To Do List Compatibility 19

Version 2.0 reads and converts all 1.x To Do List soups. It does not reproduce

styling of text, because 2.0 doesn’t support styling. It does not allow shapes and

sketches in a task, so shapes and sketches are thrown away.

Because the internal structure of the 2.0 To Do List soup is completely different

from that of the 1.x version, when you transmit a 2.0 soup to a 1.x system it creates

a 1.x entry.

Using the To Do List Application 19

This section provides information about the use of the To Do List soup and

methods. To obtain a reference to the To Do List in order to send it messages, use

the following code:

GetRoot().calendar:GetToDo();

Note that future Newton devices may not include the To Do List application. You

should therefore check for the existence of the To Do List application before trying

to access it. Use the following code for this test:

if GetRoot().calendar then

if GetRoot().calendar:?GetToDo() then ...
