|
||
|
||
## 一句话总结
|
||
|
||
**主界面用 Fluent + FluentIcon,编辑器用 Material + MaterialIcon,永远不要混用,保持扁平结构。**
|
||
|
||
---
|
||
|
||
## 1. 技术栈与职责
|
||
|
||
### 1.1 库清单
|
||
|
||
| 库 | 包名 | 什么时候用 |
|
||
|---|------|----------|
|
||
| **FluentAvaloniaUI** | `FluentAvaloniaUI` | 主界面、设置页、导航 |
|
||
| **FluentIcons.Avalonia.Fluent** | `FluentIcons.Avalonia.Fluent` | 主界面图标(**首选**)|
|
||
| **FluentIcons.Avalonia** | `FluentIcons.Avalonia` | 旧图标兼容(SymbolIcon)|
|
||
| **Material.Icons.Avalonia** | `Material.Icons.Avalonia` | 编辑器图标(**仅限 ComponentEditorWindow**)|
|
||
| **Material.Avalonia** | `Material.Avalonia` | MD3 主题(**仅限 ComponentEditorWindow**)|
|
||
|
||
### 1.2 初始化顺序(App.axaml)
|
||
|
||
```xml
|
||
<Application.Styles>
|
||
<sty:FluentAvaloniaTheme /> <!-- 第 1 位:基础 Win11 风格 -->
|
||
<mi:MaterialIconStyles /> <!-- 第 2 位:全局注册 Material Icons 样式 -->
|
||
|
||
<!-- 项目自定义样式 -->
|
||
<StyleInclude Source="avares://LanMountainDesktop/Styles/FlutermotionToken.axaml" />
|
||
<StyleInclude Source="avares://LanMountainDesktop/Styles/GlassModule.axaml" />
|
||
<StyleInclude Source="avares://LanMountainDesktop/Styles/SettingsAnimations.axaml" />
|
||
<StyleInclude Source="avares://LanMountainDesktop/Styles/SettingsCardStyles.axaml" />
|
||
<StyleInclude Source="avares://LanMountainDesktop/Styles/NavigationStyles.axaml" />
|
||
</Application.Styles>
|
||
```
|
||
|
||
---
|
||
|
||
## 2. 命名空间速查表
|
||
|
||
**复制粘贴用:**
|
||
|
||
```xml
|
||
<!-- 必需 -->
|
||
xmlns="https://github.com/avaloniaui"
|
||
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
|
||
|
||
<!-- FluentAvaloniaUI 控件(主界面/设置页必需)-->
|
||
xmlns:ui="using:FluentAvalonia.UI.Controls"
|
||
|
||
<!-- Fluent Icons - 新版推荐(主界面首选)-->
|
||
xmlns:fi="using:FluentIcons.Avalonia.Fluent"
|
||
|
||
<!-- Fluent Icons - 旧版兼容(已有代码维护用)-->
|
||
<!-- xmlns:fi-legacy="using:FluentIcons.Avalonia" -->
|
||
|
||
<!-- Material Icons(仅 ComponentEditorWindow 使用)-->
|
||
<!-- xmlns:mi="clr-namespace:Material.Icons.Avalonia;assembly=Material.Icons.Avalonia" -->
|
||
|
||
<!-- Material Theme(仅 ComponentEditorWindow 使用)-->
|
||
<!-- xmlns:themes="clr-namespace:Material.Styles.Themes;assembly=Material.Styles" -->
|
||
|
||
<!-- 项目控件 -->
|
||
xmlns:local="using:LanMountainDesktop.Controls"
|
||
xmlns:comp="using:LanMountainDesktop.Views.Components"
|
||
```
|
||
|
||
---
|
||
|
||
## 3. 图标系统
|
||
|
||
### 3.1 选择决策树
|
||
|
||
```
|
||
你在写什么?
|
||
├─ 设置页面 / 主界面 / 桌面组件?
|
||
│ └─ 用 FluentIcon(fi:FluentIcon)
|
||
│ ├─ 需要 Filled/Regular 切换?→ IconVariant="Filled" 或 "Regular"
|
||
│ └─ 简单静态图标?→ 也用 FluentIcon,不用 SymbolIcon
|
||
│
|
||
├─ ComponentEditorWindow 及其子页面?
|
||
│ └─ 用 MaterialIcon(mi:MaterialIcon)
|
||
│
|
||
└─ 其他情况?
