	@keyterms:
		textbrowser browser widget class,
	@title:
		textbrowser class
	@type:
		class
	@short:
		Provides a class that can display html pages.
	@inherits:
		[class]widget[/class]
	@description:
		Provides a class that can display html pages with hypertext navigation.
	@functions:
		!fn: $setSource(<file_name:string>)
		With this you can display the page at szFile location (szFile include the path).
		!fn: $backward()
		Changes the document displayed to the previous document in the list of documents built by navigating links.
		!fn: $forward()
		Changes the document displayed to the next document in the list of documents built by navigating links.
		!fn: $home()
		Changes the document displayed to be the first document the browser displayed.
		!fn: $reload()
		Reloads the current set source.
		!fn: $linkClickedEvent(<link_href:string>)
		Triggered when a link is clicked by the user. The default implementation of this function
		emits the "linkClicked" signal.
	@signals:
		!sg: $linkClicked(<link_href:string>)
		This signal is emitted by the default implementation of the [classfnc]$linkClickedEvent[/classfnc]() function.
