NAME
       toplevel - Create and manipulate toplevel 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.  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 con-figure configure
              figure 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  dis-played displayed
              played  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 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:

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

       pathName configure ?option? ?value option value ...?
              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 informa-tion information
              tion 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 correspond-ing corresponding
              ing 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  val-ues values
              ues 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.
