UndoRedo的简单实现

#include "context.h" conText::conText() :m_pEnditOperation(nullptr) { } conText::~conText() { } void conText::Undo() { m_UndoRedo.Undo(); } void conText::Redo() { m_UndoRedo.Redo(); } void conText::begin() { m_pEnditOperation = new EnditOperation(this); } void conText::end(int type) { if (type == 1) { m_UndoRedo.AddUndo(m_pEnditOperation); } else if (type == 2) { m_UndoRedo.AddRedo(m_pEnditOperation); } } void conText::HisTest(int type, std::vector<int> value) { if (m_pEnditOperation !=NULL) { m_pEnditOperation->Revalue(value); } else { EnditOperation *pEnditOperation = new EnditOperation(this); pEnditOperation->Revalue(value); if (type == 1) { m_UndoRedo.AddUndo(pEnditOperation); } else if (type == 2) { m_UndoRedo.AddRedo(pEnditOperation); } } } void conText::UpData(std::vector<int> value) { m_data = value; } void conText::add(int value) { m_data.push_back(value); HisTest(1, m_data); } void conText::pop() { m_data.pop_back(); HisTest(2, m_data); }
