42/* Functions to undo and redo edit commands.
43 *
44 * m_UndoList and m_RedoList handle a std::vector of PICKED_ITEMS_LIST
45 * Each PICKED_ITEMS_LIST handle a std::vector of pickers (class ITEM_PICKER),
46 * that store the list of schematic items that are concerned by the command to
47 * undo or redo and is created for each command to undo (handle also a command
48 * to redo). each picker has a pointer pointing to an item to undo or redo (in
49 * fact: deleted, added or modified), and has a pointer to a copy of this item,
50 * when this item has been modified (the old values of parameters are
51 * therefore saved)
52 *
53 * there are 3 cases:
54 * - delete item(s) command
55 * - change item(s) command
56 * - add item(s) command
57 * and 2 cases for block:
58 * - move list of items
59 * - mirror (Y) list of items
60 *
61 * Undo command
62 * - delete item(s) command:
63 * => deleted items are moved in undo list
64 *
65 * - change item(s) command
66 * => A copy of item(s) is made (a DrawPickedStruct list of wrappers)
67 * the .m_Link member of each wrapper points the modified item.
68 * the .m_Item member of each wrapper points the old copy of this item.
69 *
70 * - add item(s) command
71 * =>A list of item(s) is made. The .m_Item member of each wrapper points
72 * the new item.
73 *
74 * Redo command
75 * - delete item(s) old command:
76 * => deleted items are moved into m_tree
77 *
78 * - change item(s) command
79 * => the copy of item(s) is moved in Undo list
80 *
81 * - add item(s) command
82 * => The list of item(s) is used to create a deleted list in undo
83 * list(same as a delete command)
84 *
85 * Some block operations that change items can be undone without memorized
86 * items, just the coordinates of the transform: move list of items (undo/
87 * redo is made by moving with the opposite move vector) mirror (Y) and flip
88 * list of items (undo/redo is made by mirror or flip items) so they are
89 * handled specifically.
90 *
91 * A problem is the hierarchical sheet handling.
92 * the data associated (sub-hierarchy, undo/redo list) is deleted only
93 * when the sheet is really deleted (i.e. when deleted from undo or redo list)
94 * This is handled by its destructor.
