This class represents a panel of VCR-style buttons, including First,
Previous, Next, and Last buttons. These buttons
represent a bounded range of items that may be traversed.
The component maintains the current position within the list being
traversed. This position may be retrieved at any time via a call to the
getPosition() method. Additionally, an ActionEvent is
generated each time one of the four buttons is pressed; one of the command
strings "first", "prev", "next", or "last" is passed as the argument of the
ActionEvent to specify which button was pressed.
The First and Previous buttons are dimmed when the component
is at the "beginning" of the range, and the Next and Last
buttons are dimmed when the component is at the "end" of the range.
