This is tricky, but I have it working.
What I do is an undo_savestate in o_move_start, to save the current
status. I disabled the undo_savestate inside o_rotate_90 if
w_current->inside_action is 1 (we are inside moving, or copying
actions). Then, if you hit ESC, i_callback_cancel calls o_undo_callback
to restore the previous state.
Now, I'm having some troubles with o_copy_end.
I do an undo_savestate in o_copy_start, as I want to do it the same way.
o_copy_end copies the object and adds it to w_current one by one. What I
want to do is:
1. Copy the objects to a new list.
2. Do an o_undo_callback to restore the previous state (as the user
can rotate the selection, the original buffer can be also rotated).
3. Add the objects from the step 1.
I changed the call the object list parameter when calling to o_*_copy by
a new list, like the example below:
Original:
new_object = (OBJECT *) o_net_copy(w_current,
w_current->page_current->
object_tail,
+ new_objects_list,
object);
New:
OBJECT *new_object_list = NULL;
new_object = (OBJECT *) o_net_copy(w_current,
new_objects_list,
object);
And after the loops, I added the new list to w_current:
s_basic_link_object (new_objects_list,
w_current->page_current->object_tail);
This doesn't seem to work... I should have missed something more...
FYI, I'm also giving a try to the multiple copy command.
Regards,
Carlos
