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
[Solved] This issue happens while calling QWebFrame::setHtml not from main thread.
Have solved this issue, and answer is DO NOT use setHtml method from thread, that differs from main.
