Detailed Description

Web browsing widget.

Provide a web browser widget.

Can load and render local and remote html. Supports netscape plugins.

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.
