  public Object clone()

clones a text object by making an exact copy of this text object with values equal to the original values, except that the starting and ending points of the newly cloned text are translated by a value of TRANSLATE_X and TRANSLATE_Y defined in the ObjBaseClass.java.

Returns:

a cloned text object.

clone in class Object

  public boolean mouseDown(int x,
                           int y)

event handler for mouse down while drawing

Parameters:

x - x value

y - y value

Returns:

true

  public boolean mouseUp(int x,
                         int y)

event handler for mouse up when drawing objects. This event is not relevant to this class of text string objects. The event is not implemented though it's being declared due to compliance to the interface DrawObject.

Parameters:

x - x value

y - y value

true

  public void send()

  public boolean mouseDrag(int x,
                           int y)

event handler for mouse drag when drawing the objects. Not relevant and hence not implemented though declared due to compliance to the interface DrawObject.

Parameters:

x - x value

y - y value

Returns:

true
