What the hell is the web browser encapsulated in QT? why do I write a lot of CSS attributes that are not supported?

as a pc client, the QT5, client comes with a web browser and asks them that it comes with QT, but when I do front-end development on this browser, some of the CSS attributes are incompatible, such as this: cursor: pointer;, it seems to be unknown, and how can this thing open the console, just like Google browser? use developer tools.

Webkit , check it out. For
debugging, the early version of Qt4 does not have a console, but there is a debugging class that you can try using QWebInspector and embed it into a QDialog, like this:

QDialog dlg;

QWebInspector *i = new QWebInspector(this);
dlg.setLayout(new QVBoxLayout());
dlg.layout()->addWidget(i);
dlg.setModal(false);
dlg.show();
dlg.raise();
dlg.activateWindow();
