QtWebkits在Qt5.6以上版本被淘汰了，目前而言，QWebEngine有以下缺点：MinGW版本的Qt不支持，即便是Qt5.9.5版本以上也是不支持的。仅仅支持MSVC版本，接口暂时不丰富，无法和QWebFrame进行交互（使用了新的QWebChannel和QWebEnginePage组合进行交互）

在使用的时间安装新版本的Qt要安装Qt MSVC版本的，记得选择webengine组件

在example里面有很多例子，说不上有多友好，但也不错。

在webview，webengine，webenginewidgets三个目录下面都有，minimal是属于小巧的那种，代码很少，很容易读。

minimal.pro

TEMPLATE = app

QT += webenginewidgets

SOURCES += main.cpp

target.path = $$[QT_INSTALL_EXAMPLES]/webenginewidgets/minimal

INSTALLS += target

main.cpp
