    @class wxSashWindow
    @wxheader{sashwin.h}

    wxSashWindow allows any of its edges to have a sash which can be dragged
    to resize the window. The actual content window will be created by the
    application
    as a child of wxSashWindow. The window (or an ancestor) will be notified of a
    drag
    via a wxSashEvent notification.

    @beginStyleTable
    @style{wxSW_3D}:
           Draws a 3D effect sash and border.
    @style{wxSW_3DSASH}:
           Draws a 3D effect sash.
    @style{wxSW_3DBORDER}:
           Draws a 3D effect border.
    @style{wxSW_BORDER}:
           Draws a thin black border.
    @endStyleTable

    @beginEventTable
    @event{EVT_SASH_DRAGGED(id, func)}:
           Process a wxEVT_SASH_DRAGGED event, when the user has finished
           dragging a sash.
    @event{EVT_SASH_DRAGGED_RANGE(id1, id2, func)}:
           Process a wxEVT_SASH_DRAGGED_RANGE event, when the user has
           finished dragging a sash. The event handler is called when windows
           with ids in the given range have their sashes dragged.
