[Interest] QtWebKit and open URL in new tab window

[neel patel]

Hi,

Yes. By using "_blank" - "createWindow" callback is getting called every
time we click on link.
You are right - We should use "_blank" instead of "_new" target attribute
as didn't find any reference document.

Thanks for your valuable suggestion.

Regards,
Neel Patel
