of the form MM/DD/YYYY can be entered.

get apply equally here.

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 exam-
ple, if the current 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 average 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 determined 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 disabled 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_Get-
Color.
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 intel-
ligence.
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 com-
mand. 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 iwid-
gets::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 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 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 for-
mat 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 example, 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 specified 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
