       Class:          Command
       Command-Line Switch:           -command

              For example, if the field width is set  to  20  and
              the  fixed  value is 10, the user will only be able
              to type 10 characters into the field  which  is  20
              characters long.

       Name:           focusCommand
       Class:          Command
       Command-Line Switch:           -focuscommand

       Command-Line Switch:           -invalid

              mination of invalid input.  The default is bell.

       Name:           textBackground
       Class:          Background
       Command-Line Switch:           -textbackground

              entry field.  The value may be given in any of  the
              forms acceptable to Tk_GetColor.

       Name:           textFont
       Class:          Font
       Command-Line Switch:           -textfont

              Name  of  font to use for display of text in entry­
              field.  The value may be given in any of the  forms
              acceptable to Tk_GetFont.

       Name:           pasting
       Class:          Behavior
       Command-Line Switch:           -pasting

              Option  to  enable/disable  pasting  into the entry
              component of the entryfield.  Valid  values  are  0
              (disabled) or 1 (enabled).  Defaults to 1.

       Name:           validate
       Class:          Command
       Command-Line Switch:           -validate

              The validate option allows specification of a vali­
              dation mechanism.   Standard  character  validation
              use  of keywords.  Should more extensive validation
              be necessary, the value may contain the name  of  a
              command script.  The script should return a boolean
              value.  True for  valid,  false  for  invalid.   If
              false  is  returned,  then the procedure associated
              with the invalid option will be  invoked.   If  the
              validation  script  contains any % characters, then
              the script will not be executed directly.  Instead,
              a new script will be generated by replacing each %,
              and the character following  it,  with  information
              from  the  entryfield.   The replacement depends on
              the character following the %, as  defined  in  the
              list below.

       %c     Replaced with the current input character.

       %P     Replaced  with the contents of the entryfield modi­
              fied to  include  the  latest  keystoke.   This  is
              equivalent  to  peeking  at  the  future  contents,
              enabling rejection prior to the update.

       %S     Replaced with the current contents  of  the  entry­
              field prior to the latest keystroke being added.

       %W     Replaced with the entryfield widget pathname.



       The entryfield command creates an enhanced text entry wid­
       get with an optional associated label.  Addtional  options
       support  validation  and establishing a upper limit on the
       number of characters which may be entered in the field.


       The entryfield 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
       command.  The following commands are possible  for  entry­
       field widgets:


       delete          get            icursor         index
       insert          scan           selection       xview


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

       pathName childsite
              Returns the path name of the child site.

       pathName clear
              Clear entry widget

       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 entryfield command.


       Name:           efchildsite
       Class:          frame

              The  efchildsite  component  is the user child site
              for the entry field.  See the "frame" widget manual
              entry  for  details  on  the  efchildsite component

       Name:           entry
       Class:          entry

              user  text input and display.  See the "entry" wid­
