Step 2: Add parts to AlarmClockView
When completed, 
AlarmClockView has the following user interface: 

To define this user interface, first, add two push buttons to the empty window in the Composition Editor: 
1.	Select 

(Buttons category) and 

(Push Button part) from the parts palette. After you select them, the status line along the bottom of the editor shows: 
 Category: Buttons Part: Push Button 
2.	Click on the Sticky checkbox in the lower left of the editor so it shows a check mark. You now can add multiple push buttons to the empty window without having to select the Push Button part again. 
3.	Click on the lower-left and then on the lower-right of the window. This adds the push buttons. 

 4.	Click on 

(the Selection tool) on the Tool bar to disarm the 
Sticky.
