问题描述
使用QtWebkit，可以通过 QWebFrame :: addToJavaScriptWindowObject 将C ++对象公开给Javascript，如
With QtWebkit it is possible to expose C++ objects to Javascript via QWebFrame::addToJavaScriptWindowObject as described in https://stackoverflow.com/a/20685002/595937
使用QtWebEngine可以在Qt 5.4中完成同样的事情吗？ / p>
Can the same thing be accomplished in Qt 5.4 using QtWebEngine?
推荐答案
使用QWebEngine无法直接将C ++对象导出为HTML / JS。
Exporting C++ objects to HTML/JS is not directly possible with QWebEngine.
相反，新推出的 QWebChannel 提供了HTML / JS和C ++之间的桥梁。请查看，尤其是示例。在今年的Qt开发者日期间，还有一个关于QWebChannel的非常好的介绍性讨论，这也可能是您感兴趣的。会谈的视频将在几周内上线。
Instead, the newly introduced QWebChannel provides a bridge between HTML/JS and C++. Have a look at the documentation, especially at the examples. There was also a quite good introductory talk about QWebChannel at this year's Qt Developer Days, which might also be of interest to you. The videos of the talks will go online in a few weeks.
