Description
   
    GtkHandleBox allows for widgets to be "torn out" of
    a window and to become their own floating window. The
    GtkHandleBox displays its child along with a handle
    that the user can drag to tear the widget out of its containing window and
    into its own float window. When the widget is torn out of the original
    window, its place is held by a thin ghost widget. By draging the float
    window back to the ghost widget and aligning the snap edge, the float
    window can be reattached.
   
   
    GtkHandleBox is a decendant of
    GtkBin, which means that it may container only one
    child. If you would like to have more than one widget in the same float
    window, you must first add those widgets to a container capable of holding
    more than one child, such as a GtkVBox.
