page?  How 
do you know that the page has finished loading?  I suggest to listen for 
the loadingChanged signal and then do the processing there when the 
status is LoadSucceededStatus.  I assume that you are calling 
QtWebView::initialize() during application startup?

Hope that helps, Tony
