  21  * nsIWinTaskbar
  22  *
  23  * This interface represents a service which exposes the APIs provided by the
  24  * Windows taskbar to applications.
  25  *
  26  * Starting in Windows 7, applications gain some control over their appearance
  27  * in the taskbar. By default, there is one taskbar preview per top level
  28  * window (excluding popups). This preview is represented by an
  29  * nsITaskbarWindowPreview object.
  30  *
  31  * An application can register its own "tab" previews. Such previews will hide
  32  * the corresponding nsITaskbarWindowPreview automatically (though this is not
  33  * reflected in the visible attribute of the nsITaskbarWindowPreview). These
  34  * tab previews do not have to correspond to tabs in the application - they can
  35  * vary in size, shape and location. They do not even need to be actual GUI
  36  * elements on the window. Unlike window previews, tab previews require most of
  37  * the functionality of the nsITaskbarPreviewController to be implemented.
  38  *
  39  * Applications can also show progress on their taskbar icon. This does not
  40  * interact with the taskbar previews except if the nsITaskbarWindowPreview is
  41  * made invisible in which case the progress is naturally not shown on that
  42  * window.
  43  *
  44  * When taskbar icons are combined as is the default in Windows 7, the progress
  45  * for those windows is also combined as defined here:
  46  * http://msdn.microsoft.com/en-us/library/dd391697%28VS.85%29.aspx
  47  *
  48  * Applications may also define custom taskbar jump lists on application shortcuts.
  49  * See nsIJumpListBuilder for more information.
