rated 0 times [ 5] [ 7] / answers: 1 / hits: 6577 / 10 Years ago, tue, december 16, 2014, 12:00:00

With QtWebkit it is possible to expose C++ objects to Javascript via QWebFrame::addToJavaScriptWindowObject as described in https://stackoverflow.com/a/20685002/595937

Can the same thing be accomplished in Qt 5.4 using QtWebEngine?

Exporting C++ objects to HTML/JS is not directly possible with QWebEngine.

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.
