To Do List 19-25

GetToDoItemsForThisDate returns an array of tasks. Tasks are elements of

the array stored in the

topics slot of a day’s soup entry. For the structure of these

frames, see “To Do List Soup Format” (page 16-77) in Newton Programmer’s

Reference. The following code example obtains today’s tasks:

todaysTasksArray := GetRoot().calendar:GetToDo():

GetToDoItemsForThisDate(time());

GetToDoEntry

returns an array of soup entries for a specific day. Since the To

Do List stores tasks in a soup entry for each day, this array will contain an element

for each store that has a task stored under that day. The following code example

obtains today’s soup entries:

todaysEntries := GetRoot().calendar:GetToDo():

GetToDoEntry(time(),nil);

Note

The GetToDoEntry method requires that the To Do

List be open.

◆

GetToDoItemsForRange returns an array of frames for each day in the range

passed in. The following code example retrieves the tasks for the next seven days:

nextWeeksTasks := GetRoot().calendar:GetToDo():

GetToDoItemsForRange(time(), time() + 7*24*60);

There is also a To Do List method, NextToDoDate(date), which returns the

date of the next task on or after

date. This method can be useful in this context.

Checking-Off a Task 19

A tasks is marked as completed with the To Do List method SetDone. This

method requires the To Do List to be open; you can make sure the To Do List is

open by calling the Dates method

DisplayDate. The following code sample

marks off a task:

//open Dates and make it show today’s To Do List

GetRoot().calendar:Open();

GetRoot().calendar:DisplayDate(time(),'toDoList);

//get a reference to today’s tasks

todaysTasksArray := GetRoot().calendar:GetToDo():

GetToDoItemsForThisDate(time());

//find a task that says "test"

for i := 0 to length(todaysTasksArray) - 1 do

if StrEqual (todaysTasksArray[i].text, "test") then
