* \class MythUIWebBrowser
* \brief Provide a web browser widget.
*
* Uses QtWebKit and so requires Qt4.4.0 or later.
*
* This widget can display HTML documents from the net, a file or passed to it
* as a QString.
*
* This is how you would add the widget to a theme file :-
*
*
* <webbrowser name="webbrowser">
* <url>http://www.google.com/</url>
* <area>20,55,760,490</area>
* <zoom>1.4</zoom>
* <background color="white"/>
* </webbrowser>
*
* area is the screen area the widget should use.
* zoom is the initial text size.
* background is the default background color to use.
*
* The widget has two modes of operation active and inactive. When it's active
* and has focus it will show the mouse pointer, links will respond when
* clicked, the highlighed link can be changed and activated using the keyboard.
* In inactive mode it will just display a static image of the web document,
* you can scroll it but that is all.
*
* One thing to be aware of is you cannot show popups above this widget when it
* is in active mode and has focus so either call Active(false) or move the
* focus to another widget before showing the popup.
