is there something that should be enabled before open the url, i use Qt 5.5.1
here is the code
Widget::Widget(QWidget *parent) :
wv = new QWebView;
You're facing bugs in an old Qt version. There's nothing for you to do other than updating Qt and switching to
QWebEngineView, or using platform APIs directly to launch a browser widget, e.g. the internet explorer ActiveX control using ActiveQt on Windows, or using the WebView object on OS X.
If you're tied to Qt 5.5.1 and you insist on using its built-in webkit, you have no choice but to use a debug build of Qt, run your project under a debugger, see where it crashes, and see if there's an upstream fix for it (upstream meaning in the webkit project itself). You'd then need to backport the fix to the version of webkit bundled in Qt 5.5.1. You might need to repeat this process a few times, since I'd expect you to run into more than one crashing bug in code that old.
