Replacing the Built-in Find Slip 16

Applications can replace the system-supplied Find slip with a customized version,

which is called when the application is frontmost. To implement a custom Find slip

that displays in your application, include a method named

CustomFind in the

application’s base view. This

CustomFind method must open the Find slip you

constructed and do anything else that’s appropriate, including displaying found items.

Reporting Progress to the User 16

It is strongly recommended that your status messages be consistent with those that

the built-in Newton applications display while a Find operation is in progress; for

example, you can use a message such as “Searching in appName.”

Your search method is passed a statusView parameter which is the view the system

is using to report progress. You can display a string in this view, by calling its

SetMessage method. Figure 16-10 depicts a typical status message from the Find

service.
