// .NAME vtkButtonWidget - activate an n-state button
// .SECTION Description
// The vtkButtonWidget is used to interface with an n-state button. That is
// each selection moves to the next button state (e.g., moves from "on" to
// "off"). The widget uses modulo list traversal to transition through one or
// more states. (A single state is simply a "selection" event; traversal
// through the list can be in the forward or backward direction.)
//
// Depending on the nature of the representation the appearance of the button
// can change dramatically, the specifics of appearance changes are a
// function of the associated vtkButtonRepresentation (or subclass).
//
// .SECTION Event Bindings
// By default, the widget responds to the following VTK events (i.e., it
// watches the vtkRenderWindowInteractor for these events):
// <pre>
// LeftButtonPressEvent - select button
// LeftButtonReleaseEvent - end the button selection process
// </pre>
//
// Note that the event bindings described above can be changed using this
// class's vtkWidgetEventTranslator. This class translates VTK events
// into the vtkButtonWidget's widget events:
// <pre>
// vtkWidgetEvent::Select -- some part of the widget has been selected
// vtkWidgetEvent::EndSelect -- the selection process has completed
// </pre>
//
// In turn, when these widget events are processed, the vtkButtonWidget
// invokes the following VTK events on itself (which observers can listen for):
// <pre>
// vtkCommand::StateChangedEvent (on vtkWidgetEvent::EndSelect)
// </pre>
