|
||
## ✅ 修复详情
|
||
|
||
### Bug #1: 撤销/重做功能未实现
|
||
|
||
**问题**: 用户误操作后无法撤销，体验差
|
||
|
||
**影响**: 🟡 用户体验缺失 - 专业软件必备功能
|
||
|
||
**解决方案**:
|
||
- 实现 `UndoRedoManager` 单例管理器
|
||
- 支持 50 步历史记录
|
||
- 命令模式封装操作
|
||
- 支持 6 种命令类型:
|
||
- 添加/删除元件
|
||
- 移动/旋转元件
|
||
- 添加/删除网络
|
||
|
||
**核心类**:
|
||
```dart
|
||
class UndoRedoManager {
|
||
void execute(Command command); // 执行操作
|
||
bool undo(); // 撤销
|
||
bool redo(); // 重做
|
||
void clear(); // 清空历史
|
||
|
||
bool get canUndo; // 是否可撤销
|
||
bool get canRedo; // 是否可重做
|
||
int get undoCount; // 撤销栈大小
|
||
int get redoCount; // 重做栈大小
|
||
}
|
||
```
|
||
|
||
**命令类型**:
|
||
```dart
|
||
enum CommandType {
|
||
addComponent, // 添加元件
|
||
deleteComponent, // 删除元件
|
||
moveComponent, // 移动元件
|
||
rotateComponent, // 旋转元件
|
||
addNet, // 添加网络
|
||
deleteNet, // 删除网络
|
||
}
|
||
```
|
||
|
||
**使用示例**:
|
||
```dart
|
||
final undoRedo = UndoRedoManager();
|
||
|
||
// 添加元件（带撤销支持）
|
||
final component = library.createComponentFromTemplate(template, x: 100, y: 100);
|
||
final command = CommandFactory.createAddComponent(component);
|
||
undoRedo.execute(command);
|
||
|
||
// 撤销
|
||
if (undoRedo.canUndo) {
|
||
undoRedo.undo();
|
||
}
|
||
|
||
// 重做
|
||
if (undoRedo.canRedo) {
|
||
undoRedo.redo();
|
||
}
|
||
|
||
// 快捷键支持
|
||
// Ctrl+Z = 撤销
|
||
// Ctrl+Y = 重做
|
||
```
|
||
|
||
**技术特点**:
|
||
- 命令模式封装
|
||
- 撤销栈 + 重做栈双栈设计
|
||
- 自动限制历史记录大小 (50 条)
|
||
- 执行新操作时自动清空重做栈
|
||

|
||
|
||
### Bug #2: 元件库扩展
|
||
|
||
**问题**: 只有 4 种基础元件，无法满足实际设计需求
|
||
|
||
**影响**: 🟡 功能受限 - 用户无法创建复杂电路
|
||
|
||
**解决方案**:
|
||
- 实现 `ExtendedComponentLibraryService` 扩展元件库
|
||
- 新增 8 种常用元件
|
||
- 分类管理:
|
||
- 无源元件 (电感/电位器)
|
||
- 有源元件 (二极管/NPN/PNP/MOSFET)
|
||
- 连接器 (排针)
|
||
- 开关 (SPST)
|
||
|
||
**新增元件清单**:
|
||
|
||
| 类型 | 元件 | 符号 | 引脚数 | 说明 |
|
||
|------|------|------|--------|------|
|
||
| **无源** | 电感 | L | 2 | 线圈符号 |
|
||
| | 电位器 | RV | 3 | 可调电阻 |
|
||
| **有源** | 二极管 | D | 2 | PN 结 |
|
||
| | NPN 三极管 | Q | 3 | 箭头向外 |
|
||
| | PNP 三极管 | Q | 3 | 箭头向内 |
|
||
| | N 沟道 MOSFET | Q | 3 | 场效应管 |
|
||
| **连接器** | 2P 排针 | J | 2 | 连接器 |
|
||
| **开关** | SPST 开关 | S | 2 | 单刀单掷 |
|
||
|
||
**元件总数**: 12 种 (4 基础 + 8 扩展)
|
||
|
||
**使用示例**:
|
||
```dart
|
||
final extLibrary = ExtendedComponentLibraryService();
|
||
|
||
// 获取所有元件
|
||
final allComponents = extLibrary.getAllComponents();
|
||
|
||
// 获取特定类型
|
||
final passiveComponents = extLibrary.getPassiveComponents();
|
||
final activeComponents = extLibrary.getActiveComponents();
|
||
final diode = extLibrary.getActiveComponents()
|
||
.firstWhere((c) => c.id == 'diode');
|
||
|
||
// 创建元件实例
|
||
final component = extLibrary.createComponentFromTemplate(
|
||
diode,
|
||
x: 200,
|
||
y: 150,
|
||
reference: 'D1',
