[Solved] Crash after QWebFrame::setHtml



  • I'm trying to set html content dynamically to document node in the main thread.

    @QWebElement dynamicContent = ui->webView->page()->mainFrame()->documentElement().findFirst("div#dynamicContent");
    if (QWebFrame *frame = dynamicContent.webFrame())
    {
    param = "<html><body></body></html>";
    frame->setHtml(param);
    }
    @
    These lines are executed normally, but after that i get read access violation with call stack

    Any googling or stackoverflowing of problem did not succeed. Had anyone else the same issue? What is the proper usage of QWebFrame::setHtml?

    Thank you

    UPDATE:
    code
    @
    QString content = "<html><body></body></html>";
    ui->webView->setHtml(content);
    @
    leads to the same crash
