WIDGET-SPECIFIC OPTIONS
       Command-Line Name:-postcommand
       Database Name:  postCommand
       Database Class: Command

              If  this option is specified then it provides a Tcl
              command to execute each time the  menu  is  posted.
              The  command  is invoked by the post widget command
              before posting the menu. Note that in 8.0 on Macin-
              tosh  and  Windows,  all commands in a menu systems
              are executed before any are posted. This is due  to
              the  limitations  in the individual platforms' menu
              managers.

       Command-Line Name:-selectcolor
       Database Name:  selectColor
       Database Class: Background

              For menu entries that are check  buttons  or  radio
              buttons, this option specifies the color to display
              in the indicator when the  check  button  or  radio
              button is selected.

       Command-Line Name:-tearoff
       Database Name:  tearOff
       Database Class: TearOff

              This option must have a proper boolean value, which
              specifies whether or not the menu should include  a
              tear-off entry at the top.  If so, it will exist as
              entry 0 of the menu and the other entries will num-
              ber  starting  at  1.   The  default  menu bindings
              arrange for the menu to be torn off when the  tear-
              off entry is invoked.

       Command-Line Name:-tearoffcommand
       Database Name:  tearOffCommand
       Database Class: TearOffCommand

              If this option has a non-empty value, then it spec-
              ifies a Tcl command to invoke whenever the menu  is
              torn  off.   The actual command will consist of the
              value of this option, followed by a space, followed
              by  the  name  of  the  menu  window, followed by a
              space, followed by the name of the name of the torn
              off  menu  window.  For example, if the option's is
              ``a b'' and menu .x.y is torn off to create  a  new
              menu  .x.tearoff1,  then  the  command  ``a  b .x.y
              .x.tearoff1'' will be invoked.

       Command-Line Name:-title
       Database Name:  title
       Database Class: Title

              The string will be used to title the window created
              when  this  menu is torn off. If the title is NULL,
              then the window will have the title of the menubut-
              ton or the text of the cascade item from which this
              menu was invoked.

       Command-Line Name:-type
       Database Name:  type
       Database Class: Type

              This option can be one of menubar, tearoff, or nor-
              mal, and is set when the menu is created. While the
              string returned by the configuration database  will
              change  if  this  option  is changed, this does not
              affect the menu widget's behavior. This is used  by
              the  cloning mechanism and is not normally set out-
              side of the Tk library.


INTRODUCTION
       The menu command creates a new top-level window (given  by
       the  pathName  argument)  and makes it into a menu widget.
       Additional options, described above, may be  specified  on
       the  command  line  or in the option database to configure
       aspects of the menu such as its colors and font.  The menu
       command  returns  its pathName argument.  At the time this
       command is invoked, there must not exist  a  window  named
       pathName, but pathName's parent must exist.

       A  menu is a widget that displays a collection of one-line
       entries arranged in one or more columns.  There exist sev-
       eral different types of entries, each with different prop-
       erties.  Entries of different types may be combined  in  a
       single  menu.  Menu entries are not the same as entry wid-
       gets.  In fact, menu entries are not  even  distinct  wid-
       gets; the entire menu is one widget.

       Menu  entries  are  displayed  with  up  to three separate
       fields.  The main field is a label in the form of  a  text
       string,  a  bitmap, or an image, controlled by the -label,
       -bitmap,  and  -image  options  for  the  entry.   If  the
       -accelerator  option is specified for an entry then a sec-
       ond textual field is displayed to the right of the  label.
       The  accelerator  typically describes a keystroke sequence
       that may be typed in the application  to  cause  the  same
       result  as invoking the menu entry.  The third field is an
       indicator.  The indicator is present only for  checkbutton
       or radiobutton entries.  It indicates whether the entry is
       selected or not, and is  displayed  to  the  left  of  the
       entry's string.

       In  normal  use,  an entry becomes active (displays itself
       differently) whenever the mouse pointer is over the entry.
       If  a  mouse  button  is  released over the entry then the
       entry is invoked.  The effect of invocation  is  different
       for  each type of entry; these effects are described below
       in the sections on individual entries.

       Entries may be disabled, which  causes  their  labels  and
       accelerators  to  be  displayed  with  dimmer colors.  The
       default menu bindings will not allow a disabled  entry  to
       be  activated  or  invoked.   Disabled  entries may be re-
       enabled, at which point it becomes  possible  to  activate
       and invoke them again.

