    00028 OgreCursor.h  -
    00029     The Cursor is an non-visual object that contains a the XYZ values that
    00030     are modified by a InputReader.
    00031     An InputReader creates and contains a Cursor object that it uses when it
    00032     is set to buffered input (using the EventQueue).
    00033
    00034     To get a graphical representation of the cursor, a CursorGuiElement is
    00035     used, which is a MouseMotionListener to the Cursor.
