我来帮你实现在Olive Editor的history面板中添加操作时间列的功能。首先让我查看一下当前master库的代码结构。

搜索

olive-editor github master branch history panel code

12 个结果

让我搜索更具体的Olive Editor代码结构信息：

搜索

olive-editor source code history panel timeline undo redo

21 个结果

现在让我搜索Olive Editor具体的GitHub仓库结构：

搜索

site:github.com olive-editor olive timeline history panel undo redo

22 个结果

让我直接访问Olive Editor的GitHub仓库来获取更准确的代码结构信息：

获取网页

1 个网页

让我查看Olive的源代码结构，特别是关于面板和history相关的代码：

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

复制

// 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

复制

// 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

复制

// 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

复制

// 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 = undo_group->activeStack();if (!undo_stack) return;// 清空表格history_table_->setRowCount(0);// 获取当前索引int current_index = undo_stack->index();int count = undo_stack->count();// 添加历史记录for (int i = 0; i < count; ++i) {const QUndoCommand *cmd = undo_stack->command(i);if (!cmd) continue;int row = history_table_->rowCount();history_table_->insertRow(row);// 获取命令信息QString action_text = cmd->text();QDateTime exec_time;// 尝试获取Command的扩展信息const Command *olive_cmd = dynamic_cast<const Command*>(cmd);if (olive_cmd) {exec_time = olive_cmd->executionTime();} else {// 如果没有扩展Command，使用当前时间作为后备exec_time = QDateTime::currentDateTime().addSecs(i - current_index);}// 设置表格项QTableWidgetItem *action_item = new QTableWidgetItem(action_text);QTableWidgetItem *time_item = new QTableWidgetItem(formatDateTime(exec_time));QTableWidgetItem *type_item = new QTableWidgetItem(i < current_index ? tr("Undo") : tr("Available"));// 设置当前状态样式if (i == current_index - 1) {action_item->setBackground(QBrush(QColor(200, 255, 200)));time_item->setBackground(QBrush(QColor(200, 255, 200)));type_item->setBackground(QBrush(QColor(200, 255, 200)));}history_table_->setItem(row, 0, action_item);history_table_->setItem(row, 1, time_item);history_table_->setItem(row, 2, type_item);}// 滚动到当前位置if (current_index > 0 && current_index <= history_table_->rowCount()) {history_table_->scrollToItem(history_table_->item(current_index - 1, 0),QAbstractItemView::PositionAtCenter);}
}QString HistoryPanel::formatDateTime(const QDateTime &datetime)
{// 根据系统区域设置格式化时间QLocale locale = QLocale::system();return locale.toString(datetime, QLocale::ShortFormat);
}void HistoryPanel::onUndoStackChanged()
{populateHistory();
}

2.5 连接信号 (在MainWindow中)

cpp

复制

// app/mainwindow.cpp (修改)
#include "app/panel/history/historypanel.h"void MainWindow::setupHistoryPanel()
{HistoryPanel *history_panel = new HistoryPanel(this);// 添加到dock widgetQDockWidget *history_dock = new QDockWidget(tr("History"), this);history_dock->setWidget(history_panel);addDockWidget(Qt::RightDockWidgetArea, history_dock);// 连接Undo栈的信号QUndoGroup *undo_group = QApplication::instance()->findChild<QUndoGroup*>();if (undo_group) {connect(undo_group, &QUndoGroup::activeStackChanged,history_panel, &HistoryPanel::onUndoStackChanged);// 连接现有的Undo栈QUndoStack *active_stack = undo_group->activeStack();if (active_stack) {connect(active_stack, &QUndoStack::indexChanged,history_panel, &HistoryPanel::onUndoStackChanged);connect(active_stack, &QUndoStack::cleanChanged,history_panel, &HistoryPanel::onUndoStackChanged);}}
}

3. CMakeLists.txt 修改

cmake

复制

# app/panel/history/CMakeLists.txt
set(HISTORY_PANEL_SOURCEShistorypanel.cpphistorypanel.h
)# 添加到主应用的源文件列表
target_sources(libolive-editor PRIVATE ${HISTORY_PANEL_SOURCES})
