See the options manual entry for details on the standard
    options.








[-background background]
    This option is the same as the standard background option except that
    its value may also be specified as an empty string. In this case, the widget
    will display no background or border, and no colors will be consumed from
    its colormap for its background and border. [-class
    class] Specifies a class for the window. This class will be
    used when querying the option database for the window's other options, and
    it will also be used later for other purposes such as bindings. The
    class option may not be changed with the configure widget
    command. [-colormap colormap]
    Specifies a colormap to use for the window. The value may be either
    new, in which case a new colormap is created for the window and its
    children, or the name of another window (which must be on the same screen
    and have the same visual as pathName), in which case the new window
    will use the colormap from the specified window. If the colormap
    option is not specified, the new window uses the default colormap of its
    screen. This option may not be changed with the configure widget
    command. [-container container] The
    value must be a boolean. If true, it means that this window will be used as
    a container in which some other application will be embedded (for example, a
    Tk toplevel can be embedded using the -use option). The window will
    support the appropriate window manager protocols for things like geometry
    requests. The window should not have any children of its own in this
    application. This option may not be changed with the configure widget
    command. [-height height] Specifies
    the desired height for the window in any of the forms acceptable to
    Tk_GetPixels. If this option is less than or equal to zero then the
    window will not request any size at all. [-menu
    menu] Specifies a menu widget to be used as a menubar. On the
    Macintosh, the menubar will be displayed across the top of the main monitor.
    On Microsoft Windows and all UNIX platforms, the menu will appear across the
    toplevel window as part of the window dressing maintained by the window
    manager. [-screen ] Specifies the
    screen on which to place the new window. Any valid screen name may be used,
    even one associated with a different display. Defaults to the same screen as
    its parent. This option is special in that it may not be specified via the
    option database, and it may not be modified with the configure widget
    command. [-use use] This option is
    used for embedding. If the value is not an empty string, it must be the
    window identifier of a container window, specified as a hexadecimal string
    like the ones returned by the winfo id command. The toplevel widget
    will be created as a child of the given container instead of the root window
    for the screen. If the container window is in a Tk application, it must be a
    frame or toplevel widget for which the -container option was
    specified. This option may not be changed with the configure widget
    command. [-visual visual] Specifies
    visual information for the new window in any of the forms accepted by
    Tk_GetVisual. If this option is not specified, the new window will
    use the default visual for its screen. The visual option may not be
    modified with the configure widget command.
    [-width width] Specifies the desired
    width for the window in any of the forms acceptable to Tk_GetPixels.
    If this option is less than or equal to zero then the window will not
    request any size at all.












The toplevel command creates a new toplevel widget (given
    by the pathName argument). Additional options, described above, may
    be specified on the command line or in the option database to configure
    aspects of the toplevel such as its background color and relief. The
    toplevel command returns the path name of the new window.


A toplevel is similar to a frame except that it is created as a
    top-level window: its X parent is the root window of a screen rather than
    the logical parent from its path name. The primary purpose of a toplevel is
    to serve as a container for dialog boxes and other collections of widgets.
    The only visible features of a toplevel are its background color and an
    optional 3-D border to make the toplevel appear raised or sunken.










The toplevel command creates a new Tcl command whose name
    is the same as the path name of the toplevel's window. This command may be
    used to invoke various operations on the widget. It has the following
    general form:




pathName option ?arg arg ...?



PathName is the name of the command, which is the same as the toplevel
  widget's path name. Option and the args determine the exact
  behavior of the command. The following commands are possible for toplevel
  widgets:


  

  
Returns the current value of the configuration option given by
      option. Option may have any of the values accepted by the
      toplevel command.

  

  
Query or modify the configuration options of the widget. If no
      option is specified, returns a list describing all of the available
      options for pathName (see Tk_ConfigureInfo for information
      on the format of this list). If option is specified with no
      value, then the command returns a list describing the one named
      option (this list will be identical to the corresponding sublist of the
      value returned if no option is specified). If one or more
      option-value pairs are specified, then the command modifies the
      given widget option(s) to have the given value(s); in this case the
      command returns an empty string. Option may have any of the values
      accepted by the toplevel command.
    

  










When a new toplevel is created, it has no default event bindings:
    toplevels are not intended to be interactive.