       Whenever  a  menu's  active  entry is changed, a <<MenuSe-
       lect>> virtual event is send to the menu. The active  item
       can  then  be  queried from the menu, and an action can be
       taken, such as setting context-sensitive help text for the
       entry.


COMMAND ENTRIES
       The  most  common  kind  of menu entry is a command entry,
       which behaves much like a button widget.  When  a  command
       entry is invoked, a Tcl command is executed.  The Tcl com-
       mand is specified with the -command option.


SEPARATOR ENTRIES
       A separator is an entry that is displayed as a  horizontal
       dividing  line.   A  separator  may  not  be  activated or
       invoked, and it has no behavior  other  than  its  display
       appearance.


CHECKBUTTON ENTRIES
       A  checkbutton  menu entry behaves much like a checkbutton
       widget.  When it is invoked  it  toggles  back  and  forth
       between  the  selected  and  deselected  states.  When the
       entry is selected, a particular value is stored in a  par-
       ticular global variable (as determined by the -onvalue and
       -variable options for the entry);  when the entry is dese-
       lected  another value (determined by the -offvalue option)
       is stored in the global variable.   An  indicator  box  is
       displayed to the left of the label in a checkbutton entry.
       If the entry is selected then the  indicator's  center  is
       displayed  in  the  color given by the -selectcolor option
       for the entry; otherwise the indicator's  center  is  dis-
       played  in  the background color for the menu.  If a -com-
       mand option is specified for a checkbutton entry, then its
       value is evaluated as a Tcl command each time the entry is
       invoked;  this happens after toggling the entry's selected
       state.


RADIOBUTTON ENTRIES
       A  radiobutton  menu entry behaves much like a radiobutton
       widget.  Radiobutton entries are organized  in  groups  of
       which  only one entry may be selected at a time.  Whenever
       a particular entry becomes selected it stores a particular
       value  into a particular global variable (as determined by
       the -value and -variable options  for  the  entry).   This
       action  causes  any  previously-selected entry in the same
       group to  deselect  itself.   Once  an  entry  has  become
       selected,  any  change  to the entry's associated variable
       will cause the entry  to  deselect  itself.   Grouping  of
       radiobutton  entries  is  determined  by  their associated
       variables:  if two entries have the same associated  vari-
       able  then  they are in the same group.  An indicator dia-
       mond is displayed  to  the  left  of  the  label  in  each
       radiobutton  entry.   If  the  entry  is selected then the
       indicator's center is displayed in the color given by  the
       -selectcolor  option  for the entry; otherwise the indica-
       tor's center is displayed in the background color for  the
       menu.  If a -command option is specified for a radiobutton
       entry, then its value is evaluated as a Tcl  command  each
       time  the  entry is invoked;  this happens after selecting
       the entry.


CASCADE ENTRIES
       A cascade entry is one with an associated menu (determined
       by the -menu option).  Cascade entries allow the construc-
       tion of cascading menus.  The postcascade  widget  command
       can  be  used  to post and unpost the associated menu just
       next to of the cascade entry.  The associated menu must be
       a  child of the menu containing the cascade entry (this is
       needed in order for menu traversal to work correctly).

       A cascade entry posts its associated menu  by  invoking  a
       Tcl command of the form
              menu post x y
       where  menu is the path name of the associated menu, and x
       and y are the root-window coordinates of  the  upper-right
       corner  of  the  cascade  entry.  On Unix, the lower-level
       menu is unposted by executing a Tcl command with the form
              menu unpost
       where menu is the name of the associated menu.   On  other
       platforms,  the  platform's  native  code  takes  care  of
       unposting the menu.

       If a -command option is specified for a cascade entry then
       it  is  evaluated  as  a Tcl command whenever the entry is
       invoked. This is not supported on Windows.


TEAR-OFF ENTRIES
       A tear-off entry appears at the top of the menu if enabled
       with  the  tearOff  option.   It  is  not  like other menu
       entries in that it cannot be created with the  add  widget
       command  and cannot be deleted with the delete widget com-
       mand.  When a tear-off entry is created it  appears  as  a
       dashed  line  at  the  top of the menu.  Under the default
       bindings, invoking the tear-off entry  causes  a  torn-off
       copy to be made of the menu and all of its submenus.


