1. A method for moving a graphic object, wherein the method comprises:

  • A. determining a module X and a movement direction corresponding to a graphic object to be moved;

    B. moving the module X by one unit in the movement direction, determining whether the module X overlaps partially with another module, and if not so, then taking the status after the movement as a movement result and ending the process;

    otherwise, restoring the module X to its original location and determining and mirror-inverting a smallest mirrored area including the module X; and

    C. determining whether the mirror-inverted module X can be further moved in the movement direction, and if not so, then indicating a movement failure and ending the process;

    otherwise, moving the module X by one unit in the movement direction, determining whether the module X overlaps partially with another module, and if not so, taking the status after the movement as a movement result and ending the process;

    otherwise, repeating the step C.
