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