       Name:           clickTime
       Class:          ClickTime
       Command-Line Switch:           -clicktime

              Interval  time,  in  msec, used to determine that a
              single mouse click has occurred. Used to post  menu
              on  a  "quick"  mouse  click.   Note: changing this
              value may cause the  sigle-click  functionality  to
              not work properly.  The default is 150 msec.

       Name:           command
       Class:          Command
       Command-Line Switch:           -command

              Specifies  a  Tcl command procedure to be evaluated
              following a  change  in  the  current  option  menu

       Name:           cyclicOn
       Class:          CyclicOn
       Command-Line Switch:           -cyclicon

              Turns  on/off  the 3rd mouse button capability. The
              value may be specified in any of the forms  accept­
              able  to  Tcl_GetBoolean.   This feature allows the
              cycles through the  menu  in  reverse  order.   The
              default is true.

       Name:           popupCursor
       Class:          Cursor
       Command-Line Switch:           -popupcursor

              Specifies   the  mouse  cursor  to  be used for the
              popup menu.  The value may have any of  the   forms
              acceptable to Tk_GetCursor.

       Name:           state
       Class:          State
       Command-Line Switch:           -state

              Specified  one  of  two  states for the optionmenu:
              normal, or disabled.  If  the  optionmenu  is  dis­
              abled, then option menu selection is ignored.

       Name:           width
       Class:          Width
       Command-Line Switch:           -width

              Specifies a fixed size for the menu button label in
              any of the forms acceptable  to  Tk_GetPixels.   If
              the text is too small to fit in the label, the text
              is clipped.  Note: Normally, when  a  new  list  is
              created,  or  new  items  are  added to an existing
              list, the menu button label  is  resized  automati­
              cally.   Setting  this  option overrides that func­



       The optionmenu command creates an option menu widget  with
       options  to  manage  it.   An option menu displays a frame
       containing a label and a button.  A pop-up menu will allow
       for the value of the button to change.


       The  optionmenu  command  creates  a new Tcl command whose
       name is pathName.  This command may be used to invoke var­
       ious  operations on the widget.  It has the following gen­
       eral form:

              pathName option ?arg arg ...?

       Option and the args determine the exact  behavior  of  the
       argument an indicator of which entry of the option menu to
       operate  on.   These indicators are called indexes and may
       be specified in any of the following forms:

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

       end         Indicates the bottommost entry  in  the  menu.
                   If  there are no entries in the menu then zero
                   is returned.

       select      Returns the numerical index of  the  currently
                   selected  option  menu  entry.   If no entries
                   exist in the menu, then -1 is returned.

       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  option  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 optionmenu


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

       pathName delete first ?last?
              Delete all of the option menu entries between first
              and last inclusive.  If last  is  omitted  then  it
              Disable  the  option menu entry specified by index.
              Disabling a menu item will prevent  the  user  from
              being able to select this item from the menu.  This
              only effects the state of the item in the menu,  in
              other  words,  should  the  item  be  the currently
              selected item, the programmer  is  responsible  for
              determining  this  condition and taking appropriate

       pathName enable index
              Enable the option menu entry  specified  by  index.
              Enabling a menu item allows the user to select this
              item from the menu.

       pathName get ?first? ?last?
              If  no  arguments  are  specified,  this  operation
              returns  the  currently  selected option menu item.
              Otherwise, it returns the name  of  the  option  at
              index  first,  or  a range of options between first
              and last.

       pathName index index
              Returns the numerical index corresponding to index.

       pathName insert index string ?string?
              Insert  an item, or list of items, into the menu at
              location index.

       pathName select index
              Select an item from the option menu to be displayed
              as the currently selected item.

       pathName sort mode
              Sort  the  current  menu  in  either  ascending, or
              descending  order.   The  values   increasing,   or
              decreasing are also accepted.