MENUBARS
       Any  menu  can  be  set as a menubar for a toplevel window
       (see toplevel command for syntax). On the Macintosh, when-
       ever  the  toplevel is in front, this menu's cascade items
       will appear in the menubar across the top of the main mon-
       itor.  On Windows and Unix, this menu's items will be dis-
       played in a menubar accross the top of the  window.  These
       menus will behave according to the interface guidelines of
       their platforms. For every menu set as a menubar, a  clone
       menu is made. See the CLONES section for more information.

       As noted, menubars may  behave  differently  on  different
       platforms.   One  example of this concerns the handling of
       checkbuttons and radiobuttons within the menu.   While  it
       is  permitted to put these menu elements on menubars, they
       may not be drawn with indicators on some platforms, due to
       system restrictions.


SPECIAL MENUS IN MENUBARS
       Certain  menus in a menubar will be treated specially.  On
       the Macintosh, access to the special Apple and Help  menus
       is provided. On Windows, access to the Windows System menu
       in each window is provided. On X Windows, a special right-
       justified help menu is provided. In all cases, these menus
       must be created with the command name of the menubar  menu
       concatenated with the special name. So for a menubar named
       .menubar, on the Macintosh, the  special  menus  would  be
       .menubar.apple  and .menubar.help; on Windows, the special
       menu would be .menubar.system; on X Windows, the help menu
       would be .menubar.help.

       When  Tk  sees an Apple menu on the Macintosh, that menu's
       contents make up the first items of the Apple menu on  the
       screen  whenever  the  window containing the menubar is in
       front. The menu is the first one that the  user  sees  and
       has  a title which is an Apple logo.  After all of the Tk-
       defined items, the menu will have a separator, followed by
       all  of  the  items in the user's Apple Menu Items folder.
       Since the System uses a different menu  definition  proce-
       dure  for  the  Apple menu than Tk uses for its menus, and
       the system APIs do not fully support everything  Tk  tries
       to do, the menu item will only have its text displayed. No
       font attributes, images, bitmaps, or colors will  be  dis-
       played.  In addition, a menu with a tearoff item will have
       the tearoff item displayed as "(TearOff)".

       When Tk see a Help menu on the Macintosh, the menu's  con-
       tents  are appended to the standard help menu on the right
       of the user's menubar whenever the user's  menubar  is  in
       front.  The first items in the menu are provided by Apple.
       Similar to the Apple Menu, cusomization in  this  menu  is
       limited to what the system provides.

       When  Tk  sees  a  System  menu  on Windows, its items are
       appended to the system menu that the menubar  is  attached
       to. This menu has an icon representing a spacebar, and can
       be invoked with the mouse or by typing Alt+Spacebar.   Due
       to  limitations in the Windows API, any font changes, col-
       ors, images, bitmaps, or tearoff images will not appear in
       the system menu.

       When Tk see a Help menu on X Windows, the menu is moved to
       be last in the menubar and is right justified.


CLONES
       When a menu is set as a menubar for a toplevel window,  or
       when a menu is torn off, a clone of the menu is made. This
       clone is a menu widget in its own right, but it is a child
       of the original. Changes in the configuration of the orig-
       inal are reflected in the clone.  Additionally,  any  cas-
       cades  that  are  pointed  to are also cloned so that menu
       traversal will  work  right.  Clones  are  destroyed  when
       either the tearoff or menubar goes away, or when the orig-
       inal menu is destroyed.


WIDGET COMMAND
       The menu command creates a new Tcl command whose  name  is
       pathName.   This  command  may  be  used to invoke various
       operations on the widget.  It has  the  following  general
       form:
              pathName option ?arg arg ...?
       Option  and  the  args determine the exact behavior of the
       command.

       Many of the widget commands for a menu take as  one  argu-
       ment  an  indicator  of which entry of the menu to operate
       on.  These indicators are called indexes and may be speci-
       fied in any of the following forms:

       number      Specifies  the entry numerically, where 0 cor-
                   responds to the top-most entry of the menu,  1
                   to the entry below it, and so on.

       active      Indicates  the entry that is currently active.
                   If no entry is active then this form is equiv-
                   alent  to none.  This form may not be abbrevi-
                   ated.

       end         Indicates the bottommost entry  in  the  menu.
                   If  there are no entries in the menu then this
                   form is equivalent to none.  This form may not
                   be abbreviated.

       last        Same as end.

       none        Indicates  ``no  entry at all'';  this is used
                   most commonly  with  the  activate  option  to
                   deactivate  all  the  entries in the menu.  In
                   most cases the specification  of  none  causes
                   nothing to happen in the widget command.  This
                   form may not be abbreviated.

