11.1 Examining objects

11.1.2 Filtering the display

The example below shows you how to create and display an instance of a CAPI object, and then limit the display in the inspector so that the only slots displayed are those you are interested in:

1. In a listener, create and display a button by typing the following:

(capi:contain (make-instance 'capi:button))

2. Choose Values > Inspect to copy the object into the inspector.

As you can see, this object has a large number of slots. You can use the Filter area to screen out everything except the available callbacks.

3. Typecallback in the Filter area and press Return.

Figure 11.5 Using filters to limit the display in the inspector

You can immediately see that the callback types that have slots in CAPI button objects. The names of the slots, together with their slot values for the object created, are displayed in the inspector.
