DESCRIPTION
The 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 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 cal-
endar 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 avail-
able 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 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 showcommand.
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 com-
mand for more information on obtaining dates and their formats.