       @number     In this form, number is treated as a y-coordi-
                   nate  in the menu's window;  the entry closest
                   to that y-coordinate is  used.   For  example,
                   ``@0''  indicates  the  top-most  entry in the
                   window.

       pattern     If the index doesn't satisfy one of the  above
                   forms then this form is used.  Pattern is pat-
                   tern-matched against the label of  each  entry
                   in the menu, in order from the top down, until
                   a matching  entry  is  found.   The  rules  of
                   Tcl_StringMatch are used.

       The  following  widget commands are possible for menu wid-
       gets:

       pathName activate index
              Change the state of the entry indicated by index to
              active  and  redisplay  it using its active colors.
              Any previously-active  entry  is  deactivated.   If
              index  is  specified  as  none, or if the specified
              entry is disabled, then the menu ends  up  with  no
              active entry.  Returns an empty string.

       pathName add type ?option value option value ...?
              Add a new entry to the bottom of the menu.  The new
              entry's type is given by type and must  be  one  of
              cascade, checkbutton, command, radiobutton, or sep-
              arator, or a unique  abbreviation  of  one  of  the
              above.   If  additional arguments are present, they
              specify any of the following options:

              -activebackground value
                     Specifies a background color to use for dis-
                     playing  this  entry  when it is active.  If
                     this option is specified as an empty  string
                     (the  default),  then  the  activeBackground
                     option for the overall menu is used.  If the
                     tk_strictMotif  variable  has  been  set  to
                     request strict Motif compliance,  then  this
                     option is ignored and the -background option
                     is used in its place.  This  option  is  not
                     available for separator or tear-off entries.

              -activeforeground value
                     Specifies a foreground color to use for dis-
                     playing  this  entry  when it is active.  If
                     this option is specified as an empty  string
                     (the  default),  then  the  activeForeground
                     option for the overall menu is  used.   This
                     option  is  not  available  for separator or
                     tear-off entries.

              -accelerator value
                     Specifies a string to display at  the  right
                     side  of the menu entry.  Normally describes
                     an accelerator keystroke sequence  that  may
                     be  typed to invoke the same function as the
                     menu entry.  This option  is  not  available
                     for separator or tear-off entries.

              -background value
                     Specifies a background color to use for dis-
                     playing this entry when it is in the  normal
                     state  (neither  active  nor  disabled).  If
                     this option is specified as an empty  string
                     (the  default),  then  the background option
                     for the overall menu is used.   This  option
                     is  not  available for separator or tear-off
                     entries.

              -bitmap value
                     Specifies a bitmap to display  in  the  menu
                     instead  of  a  textual label, in any of the
                     forms accepted by Tk_GetBitmap.  This option
                     overrides the -label option but may be reset
                     to an empty string to enable a textual label
                     to  be  displayed.   If  a -image option has
                     been specified, it overrides -bitmap.   This
                     option  is  not  available  for separator or
                     tear-off entries.

              -columnbreak value
                     When this option is zero, the appears  below
                     the previous entry. When this option is one,
                     the menu appears at the top of a new  column
                     in the menu.

              -command value
                     Specifies  a Tcl command to execute when the
                     menu entry is invoked.   Not  available  for
                     separator or tear-off entries.

              -compound value
                     Specifies whether the menu entry should dis-
                     play both an image  and  text,  and  if  so,
                     where the image should be placed relative to
                     the text.  Valid values for this option  are
                     bottom,  center,  left, none, right and top.
                     The default value is none, meaning that  the
                     button will display either an image or text,
                     depending on the values of  the  -image  and
                     -bitmap options.

              -font value
                     Specifies  the  font to use when drawing the
                     label or accelerator string in  this  entry.
                     If  this  option  is  specified  as an empty
                     string (the default) then  the  font  option
                     for  the  overall menu is used.  This option
                     is not available for separator  or  tear-off
                     entries.

