  There are (i think) three ways:
	1 When the cursor type is not important, write the cursor in XOR mode.
	  delete him by writing in XOR mode again.
	2 do a blit-operation to get the current character.
	3 do it the "right" way: just put your cursor, and give an update event
	  if you want to delete him.
