基于我对Olive Editor的研究和分析,我将为你提供一个在History面板中添加操作时间列的实现方案。由于Olive Editor是一个开源项目,我将基于一般的Qt/C++应用程序架构来设计这个修改。
实现方案:在Olive Editor History面板中添加操作时间列
1. 分析现有架构
根据搜索结果,Olive Editor使用Qt框架开发,采用命令模式(Command Pattern)实现Undo/Redo功能。我们需要:
-
修改Command类以记录时间戳
-
更新History面板UI以显示时间列
-
确保时间格式本地化
2. 核心代码修改
2.1 修改Command基类 (command.h)
cpp
// app/core/command.h
#ifndef COMMAND_H
#define COMMAND_H#include <QString>
#include <QDateTime>
#include <QUndoCommand>class Command : public QUndoCommand
{
public:explicit Command(const QString &name = QString());virtual ~Command();// 获取命令执行时间QDateTime executionTime() const { return execution_time_; }// 获取命令名称QString commandName() const { return command_name_; }protected:// 执行命令时记录时间virtual void redo() override;// 撤销命令时记录时间virtual void undo() override;private:QString command_name_;QDateTime execution_time_;QDateTime undo_time_;// 记录是否是撤销操作bool is_undo_operation_;
};#endif // COMMAND_H
2.2 实现Command类 (command.cpp)
cpp
// app/core/command.cpp
#include "command.h"Command::Command(const QString &name): QUndoCommand(),command_name_(name),execution_time_(QDateTime::currentDateTime()),is_undo_operation_(false)
{setText(name);
}Command::~Command() = default;void Command::redo()
{QUndoCommand::redo();if (!is_undo_operation_) {execution_time_ = QDateTime::currentDateTime();}
}void Command::undo()
{QUndoCommand::undo();undo_time_ = QDateTime::currentDateTime();is_undo_operation_ = true;
}
2.3 修改History面板 (historypanel.h)
cpp
// app/panel/history/historypanel.h
#ifndef HISTORYPANEL_H
#define HISTORYPANEL_H#include <QWidget>
#include <QTableWidget>
#include <QVBoxLayout>
#include <QHeaderView>class HistoryPanel : public QWidget
{Q_OBJECTpublic:explicit HistoryPanel(QWidget *parent = nullptr);~HistoryPanel();public slots:void updateHistory();void onUndoStackChanged();private:void setupUI();void populateHistory();QString formatDateTime(const QDateTime &datetime);QTableWidget *history_table_;QVBoxLayout *main_layout_;
};#endif // HISTORYPANEL_H
2.4 实现History面板 (historypanel.cpp)
cpp
// app/panel/history/historypanel.cpp
#include "historypanel.h"
#include "app/core/command.h"
#include <QUndoStack>
#include <QUndoGroup>
#include <QApplication>HistoryPanel::HistoryPanel(QWidget *parent): QWidget(parent),history_table_(new QTableWidget(this)),main_layout_(new QVBoxLayout(this))
{setupUI();updateHistory();
}HistoryPanel::~HistoryPanel() = default;void HistoryPanel::setupUI()
{// 设置表格history_table_->setColumnCount(3);history_table_->setHorizontalHeaderLabels({tr("Action"),tr("Execution Time"),tr("Type")});// 设置表格属性history_table_->setAlternatingRowColors(true);history_table_->setSelectionBehavior(QAbstractItemView::SelectRows);history_table_->setEditTriggers(QAbstractItemView::NoEditTriggers);history_table_->horizontalHeader()->setStretchLastSection(true);history_table_->verticalHeader()->setVisible(false);// 设置列宽history_table_->setColumnWidth(0, 200); // Action列history_table_->setColumnWidth(1, 150); // Time列history_table_->setColumnWidth(2, 80); // Type列main_layout_->addWidget(history_table_);setLayout(main_layout_);// 设置面板标题setWindowTitle(tr("History"));
}void HistoryPanel::updateHistory()
{populateHistory();
}void HistoryPanel::populateHistory()
{// 获取应用程序的Undo栈QUndoGroup *undo_group = QApplication::instance()->findChild<QUndoGroup*>();if (!undo_group) return;QUndoStack *undo_stack
