The iwidgets::timefield command creates an enhanced text entry widget for the purpose of time entry with various degrees of built-in intelligence.


The iwidgets::timefield 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 timefield 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::timefield 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::timefield command.

pathName get ?format?

Returns the current contents of the timefield 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 times and their  formats.

pathName isvalid

Returns a boolean indication of the validity of the currently displayed time value.  For example, 12:59:59 is valid whereas 25:59:59 is invalid.

pathName show time

Changes the currently displayed time to be that of the time  argument.  The time may be specified either as a string, an integer clock value or the keyword "now" (the default).  Reference the clock command for more information on obtaining times and their formats.
