QWebFrame evaluateJavaScript

[bunjee]

Hi Qt gurus,

I have a performance question.

I'm trying to design a high speed "QWebFrame Html append function":

QWebView::page()->mainFrame()->evaluateJavaScript(
QString("document.getElementById('%1').innerHTML += '%2'").
            arg(QString::number((int) chunk)).
            arg(html));

QWebView::page()->mainFrame()->evaluateJavaScript(
QString("document.getElementById('%1').innerHTML += '%2'").
            arg(QString::number((int) chunk)).
            arg(html));

To copy to clipboard, switch view to plain text mode 

After adding a few lines (1000x) it's getting very slow.

What would be the proper routine for doing that ?
