The DateEdit interface provides visual feedback to the user via a pixamp
|
|
to indicate if the assocated GtkEntry box contains a valid date. Green
|
|
means complete and valid date. Yellow means a valid, but incomplete date.
|
|
Red means that the date is not valid, and will be viewed as a text string
|
|
instead of a date.