              -foreground value
                     Specifies a foreground color to use for dis-
                     playing this entry when it is in the  normal
                     state  (neither  active  nor  disabled).  If
                     this option is specified as an empty  string
                     (the  default),  then  the foreground option
                     for the overall menu is used.   This  option
                     is  not  available for separator or tear-off
                     entries.

              -hidemargin value
                     Specifies  whether  the   standard   margins
                     should be drawn for this menu entry. This is
                     useful when creating palette with images  in
                     them,    i.e.,   color   palettes,   pattern
                     palettes, etc. 1 indicates that  the  margin
                     for  the  entry  is hidden; 0 means that the
                     margin is used.

              -image value
                     Specifies an image to display  in  the  menu
                     instead of a text string or bitmap The image
                     must have  been  created  by  some  previous
                     invocation  of  image  create.   This option
                     overrides the -label and -bitmap options but
                     may  be reset to an empty string to enable a
                     textual or bitmap  label  to  be  displayed.
                     This  option  is not available for separator
                     or tear-off entries.

              -indicatoron value
                     Available only for checkbutton and radiobut-
                     ton entries.  Value is a boolean that deter-
                     mines whether or not the indicator should be
                     displayed.

              -label value
                     Specifies  a string to display as an identi-
                     fying label in the menu entry.   Not  avail-
                     able for separator or tear-off entries.

              -menu value
                     Available  only for cascade entries.  Speci-
                     fies the path name of the submenu associated
                     with  this  entry.   The  submenu  must be a
                     child of the menu.

              -offvalue value
                     Available  only  for  checkbutton   entries.
                     Specifies  the value to store in the entry's
                     associated variable when the entry is  dese-
                     lected.

              -onvalue value
                     Available   only  for  checkbutton  entries.
                     Specifies the value to store in the  entry's
                     associated   variable   when  the  entry  is
                     selected.

              -selectcolor value
                     Available only for checkbutton and radiobut-
                     ton entries.  Specifies the color to display
                     in the indicator when the entry is selected.
                     If   the  value  is  an  empty  string  (the
                     default) then the selectColor option for the
                     menu determines the indicator color.

              -selectimage value
                     Available only for checkbutton and radiobut-
                     ton entries.  Specifies an image to  display
                     in the entry (in place of the -image option)
                     when it is selected.  Value is the  name  of
                     an  image,  which  must have been created by
                     some previous invocation  of  image  create.
                     This  option  is  ignored  unless the -image
                     option has been specified.

              -state value
                     Specifies one of three states for the entry:
                     normal,  active,  or  disabled.   In  normal
                     state the entry is displayed using the fore-
                     ground  option  for  the  menu and the back-
                     ground option from the entry  or  the  menu.
                     The  active state is typically used when the
                     pointer is over the entry.  In active  state
                     the entry is displayed using the activeFore-
                     ground option for the menu  along  with  the
                     activebackground   option  from  the  entry.
                     Disabled state means that the  entry  should
                     be  insensitive:   the default bindings will
                     refuse to activate or invoke the entry.   In
                     this  state the entry is displayed according
                     to the  disabledForeground  option  for  the
                     menu  and  the  background  option  from the
                     entry.  This option  is  not  available  for
                     separator entries.

              -underline value
                     Specifies  the  integer index of a character
                     to underline in the entry.  This  option  is
                     also  queried  by  the  default bindings and
                     used to  implement  keyboard  traversal.   0
                     corresponds  to  the  first character of the
                     text displayed in the entry, 1 to  the  next
                     character,  and so on.  If a bitmap or image
                     is displayed in the entry then  this  option
                     is  ignored.   This  option is not available
                     for separator or tear-off entries.

              -value value
                     Available  only  for  radiobutton   entries.
                     Specifies  the value to store in the entry's
                     associated  variable  when  the   entry   is
                     selected.   If an empty string is specified,
                     then the -label option for the entry as  the
                     value to store in the variable.

              -variable value
                     Available only for checkbutton and radiobut-
                     ton entries.  Specifies the name of a global
                     value  to  set  when  the entry is selected.
                     For checkbutton entries the variable is also
                     set  when  the  entry  is  deselected.   For
                     radiobutton entries, changing  the  variable
                     causes the currently-selected entry to dese-
                     lect itself.

              The add widget command returns an empty string.

