Add Undo feature #22

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

Undo feature:
- Undo the latest user change to the board. Set everything (cell highlights, 
maybes, etc.) back to how it was before the "move".
- Initially support undo of just the last change.

Longer term, support:
- Undo of all user changes back to the beginning of the game.
- If the current grid is incorrect (an error has been made), support undo up to 
the move where the mistake was made.

Undo - Step backwards to beginning of game.  Redo - Step forward from previous 
undo moves.

Perhaps the Undo should step between when the user fills in answer numbers.

Undo functionality added in revision80. Undo information is however not stored 
in a saved gamed. After saving the game, the undo information is cleared. 
Probably it is not too difficult to store this information, but it will 
increase the size of the gamefile a lot.

Of course we do need to store this information! After each onPause/onResume 
(for example when rotating the screen) the undo information is lost. This is 
very unfriendly to the user. Needs more work.

Added labels: Milestone-1.96

Tested in Revision 163: Undo all the way back to beginning of game works 
correctly. Undo history is also retained when saving/reloading a game.