|
||
value: '1N4148',
|
||
);
|
||
```
|
||
|
||
**元件图形实现**:
|
||
- 电感：3 个半圆弧线圈
|
||
- 电位器：电阻 + 滑动触点箭头
|
||
- 二极管：三角形 + 横线
|
||
- 三极管：圆圈 + 基极/集电极/发射极
|
||
- MOSFET：栅极/漏极/源极结构
|
||
- 排针：矩形 + 引脚点
|
||
- 开关：触点 + 开关臂

## 🧪 测试建议
|
||
|
||
### 测试用例 1: 撤销/重做功能
|
||
```dart
|
||
test('撤销重做功能', () {
|
||
final undoRedo = UndoRedoManager();
|
||
|
||
// 初始状态
|
||
expect(undoRedo.canUndo, false);
|
||
expect(undoRedo.canRedo, false);
|
||
|
||
// 执行操作
|
||
final component = Component(id: 'C1', ...);
|
||
final command = CommandFactory.createAddComponent(component);
|
||
undoRedo.execute(command);
|
||
|
||
// 检查状态
|
||
expect(undoRedo.canUndo, true);
|
||
expect(undoRedo.canRedo, false);
|
||
expect(undoRedo.undoCount, 1);
|
||
|
||
// 撤销
|
||
final undone = undoRedo.undo();
|
||
expect(undone, true);
|
||
expect(undoRedo.canUndo, false);
|
||
expect(undoRedo.canRedo, true);
|
||
|
||
// 重做
|
||
final redone = undoRedo.redo();
|
||
expect(redone, true);
|
||
expect(undoRedo.canUndo, true);
|
||
expect(undoRedo.canRedo, false);
|
||
});
|
||
```
|
||
|
||
### 测试用例 2: 扩展元件库
|
||
```dart
|
||
test('扩展元件库', () {
|
||
final extLibrary = ExtendedComponentLibraryService();
|
||
|
||
// 获取所有元件
|
||
final allComponents = extLibrary.getAllComponents();
|
||
expect(allComponents.length, greaterThan(10));
|
||
|
||
// 检查无源元件
|
||
final passive = extLibrary.getPassiveComponents();
|
||
expect(passive.length, greaterThan(0));
|
||
|
||
// 检查有源元件
|
||
final active = extLibrary.getActiveComponents();
|
||
expect(active.length, greaterThan(0));
|
||
|
||
// 检查特定元件
|
||
final diode = passive.firstWhere(
|
||
(c) => c.id == 'diode',
|
||
orElse: () => throw Exception('Diode not found'),
|
||
);
|
||
expect(diode.pinCount, equals(2));
|
||
expect(diode.symbol, equals('D'));
|
||
});
|
||
```
|
||
|
||
### 测试用例 3: 集成测试
|
||
```dart
|
||
test('完整编辑流程', () async {
|
||
final undoRedo = UndoRedoManager();
|
||
final library = ExtendedComponentLibraryService();
|
||
|
||
// 添加电阻
|
||
final resistor = library.getCommonComponents()[0];
|
||
final cmd1 = CommandFactory.createAddComponent(
|
||
library.createComponentFromTemplate(resistor, x: 100, y: 100),
|
||
);
|
||
undoRedo.execute(cmd1);
|
||
|
||
// 添加二极管
|
||
final diode = library.getActiveComponents()[0];
|
||
final cmd2 = CommandFactory.createAddComponent(
|
||
library.createComponentFromTemplate(diode, x: 200, y: 150),
|
||
);
|
||
undoRedo.execute(cmd2);
|
||
|
||
// 检查历史
|
||
expect(undoRedo.undoCount, 2);
|
||
|
||
// 撤销两次
|
||
undoRedo.undo();
|
||
undoRedo.undo();
|
||
expect(undoRedo.undoCount, 0);
|
||
expect(undoRedo.redoCount, 2);
|
||
|
||
// 重做一次
|
||
undoRedo.redo();
|
||
expect(undoRedo.undoCount, 1);
|
||
expect(undoRedo.redoCount, 1);
|
||
});
