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

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

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

              Specifies a Tcl command to be executed upon detection of a Return key press event.

       Name:           gmt
       Class:          GMT
       Command-Line Switch:           -gmt

              Determines whether the date is calculated relative to Greenwich Mean Time. Accepts  a  boolean
              value. The default is no.

       Name:           int
       Class:          DateFormat
       Command-Line Switch:           -int

              Used to specify international date formats.  This option must be a boolean value.  When set to
              true, the date is formatted as YYYY-MM-DD.  When set to false, it is formatted as  MM/DD/YYYY.
              Note  that  this format is driven by the 'clock scan' command and that YYYY-MM-DD is supported
              in Tk 8.4 or later.  The default is no.

       Name:           iq
       Class:          Iq
       Command-Line Switch:           -iq

              Specifies the level of intelligence to be shown in the actions taken by the  datefield  during
              the  processing  of  keypress  events.  Valid settings include high, average, and low.  With a
              high iq,the date prevents the user from typing in an invalid date.  For example, if  the  cur-
              rent  date  is 05/31/1997 and the user changes the month to 04, then the day will be instantly
              modified for them to be 30.  In addition, leap years are fully taken into account.  With aver-age average
              age  iq, the month is limited to the values of 01-12, but it is possible to type in an invalid
              day.  A setting of low iq instructs the widget to do no validity checking at all  during  date
              entry.   With  both  average and low iq levels, it is assumed that the validity will be deter-mined determined
              mined at a later time using the date's isvalid command.

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

              Specifies one of two states for the datefield: normal or disabled.  If the datefield  is  dis-abled disabled
              abled then input is not accepted.  The default is normal.

       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_GetColor.

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

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

DESCRIPTION
       The  iwidgets::datefield  command creates an enhanced text entry widget for the purpose of date entry
       with various degrees of built-in intelligence.



METHODS
       The iwidgets::datefield 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.  The following commands are possible
       for datefield widgets:

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 iwidgets::datefield 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 iwidgets::datefield command.

       pathName get ?format?
              Returns the current contents of the datefield in a format of string or  as  an  integer  clock
              value  using  the  -string and -clicks format options respectively.  The default is by string.
              Reference the clock command for more information on obtaining dates and their formats.

       pathName isvalid
              Returns a boolean indication of the validity of the currently displayed date value.  For exam-ple, example,
              ple, 03/03/1960 is valid whereas 02/29/1997 is invalid.

       pathName show date
              Changes  the currently displayed date to be that of the date argument.  The date may be speci-fied specified
              fied either as a string, an integer clock value or the keyword  "now".   Reference  the  clock
              command for more information on obtaining dates and their formats.


COMPONENTS
       Name:           date
       Class:          Entry

              The  date component provides the entry field for date input and display.  See the "entry" wid-get widget
              get manual entry for details on the date component item.


EXAMPLE
               package require Iwidgets 4.0
               proc returnCmd {} {
                 puts [.df get]
               }

               iwidgets::datefield .df -command returnCmd
               pack .df -fill x -expand yes -padx 10 -pady 10
