Message:

Added begin-save-operation signal

2008-12-31 Armin Burgmeier <armin@…>

• code/operations/operations.hpp:
• code/operations/operations.cpp: Added a begin_save_operation signal, and added a boolean parameter to base operation's finished signal which indicates whether the operation was performed successfully or not. Removed the remove() function, and added finish() and fail() instead.

• code/operations/operation-open.hpp: Derive from sigc::trackable.

• code/operations/operation-save.hpp:
• code/operations/operation-save.cpp: Added get_document(), get_start_time() and derive from sigc::trackable, adapt to finish() and fail().

• code/operations/operation-new.cpp:
• code/operations/operation-open.cpp:
• code/operations/operation-delete.cpp: Adapt to finish() and fail().

• code/operations/operations.cpp (modified) (6 diffs)
