Progress Bar in LineEdit

[TJSonic]

Of i forgot.
In the example loadProgress signal was connected to update() slot.

connect(webView, SIGNAL(loadProgress(int)),
       this, SLOT(update()));

connect(webView, SIGNAL(loadProgress(int)),
       this, SLOT(update()));

To copy to clipboard, switch view to plain text mode 

But i cant find such slot in urllineedit.cpp.

How to connect my webWiew loadProgress signal with lineEdits progress bar??
