/* Functions to undo and redo edit commands.
|
|
* commands to undo are stored in CurrentScreen->m_UndoList
|
|
* commands 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 2 cases for block:
|
|
* - move list of items
|
|
* - mirror (Y) 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 GetDrawItems() 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 undone without memorized
|
|
* items, just the coordinates 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.
|
|
*
|
|
* A problem is the hierarchical sheet handling.
|
|
* the data associated (sub-hierarchy, undo/redo list) is deleted only
|
|
* when the sheet is really deleted (i.e. when deleted from undo or redo list)
|
|
* This is handled by its destructor.
