You can use the protos described in this section to present pop-up views to the user

for setting or choosing speciﬁc types of values. The Newton System Software

provides the following pop-up protos for date, time, and location values:

■ The protoDatePopup allows the user to choose a single date. For information

about the slots and methods for this proto, see “protoDatePopup” (page 5-63) in

Newton Programmer’s Reference. Figure 6-23 shows an example of a

protoDatePopup.

■ The protoDatePicker allows the user to choose a single date when the date

is likely to be relatively close to the current date. Changing the year is not easily

done with this proto. For information about the slots and methods for this proto,

see “protoDatePicker” (page 5-64) in Newton Programmer’s Reference.

Figure 6-24 shows an example of a

protoDatePicker.
