Buttons on the J2ME Wireless Toolkit emulator
SUN's J2ME Wireless Toolkit emulator exhibits several qualities that you are likely to find
in real devices:
•
The device has a small screen size and limited input capabilities. (It's not as small as
the earlier J2ME Wireless Toolkit 1.x emulators, which included emulated devices with
96×128 and 96×54-pixel screens.)
•
Two
soft buttons
are available. A soft button does not have a fixed function. Generally,
the function of the button at any given time is shown on the screen near the button. In
MIDlets, the soft buttons are used for commands.
•
Navigation buttons
are provided to allow the user to browse through lists or other sets
of choices.
•A
select button
allows the user to make a choice after moving to it with the navigation
buttons. (Think “Yes, that's my final answer.”)
