CHAPTER 4
Pickers
4-8 List Pickers
Figure 4-5 Pickers can pop up from buttons, labels, and hot spots
For picker control at the bottom of a view or on the status bar, use text or picture
buttons. Elsewhere in a view, label pickers usually look best.
Position of List Pickers 4
A list picker that pops up from a button or text label should appear next to
the label or button but should not completely cover the label or button, so
users can see where the picker comes from. If a picker is too wide to fit in the
space next to the picker label or button, the picker should appear below (or
above) and flush with the label or button.
If possible, a list picker should line up with the top edge of the label or button
that makes it appear. If top alignment would cause the picker to extend past
the bottom of the screen, then the picker should line up with the bottom of
the label or button that makes it appear. A long picker (or a short screen) may
require aligning the top or bottom of the picker to the top or bottom of the
screen. Figure 4-6 illustrates proper and improper alignment of list pickers
and the labels or buttons that make them appear.
