WIDGET-SPECIFIC OPTIONS
       Name:	       childSitePos
       Class:	       Position
       Command-Line Switch:	      -childsitepos

	      Specifies the position of the child site in the entry field: n, s, e, or w.  The default is e.

       Command-Line Switch:	      -fixed

	      Restrict	entry  to  the specified number of chars.  A value of 0, which is the default, denotes no limit.  The value is the maximum
	      number of chars the user may type into the field, regardles of field width.  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.

       Class:	       Command
       Command-Line Switch:	      -focuscommand

	      Specifies a Tcl command to be executed upon determination of invalid input.  The default is bell.

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

	      Background  color  for  inside textual portion of the entry field.  The value may be given in any of the forms acceptable to Tk_Get-
	      Color.

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

	      Name of font to use for display of text in entryfield.  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 validation mechanism.	Standard character validation such as numeric, alphabetic,
	      integer, hexidecimal, real, and alphanumeric can be handled through the use of keywords.	Should more extensive validation be neces-
	      sary,  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 modified 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 entryfield prior to the latest keystroke being added.

       %W     Replaced with the entryfield widget pathname.

DESCRIPTION

       The entryfield command creates an enhanced text entry widget 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.

METHODS

       The entryfield command creates a new Tcl command whose name is pathName.  This command may be used to invoke various operations on the wid-
       get.  It has the following general form: pathName option ?arg arg ...?  Option and the args determine the exact behavior  of  the  command.
       The following commands are possible for entryfield widgets:

       See the "entry" manual entry for details on the associated methods.

WIDGET-SPECIFIC METHODS
       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 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 entryfield command.
