There are three valid formats for the dates which can be entered: [list_begin [enum]] [enum] English form MM/DD/YYYY using [arg {-format "%m/%d/%Y"}] (default) [enum] German form DD.MM.YYYY using [arg {-format "%d.%m.%Y"}] [enum] ISO form YYYY-MM-DD using [arg {-format "%Y-%m-%d"}] [list_end] [para] The datefield widget is, in fact, just an entry widget with specialized bindings. This means all the command and options for an entry widget apply equally here. [section COMMANDS] [list_begin definitions] [call [cmd ::datefield::datefield] [arg widgetpath] [opt [arg options]]] Creates and configures a date field widget. [list_end] [section OPTIONS] [list_begin definitions] [call [arg -format]] One of "%m/%d/%Y" (English, default if option left), "%d.%m.%Y" (German), or "%Y-%m-%d" (ISO). [list_end] [para] See the [cmd entry] manual entry for details on all remaining/available options. [section EXAMPLE] [example { package require datefield wm title .
