_________________________________________________________________

The iwidgets::calendar command creates a calendar widget for the

selection of a date, displaying a single month at a time. But- tons exist on the top to change the month in effect turning the pages of a calendar. As a page is turned, the dates for the month are modified. Selection of a date visually marks that date. The selected value can be monitored via the -command op- tion or just retrieved using the get command.

The iwidgets::calendar command creates a new Tcl command whose

name is pathName. This command may be used to invoke various op- erations 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 calendar widgets:

pathName cget option Returns the current value of the configura- tion option given by option. Option may have any of the values accepted by the iwidgets::calendar command. pathName configure ?option? ?value option value ...? Query or modify the configura- tion 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 iwid*- gets::calendar command. pathName get ?format? Returns the cur- rently selected date 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 se*- lect date Changes the currently selected date to the value speci- fied which must be in the form of a date string, an integer clock value or as the keyword now". Reference the clock command for more information on obtaining dates and their formats. Note that selecting a date does not change the month being shown to that of the date given. This chore is left to the show command. path-

Name show date Changes the currently displayed date to be that of

the date argument which must be in the form of a date string, an integer clock value or as the keyword now". Reference the clock command for more information on obtaining dates and their for- mats.