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

       pathName clone newPathname ?cloneType?
              Makes a clone of the current  menu  named  newPath-
              Name.  This  clone  is a menu in its own right, but
              any changes to the  clone  are  propogated  to  the
              original menu and vice versa. cloneType can be nor-
              mal, menubar, or tearoff. Should  not  normally  be
              called  outside  of  the Tk library. See the CLONES
              section for more information.

       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  path-
              Name  (see  Tk_ConfigureInfo for information on the
              format of this list).  If option is specified  with
              no  value, then the command returns a list describ-
              ing the one named option (this list will be identi-
              cal  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 menu command.

       pathName delete index1 ?index2?
              Delete  all  of the menu entries between index1 and
              index2 inclusive.  If index2  is  omitted  then  it
              defaults  to index1.  Attempts to delete a tear-off
              menu entry are ignored (instead, you should  change
              the tearOff option to remove the tear-off entry).

       pathName entrycget index option
              Returns the current value of a configuration option
              for the entry given by index.  Option may have  any
              of the values accepted by the add widget command.

       pathName entryconfigure index ?options?
              This  command  is similar to the configure command,
              except that it applies to the options for an  indi-
              vidual  entry,  whereas  configure  applies  to the
              options for the menu as a whole.  Options may  have
              any  of  the values accepted by the add widget com-
              mand.  If options are specified, options are  modi-
              fied  as  indicated  in the command and the command
              returns an empty string.  If no options are  speci-
              fied, returns a list describing the current options
              for entry index (see Tk_ConfigureInfo for  informa-
              tion on the format of this list).

       pathName index index
              Returns the numerical index corresponding to index,
              or none if index was specified as none.

       pathName insert index type ?option value option value ...?
              Same as the  add  widget  command  except  that  it
              inserts  the  new entry just before the entry given
              by index, instead of appending to the  end  of  the
              menu.   The  type, option, and value arguments have
              the same interpretation as for the add widget  com-
              mand.   It  is  not  possible  to  insert  new menu
              entries before the tear-off entry, if the menu  has
              one.

       pathName invoke index
              Invoke  the action of the menu entry.  See the sec-
              tions on the individual entries above  for  details
              on  what  happens.   If  the menu entry is disabled
              then nothing happens.  If the entry has  a  command
              associated  with it then the result of that command
              is returned as the result of the invoke widget com-
              mand.   Otherwise  the  result  is an empty string.
              Note:  invoking a menu entry does not automatically
              unpost  the  menu;   the  default bindings normally
              take care of this before invoking the invoke widget
              command.

       pathName post x y
              Arrange  for the menu to be displayed on the screen
              at the root-window coordinates given by  x  and  y.
              These  coordinates  are  adjusted  if  necessary to
              guarantee that the entire menu is  visible  on  the
              screen.   This  command  normally  returns an empty
              string.  If the postCommand option has been  speci-
              fied,  then  its  value is executed as a Tcl script
              before posting the menu  and  the  result  of  that
              script is returned as the result of the post widget
              command.  If an error returns while  executing  the
              command, then the error is returned without posting
              the menu.

       pathName postcascade index
              Posts the submenu associated with the cascade entry
              given  by  index, and unposts any previously posted
              submenu.  If index doesn't correspond to a  cascade
              entry, or if pathName isn't posted, the command has
              no effect except to  unpost  any  currently  posted
              submenu.

       pathName type index
              Returns  the type of the menu entry given by index.
              This is the type argument passed to the add  widget
              command when the entry was created, such as command
              or separator, or tearoff for a tear-off entry.

       pathName unpost
              Unmap the window so that it is no longer displayed.
              If  a  lower-level  cascaded menu is posted, unpost
              that menu.  Returns an empty string.  This  subcom-
              mand does not work on Windows and the Macintosh, as
              those platforms have their  own  way  of  unposting
              menus.

       pathName yposition index
              Returns  a  decimal  string giving the y-coordinate
              within the menu window of the topmost pixel in  the
              entry specified by index.


MENU CONFIGURATIONS
       The  default bindings support four different ways of using
       menus:

       Pulldown Menus in Menubar
              This is the most command case. You  create  a  menu
              widget  that will become the menu bar. You then add
              cascade entries to this menu, specifying  the  pull
              down  menus  you  wish to use in your menu bar. You
              then create all of the  pulldowns.  Once  you  have
              done  this, specify the menu using the -menu option
              of the toplevel's widget command. See the  toplevel
              manual entry for details.

