Step 7: Add a Message Prompter part
You've added user-interface parts to the window for AlarmClockView. Now add a Message Prompter part to get a message box when the alarm clock "rings."
Adding the part
To add a Message Prompter part:
1. Select 
(Prompters category) and 
(Message Prompter part).
(Prompters category) and (Message Prompter part). 2. Click on the free-form surface.
The Composition Editor now displays:
Changing the settings
Now, customize the part by changing its settings:
1. Double-click on the Message Prompter part to open its settings view window.
2. For iconType, select a type that beeps when the message box is displayed, such as XmICONWARNING.
3. In the Title field, type a title such as:
Get Moving!
4. Don't add a messageString, because the user will specify the message in the Alarm Clock application.
5. For buttonType select XmOK, because the message box only needs one button on it.
6. Select OK.
