Bug 29408 – [Qt] QWebPage does not schedule repaint when adding content via Javascript

• Status: RESOLVED

This bug report originated from issue QTBUG-3623
<http://bugreports.qt.nokia.com/browse/QTBUG-3623>

--- Description ---

I'm calling, using evaluateJavaScript(), a javascript method
written in my html page.

This javascript page add contents inside a <table id="mytable"></table>

However, in this specific case, the QWebView is not updated. After some
time, I move my mouse on my QWebView/Application, and suddenly I
can see my new elements added dynamically into my web page.

This case seems to only happen when I add "content" in my table:
it never happens when I update the "content", or remove the "content".

I solved my problem by doing:

QWebFrame *wbframe = this->mainFrame();
wbframe->evaluateJavaScript(cmd);
QWidget *widget = this->view();
if (widget!=NULL)
widget->update();

But you shouldn't be required to schedule your own repaint.
