/* Functions to undo and redo edit commands.
|
|
* commmands to undo are stored in CurrentScreen->m_UndoList
|
|
* commmands to redo are stored in CurrentScreen->m_RedoList
|
|
*
|
|
* m_UndoList and m_RedoList handle a std::vector of PICKED_ITEMS_LIST
|
|
* Each PICKED_ITEMS_LIST handle a std::vector of pickers (class ITEM_PICKER),
|
|
* that store the list of schematic items that are concerned by the command to undo or redo
|
|
* and is created for each command to undo (handle also a command to redo).
|
|
* each picker has a pointer pointing to an item to undo or redo (in fact: deleted, added or modified),
|
|
* and has a pointer to a copy of this item, when this item has been modified
|
|
* (the old values of parameters are therefore saved)
|
|
*
|
|
* there are 3 cases:
|
|
* - delete item(s) command
|
|
* - change item(s) command
|
|
* - add item(s) command
|
|
* and 3 cases for block:
|
|
* - move list of items
|
|
* - mirror (Y) list of items
|
|
* - Flip list of items
|
|
*
|
|
* Undo command
|
|
* - delete item(s) command:
|
|
* => deleted items are moved in undo list
|
|
*
|
|
* - change item(s) command
|
|
* => A copy of item(s) is made (a DrawPickedStruct list of wrappers)
|
|
* the .m_Link member of each wrapper points the modified item.
|
|
* the .m_Item member of each wrapper points the old copy of this item.
|
|
*
|
|
* - add item(s) command
|
|
* =>A list of item(s) is made. The .m_Item member of each wrapper points the new item.
|
|
*
|
|
* Redo command
|
|
* - delete item(s) old command:
|
|
* => deleted items are moved in EEDrawList list, and in
|
|
*
|
|
* - change item(s) command
|
|
* => the copy of item(s) is moved in Undo list
|
|
*
|
|
* - add item(s) command
|
|
* => The list of item(s) is used to create a deleted list in undo list(same as a delete command)
|
|
*
|
|
* Some block operations that change items can be undoed without memorise items, just the coordiantes of the transform:
|
|
* move list of items (undo/redo is made by moving with the opposite move vector)
|
|
* mirror (Y) and flip list of items (undo/redo is made by mirror or flip items)
|
|
* so they are handled specifically.
