Using Longitude and Latitude Values 19

To calculate the latitude or longitude of a location, create and use the

following function:

CalcLngLat := func(dgrs, min, secs, westOrSouth) begin

local loc;

loc := dgrs / 180 + min / (180 * 60) + secs

/ (180 * 60 * 60);

loc := rinttol(loc * 0x10000000);

if westOrSouth then

loc := 0x20000000 - loc;

loc;

end;

The built-in utility functions LatitudeToString and LongitudeToString

return a string representation of an encoded integer latitude or longitude value. For

information on these functions see Newton Programmer’s Reference.

Setting the Home City 19

The SetLocation method sets the home city. It takes a single parameter

whichCity which is the same as the newCityFrame parameter of the

NewCity

method; see “Adding a City to a Newton Device” beginning on page 19-29. The

following code makes Los Angeles the home city:

GetRoot().worldClock:SetLocation( GetCityEntry

("Los Angeles") [0] );

Notes 19

This section describes the Notes API. The Notes application uses three types of

stationery: regular notes, checklists, and outlines. Figure 19-6 shows a note and a

checklist; an outline (not shown) is like the checklist without the checkboxes.
