// .NAME vtkInteractorStyleUser - provides customizable interaction routines
//
// .SECTION Description
// The most common way to customize user interaction is to write a subclass
// of vtkInteractorStyle: vtkInteractorStyleUser allows you to customize
// the interaction to without subclassing vtkInteractorStyle. This is
// particularly useful for setting up custom interaction modes in
// scripting languages such as Tcl and Python. This class allows you
// to hook into the MouseMove, ButtonPress/Release, KeyPress/Release,
// etc. events. If you want to hook into just a single mouse button,
// but leave the interaction modes for the others unchanged, you
// must use e.g. SetMiddleButtonPressMethod() instead of the more
// general SetButtonPressMethod().

// Description:
// Get the most recent mouse position during mouse motion.
// In your user interaction method, you must use this to track
// the mouse movement. Do not use GetEventPosition(), which records
// the last position where a mouse button was pressed.
vtkGetVector2Macro(LastPos,int);
// Description:
// Get the previous mouse position during mouse motion, or after
// a key press. This can be used to calculate the relative
// displacement of the mouse.
vtkGetVector2Macro(OldPos,int);
// Description:
// Test whether modifiers were held down when mouse button or key
// was pressed
vtkGetMacro(ShiftKey,int);
vtkGetMacro(CtrlKey,int);
// Description:
// Get the character for a Char event.
vtkGetMacro(Char,int);
// Description:
// Get the KeySym (in the same format as Tk KeySyms) for a
// KeyPress or KeyRelease method.

// Description:
// Get the mouse button that was last pressed inside the window
// (returns zero when the button is released).
