Hello all,
I am back with another weird thing.
I am using Qt 5.5 on Ubuntu 16.04. I am using the webkit widget to display some html in the application. The html is being served from a local web server on port 8080. The URL has a format like this: http://localhost:8080/SomeDirectory/index.html. As a side note, I have also tried http://127.0.0.1:8080/SomeDirectory/index.html. The web server is lighttpd.
What happens is this:
1. Lighttpd is running
2. Network cable is plugged in and network is properly configured
3. I open the webkit widget and see the html display properly
4. Network cable is un-plugged
5. I open the webkit widget and see a blank screen with nothing in it
6. I try it with very basic html — a <html><body><h1>Hello World</h1></body></html> and it is still blank
7. I try it with a browser going to the same files and they all work
8. I tried it running the webkit widget from inside of qtcreator and same result — blank
9. To test that I was not doing something wrong with my widget, I tested it with the FancyBrowser example that is with qtcreator and got the same results — blank.
10. I plug the network cable back in and it all works again
No errors are thrown that I can see.
Any ideas?
Thanks!
-Jason