       Pulldown Menus in Menu Buttons
              This  is  the  compatable way to do menu bars.  You
              create one menubutton  widget  for  each  top-level
              menu,   and  typically  you  arrange  a  series  of
              menubuttons in a row in a menubar window.  You also
              create  the  top-level  menus and any cascaded sub-
              menus, and tie them together with -menu options  in
              menubuttons  and  cascade  menu  entries.  The top-
              level menu must be a child of the  menubutton,  and
              each  submenu  must  be  a  child  of the menu that
              refers to it.  Once you have done this, the default
              bindings  will  allow  users to traverse and invoke
              the tree of menus  via  its  menubutton;   see  the
              menubutton manual entry for details.

       Popup Menus
              Popup  menus  typically post in response to a mouse
              button press or keystroke.  You  create  the  popup
              menus  and any cascaded submenus, then you call the
              tk_popup procedure at the appropriate time to  post
              the top-level menu.

       Option Menus
              An  option  menu  consists  of a menubutton with an
              associated menu that allows you to  select  one  of
              several  values.  The current value is displayed in
              the menubutton and is also stored in a global vari-
              able.   Use  the  tk_optionMenu procedure to create
              option menubuttons and their menus.

       Torn-off Menus
              You create a torn-off menu by invoking the tear-off
              entry  at the top of an existing menu.  The default
              bindings will create a new menu that is a  copy  of
              the  original  menu and leave it permanently posted
              as a top-level window.  The torn-off  menu  behaves
              just the same as the original menu.


DEFAULT BINDINGS
       Tk  automatically  creates  class  bindings for menus that
       give them the following default behavior:

       [1]    When the mouse enters a menu, the entry  underneath
              the  mouse  cursor  activates;   as the mouse moves
              around the menu, the active entry changes to  track
              the mouse.

       [2]    When  the mouse leaves a menu all of the entries in
              the menu deactivate, except  in  the  special  case
              where  the  mouse  moves  from a menu to a cascaded
              submenu.

       [3]    When a button is released over a menu,  the  active
              entry  (if  any) is invoked.  The menu also unposts
              unless it is a torn-off menu.

       [4]    The Space and Return keys invoke the  active  entry
              and unpost the menu.

       [5]    If any of the entries in a menu have letters under-
              lined with with -underline  option,  then  pressing
              one of the underlined letters (or its upper-case or
              lower-case  equivalent)  invokes  that  entry   and
              unposts the menu.

       [6]    The  Escape key aborts a menu selection in progress
              without invoking any entry.  It  also  unposts  the
              menu unless it is a torn-off menu.

       [7]    The  Up  and  Down keys activate the next higher or
              lower entry in the menu.  When one end of the  menu
              is  reached,  the  active entry wraps around to the
              other end.

       [8]    The Left key moves to the next menu  to  the  left.
              If the current menu is a cascaded submenu, then the
              submenu is unposted  and  the  current  menu  entry
              becomes  the  cascade  entry in the parent.  If the
              current menu is a  top-level  menu  posted  from  a
              menubutton, then the current menubutton is unposted
              and the next menubutton  to  the  left  is  posted.
              Otherwise  the  key  has no effect.  The left-right
              order of menubuttons is determined by their  stack-
              ing  order:   Tk assumes that the lowest menubutton
              (which by default is the first one created)  is  on
              the left.

       [9]    The  Right key moves to the next menu to the right.
              If the current entry is a cascade entry,  then  the
              submenu  is  posted  and  the   current  menu entry
              becomes the first entry in the submenu.  Otherwise,
              if  the  current menu was posted from a menubutton,
              then the current menubutton  is  unposted  and  the
              next menubutton to the right is posted.

       Disabled  menu  entries  are  non-responsive:   they don't
       activate  and  they  ignore  mouse  button   presses   and
       releases.

       Several   of   the   bindings  make  use  of  the  command
       tk_menuSetFocus.  It saves the current focus and sets  the
       focus to its pathName argument, which is a menu widget.

       The behavior of menus can be changed by defining new bind-
       ings for individual widgets or  by  redefining  the  class
       bindings.


BUGS
       At present it isn't possible to use the option database to
       specify values for the options to individual entries.
