Member Data Documentation

◆ flags

uint UndoType::flags

Information for the generic undo system to refine handling of this specific undo type.

Definition at line 145 of file BKE_undo_system.hh.

◆ name

const char* UndoType::name

◆ next

UndoType* UndoType::next

Definition at line 110 of file BKE_undo_system.hh.

◆ poll

bool(* UndoType::poll) (struct bContext *C)

When NULL, we don't consider this undo type for context checks. Operators must explicitly set the undo type and handle adding the undo step. This is needed when tools operate on data which isn't the primary mode (eg, paint-curve in sculpt mode).

◆ prev

UndoType * UndoType::prev

Definition at line 110 of file BKE_undo_system.hh.

◆ step_decode

void(* UndoType::step_decode) (bContext *C, Main *bmain, UndoStep *us, eUndoStepDir dir, bool is_final)

Definition at line 131 of file BKE_undo_system.hh.

◆ step_encode

bool(* UndoType::step_encode) (bContext *C, Main *bmain, UndoStep *us)

Definition at line 130 of file BKE_undo_system.hh.

◆ step_encode_init

void(* UndoType::step_encode_init) (bContext *C, UndoStep *us)

None of these callbacks manage list add/removal.

Note that 'step_encode_init' is optional, some undo types need to perform operations before undo push finishes.

◆ step_foreach_ID_ref

void(* UndoType::step_foreach_ID_ref) (UndoStep *us, UndoTypeForEachIDRefFn foreach_ID_ref_fn, void *user_data)

Definition at line 140 of file BKE_undo_system.hh.

◆ step_free

void(* UndoType::step_free) (UndoStep *us)

Note: When freeing all steps, free from the last since BKE_UNDOSYS_TYPE_MEMFILE will merge with the next undo type in the list.

Definition at line 138 of file BKE_undo_system.hh.

◆ step_size

size_t UndoType::step_size

The size of the undo struct 'inherited' from UndoStep for that specific type. Used for generic allocation in BKE's undo_system.cc.

Definition at line 150 of file BKE_undo_system.hh.
