NAME


toplevel - Create and manipulate 'toplevel' main and popup window
    widgets






SYNOPSIS


toplevel pathName ?options?






STANDARD OPTIONS


-borderwidth	-highlightcolor	-pady
-cursor	-highlightthickness	-relief
-highlightbackground	-padx	-takefocus


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






WIDGET-SPECIFIC OPTIONS


Command-Line Name:	-background
Database Name:	background
Database Class:	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.






Command-Line Name:	-class
Database Name:	class
Database 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. Some window managers
      display the class name for windows in their dock while some others display
      the window title. The -class option may not be changed with the
      configure widget command.






Command-Line Name:	-colormap
Database Name:	colormap
Database Class:	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.






Command-Line Name:	-container
Database Name:	container
Database Class:	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.






Command-Line Name:	-height
Database Name:	height
Database Class:	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.






Command-Line Name:	-menu
Database Name:	menu
Database Class:	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.






Command-Line Name:	-screen
Database Name:	
Database Class:	



  

  
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.






Command-Line Name:	-use
Database Name:	use
Database Class:	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.






Command-Line Name:	-visual
Database Name:	visual
Database Class:	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.






Command-Line Name:	-width
Database Name:	width
Database Class:	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.
    
    

    

  








DESCRIPTION


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 Tk 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.






WIDGET COMMAND


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.








BINDINGS


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


Be aware that bindings on toplevels may receive events from
    subwidgets.
