 /**
  * The Browser Extension is an extension (yes, no kidding) to
  * KParts::ReadOnlyPart, which allows a better integration of parts
  * with browsers (in particular Konqueror).
  * Remember that ReadOnlyPart only has openURL(KURL), with no other settings.
  * For full-fledged browsing, we need much more than that, including
  * many arguments about how to open this URL (see URLArgs), allowing
  * parts to save and restore their data into the back/forward history,
  * allowing parts to control the location bar URL, to requests URLs
  * to be opened by the hosting browser, etc.
  *
  * The part developer needs to define its own class derived from BrowserExtension,
  * to implement the virtual methods [and the standard-actions slots, see below].
  *
  * The way to associate the BrowserExtension with the part is to simply
  * create the BrowserExtension as a child of the part (in TQObject's terms).
  * The hosting application will look for it automatically.
  *
  * Another aspect of the browser integration is that a set of standard
  * actions are provided by the browser, but implemented by the part
  * (for the actions it supports).
  *
  * The following standard actions are defined by the host of the view :
  *
  * [selection-dependent actions]
  * @li @p cut : Copy selected items to clipboard and store 'not cut' in clipboard.
  * @li @p copy : Copy selected items to clipboard and store 'cut' in clipboard.
  * @li @p paste : Paste clipboard into view URL.
  * @li @p pasteTo(const KURL &) : Paste clipboard into given URL.
  * @li @p rename : Rename item in place.
  * @li @p trash : Move selected items to trash.
  * @li @p del : Delete selected items (couldn't call it delete!).
  * @li @p shred : Shred selected items (secure deletion) - DEPRECATED.
  * @li @p properties : Show file/document properties.
  * @li @p editMimeType : show file/document's mimetype properties.
  * @li @p searchProvider : Lookup selected text at default search provider
  *
  * [normal actions]
  * @li @p print : Print :-)
  * @li @p reparseConfiguration : Re-read configuration and apply it.
  * @li @p refreshMimeTypes : If the view uses mimetypes it should re-determine them.
  *
  *
  * The view defines a slot with the name of the action in order to implement the action.
  * The browser will detect the slot automatically and connect its action to it when
  * appropriate (i.e. when the view is active).
  *
  *
  * The selection-dependent actions are disabled by default and the view should
  * enable them when the selection changes, emitting enableAction().
  *
  * The normal actions do not depend on the selection.
  * You need to enable 'print' when printing is possible - you can even do that
  * in the constructor.
  *
  * A special case is the configuration slots, not connected to any action directly,
  * and having parameters.
  *
  * [configuration slot]
  * @li @p setSaveViewPropertiesLocally( bool ): If @p true, view properties are saved into .directory
