Type
Definition MRHistoryAction.h:19
This class stores history stack for undo/redo.
Definition MRHistoryStore.h:16
virtual MRVIEWER_API bool undo()
virtual MRVIEWER_API ~HistoryStore()
MRVIEWER_API void filterStack(HistoryStackFilter filteringCondition, bool deepFiltering=true)
remove some actions according to condition
boost::signals2::signal< void(const HistoryStore &store, ChangeType)> HistoryStoreChangedSignal
Definition MRHistoryStore.h:70
HistoryActionsVector * getScopeBlockPtr() const
Returns current scope ptr.
Definition MRHistoryStore.h:28
size_t getMemoryLimit() const
Returns current memory limit for this store (by default uint64 max)
Definition MRHistoryStore.h:43
void setMemoryLimit(size_t limit)
Set memory limit for this store, if history stack exceed it - old actions are removed.
Definition MRHistoryStore.h:41
virtual MRVIEWER_API bool redo()
size_t getStackPointer() const
Returns index of first redo action in stack.
Definition MRHistoryStore.h:48
const HistoryActionsVector & getHistoryStack() const
Returns full history stack.
Definition MRHistoryStore.h:46
MRVIEWER_API std::vector< std::string > getNActions(unsigned n, HistoryAction::Type type) const
Returns names of last N undo actions or first N redo actions.
static MRVIEWER_API const std::shared_ptr< HistoryStore > & getViewerInstance()
returns the instance (if any) of HistoryStore from the viewer
ChangeType
Signal is called after this store changed.
Definition MRHistoryStore.h:63
@ AppendAction
additions in scoped block does not provide signal
virtual MRVIEWER_API void appendAction(const std::shared_ptr< HistoryAction > &action)
void setSavedState()
Consider the current scene state as saved.
Definition MRHistoryStore.h:35
MRVIEWER_API std::string getLastActionName(HistoryAction::Type type) const
Returns the name of last undo or redo action (or empty string if there is no such action)
MRVIEWER_API void clear()
Clears this HistoryStore.
bool isSceneModified() const
Returns true if the current scene state does not match the saved state.
