MIDP Style Guide for the Java 2 Platform, Micro Edition

8.7 Dates and Times

A date field is an item that presents an editable date, time, or both to the user. All date fields are editable. Figure 8.11 shows a date field that presents a date and time to the user.

Application Developer Responsibilities	MIDP Implementor Responsibilities
Any label text Any initial value of the field Type of date field to use (date, time, or both)	Presentation of the date and time Presentation of an uninitialized date field How users enter and edit the date, time, or both

Application Developers

Consider: You can change the contents of a date field or its label as needed. Try to do it only when the form is not visible or in response to a user action. Arbitrary changes to visible screens are confusing to users.

MIDP Implementors

Consider: Determine whether you will have users edit the date and time values on the form, or on a separate screen. Figure 8.12 shows a date and a time ready for editing off the form.
