Overview

The Iwidgets package (also known as [incr Widgets]) is a library extension for Tcl/Tk versions 8.0 or higher, written in pure Tcl/Tk code.  It requires the compiled packages Itcl and Itk (also known as [incr Tcl] and [incr Tk], respectively).  The download location of these three library packages is

https://sourceforge.net/projects/incrtcl/files

Tablelist supports interactive cell editing with the aid of the entryfield, datefield, dateentry, timefield, timeentry, spinner, spinint, and combobox widgets from the Iwidgets package.  The steps needed for using one of these widgets for editing the cells of a given column are as follows:

  1. Register the desired widget for interactive cell editing by invoking one of the commands described in this reference page.
  2. Use the tablelist widget's columnconfigure subcommand to set the given column's -editable option to true and its -editwindow option to the value returned by the command mentioned above.  (These options are supported at cell level, too, with the aid of the cellconfigure subcommand.)

The tablelist::addIncrDateTimeWidget Command

NAME
tablelist::addIncrDateTimeWidget – Register the datefield, dateentry, timefield, or timeentry widget from the Iwidgets package for interactive cell editing
SYNOPSIS
tablelist::addIncrDateTimeWidget datefield|dateentry|timefield|timeentry ?-seconds? ?name?
DESCRIPTION
This command registers the datefield, dateentry, timefield, or timeentry widget from the Iwidgets package for interactive cell editing in tablelist widgets.  If the -seconds argument is present then the finishediting subcommand of the Tcl command associated with the tablelist widget will retrieve the content of the embedded window used for interactive cell editing as an integer clock value (in seconds), otherwise as a string.  Use this option for tablelist widgets whose internal list contains date or time information in seconds (displayed with the aid of commands given by the -formatcommand column configuration option).  The second optional argument specifies the name to be used for the datefield, dateentry, timefield, or timeentry widget as the value of the -editwindow column or cell configuration option.  It may be any string that is different from the Tk core and tile edit window names.  The default is datefield, dateentry, timefield, or timeentry, as given by the first argument.  The command returns its name argument.
When editing a cell with the aid of the temporary embedded datefield, dateentry, timefield, or timeentry widget associated with the above name, you can use the script corresponding to the -editstartcommand tablelist configuration option to set any of the widget's options, like -gmt, -iq, -int ("international" date format, supported by datefield and dateentry widgets), or -format (for timefield and timeentry widgets, with the values civilian and military).

When editing a cell with the aid of the temporary embedded spinner widget associated with the above name, you can use the script corresponding to the -editstartcommand tablelist configuration option to define validations for the widget or set any of its other options, like -decrement and -increment.
