CHAPTER 22. EXTENDED STREAM INPUT

=> :port [Init Arg]
The :port initarg is used to specify the port with which the pointer is associated.

=> standard-pointer [Class]
The instantiable class that implements a pointer.

=> pointer-port pointer [Generic Function]
Returns the port with which the pointer pointer is associated.

=> pointer-sheet pointer [Generic Function]
=> (setf pointer-sheet) sheet pointer [Generic Function]
Returns (or sets) the sheet over which the pointer pointer is located.

=> pointer-buttons pointer [Generic Function]
Returns the state of the buttons of the pointer pointer. This is represented in the same as
pointer-event-button.

=> pointer-position pointer [Generic Function]
Returns the x and y position of the pointer pointer as two values.

=> (setf* pointer-position) x y pointer [Generic Function]
Sets the x and y position of the pointer pointer to the specified position.

=> pointer-cursor pointer [Generic Function]
=> (setf pointer-cursor) cursor pointer [Generic Function]
A pointer object usually has a visible cursor associated with it. These functions return (or set)
the cursor associated with the pointer pointer.

22.5 Pointer Tracking

=> tracking-pointer (sheet &key pointer multiple-windows transformp context-type highlight) &bodybody [Macro]
The tracking-pointer macro provides a general means for running code while following the
position of a pointing device, and monitoring for other input events. The programmer supplies
code (the clauses in body) to be run upon the occurrence of any of the following types of events:

Motion of the pointer
Motion of the pointer over a presentation
