How can I call the system default browser to display a webpage **INSIDE** my program

I mean just like a webkit widget, so i can insert it into m开发者_JAVA百科y layout.

use QWebView :

The QWebView class provides a widget that is used to view and edit web documents. QWebView is the main widget component of the QtWebKit web browsing module.

it's not the default system browser but you can display webpage with it.
