Description

The iwidgets::calendar command creates a calendar widget for the selection  of a date, displaying a single month at a time.  Buttons 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 option or just retrieved using the get command.  

Methods

The iwidgets::calendar 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 calendar 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::calendar 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::calendar command.

pathName get ?format?

Returns the currently 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 select date

Changes the currently selected date to the value specified 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.

pathName 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 formats.
