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 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 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 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.

COMPONENTS

Name:   date
Class:  Entry

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

EXAMPLE


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