Hi André,
 
please can you have an idea for how to use 
 "QVariant QWebFrame::evaluateJavaScript ( const QString & scriptSource )   [slot]"

i do this QVariant script =v.page()->mainFrame()->evaluateJavaScript (frameText ); 

but i don't now what is the init value of  QVariant ???
and for QStrig & scritSource it's the url of file .js or what ??

thank's in advance,
Sanaa.
