This also removes the GROUP/UNGROUP-specific undo actions. This also fixes a bunch of undo bugs when duplicating group members, creating pins, etc. This also fixes some undo bugs when dividing wires etc. This also fixes some bugs with new sch items not being created within an entered group.

/* Functions to undo and redo edit commands.
|
|
*
|
|
* 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 into m_tree
|
|
*
|
|
* - 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.
|
