Specifying the List of Items for a Popup 6

You specify the item list for protoPicker, protoTextList,

protoPopUpButton, proptoPopupInPlace, and PopUpMenu in

an array. In the simplest case, this is an array of strings, but it can contain

different kinds of items:

simple string A string. You can control the pickability of a text item or add

a mark to the display by specifying the text in a frame, as

described in Table 6-1 (page 6-38).

bitmap A bitmap frame or a NewtonScript frame, as returned from

the

GetPictAsBits compile-time function. You can

control the pickability of the item or add a mark to the

display by placing the bitmap in a frame, as described in

Table 6-1 (page 6-38).

icon with string A frame that speciﬁes both a string and an icon, as described

in Table 6-2 (page 6-38).

separator line An instruction to display a line that runs the width of the

picker. To display a dashed gray line, specify the symbol

'pickSeparator. For a solid black line, specify the

symbol

'pickSolidSeparator.

two-dimensional grid

A frame describing the grid item, as described in Table 6-3

(page 6-39).

If all the items in the picker list cannot ﬁt into the view, the user can scroll the list

to see more items.

Table 6-1 describes the frame used to specify simple string and bitmap items in the

picker list.