|
||
└─ 默认 FluentIcon
|
||
```
|
||
|
||
### 3.2 FluentIcon 使用方法
|
||
|
||
```xml
|
||
<fi:FluentIcon Icon="Settings" <!-- 图标名称 -->
|
||
IconVariant="Filled" <!-- Filled | Regular -->
|
||
Classes="icon-m" /> <!-- icon-s(12px) | icon-m(16px) | icon-l(20px) -->
|
||
```
|
||
|
||
**常用图标名称:**
|
||
- 导航类:`Home`, `Settings`, `Navigation`, `ArrowLeft`, `ChevronRight`, `Dismiss`
|
||
- 操作类:`Add`, `Delete`, `Edit`, `Save`, `Refresh`, `Sync`, `ArrowSync`
|
||
- 状态类:`Info`, `Warning`, `ErrorBadge`, `CheckmarkCircle`
|
||
- 外观类:`ThemeLightDark`, `ColorBackground`, `Appearance`
|
||
|
||
### 3.3 MaterialIcon 使用方法(仅限编辑器)
|
||
|
||
```xml
|
||
<mi:MaterialIcon Kind="Close" <!-- 图标名称 -->
|
||
Width="24"
|
||
Height="24"
|
||
Foreground="{DynamicResource EditorPrimaryBrush}" />
|
||
```
|
||
|
||
**常用 Kind 值:**
|
||
- 操作:`Close`, `Check`, `Pencil`, `Delete`, `Settings`, `Plus`
|
||
- 导航:`ArrowLeft`, `ArrowRight`, `Home`, `Menu`
|
||
- 系统:`Power`, `Lock`, `ExitToApp`, `Refresh`, `WeatherNight`
|
||
|
||
### 3.4 ❌ 禁止事项
|
||
|
||
```xml
|
||
<!-- ❌ 错误:同一区域混用两种图标库 -->
|
||
<StackPanel>
|
||
<fi:FluentIcon Icon="Home" /> <!-- Fluent -->
|
||
<mi:MaterialIcon Kind="Settings" /> <!-- Material -->
|
||
</StackPanel>
|
||
|
||
<!-- ❌ 错误:硬编码尺寸 -->
|
||
<fi:FluentIcon Icon="Settings" FontSize="18" />
|
||
|
||
<!-- ✅ 正确:使用预定义 class -->
|
||
<fi:FluentIcon Icon="Settings" Classes="icon-m" />
|
||
```
|
||
|
||
---
|
||
|
||
## 4. 容器嵌套规范(核心!)
|
||
|
||
### 4.1 最大深度限制
|
||
|
||
| 场景 | 最大层数 | 从哪里开始数 |
|
||
|-----|---------|------------|
|
||
| 普通页面 | **≤ 4 层** | Window/UserControl → ... → 叶子节点 |
|
||
| Popup/Dialog | **≤ 3 层** | Border → Content |
|
||
| 列表项/DataTemplate | **≤ 3 层** | Root → ... → 元素 |
|
||
| MainWindow 桌面布局 | **≤ 6 层** | 特殊允许(多层叠加需求)|
|
||
|
||
### 4.2 如何数层级?
|
||
|
||
从根元素到目标元素经过的容器标签数:
|
||
|
||
```xml
|
||
<UserControl> <!-- 层级 0(根)-->
|
||
<Border> <!-- 层级 1 -->
|
||
<Grid> <!-- 层级 2 -->
|
||
<StackPanel> <!-- 层级 3 -->
|
||
<Button> <!-- 层级 4(叶子节点)✅ OK -->
|
||
</Button>
|
||
</StackPanel>
|
||
</Grid>
|
||
</Border>
|
||
</UserControl>
|
||
```
|
||
|
||
### 4.3 推荐的标准结构
|
||
|
||
#### 结构 A:标准设置页面(3-4 层)
|
||
|
||
```xml
|
||
<UserControl>
|
||
<ScrollViewer> <!-- 层 1 -->
|
||
<StackPanel Spacing="24"> <!-- 层 2 -->
|
||
<Border Classes="settings-section-card"> <!-- 层 3 -->
|
||
<StackPanel Spacing="16"> <!-- 层 4 ✅ -->
|
||
<!-- 内容 -->
|
||
</StackPanel>
|
||
</Border>
|
||
</StackPanel>
|
||
</ScrollViewer>
|
||
</UserControl>
|
||
```
|
||
|
||
#### 结构 B:卡片/面板组件(3 层)
|
||
|
||
```xml
|
||
<Border CornerRadius="..." Padding="..."> <!-- 层 1(根)-->
|
||
<Grid RowDefinitions="Auto,*"> <!-- 层 2 -->
|
||
<Grid ColumnDefinitions="Auto,*,Auto"> <!-- 层 3a: Header -->
|
||
<fi:FluentIcon Classes="icon-l" />
|
||
<TextBlock Grid.Column="1" />
|
||
<ContentPresenter Grid.Column="2" />
|
||
</Grid>
|
||
<ContentControl Grid.Row="1" /> <!-- 层 3b: Body ✅ -->
|
||
</Grid>
|
||
</Border>
|
||
```
|
||
|
||
#### 结构 C:列表项(2-3 层)
|
||
|
||
```xml
|
||
<Border Classes="list-item"> <!-- 层 1 -->
|
||
<Grid ColumnDefinitions="Auto,*,Auto"> <!-- 层 2 -->
|
||
<Border Classes="icon-host"> <!-- 层 3a -->
|
||
<fi:FluentIcon Classes="icon-m" />
|
||
</Border>
|
||
<StackPanel Grid.Column="1" Spacing="4"> <!-- 层 3b -->
|
||
<TextBlock Classes="title" />
|
||
<TextBlock Classes="subtitle" />
|
||
</StackPanel>
|
||
<Button Grid.Column="2">...</Button> <!-- 层 3c ✅ -->
|
||
</Grid>
|
||
</Border>
|
||
```
|
||
|
||
### 4.4 ❌ 反模式:过度嵌套
|
||
|
||
```xml
|
||
<!-- ❌ 错误:7 层嵌套(实际项目中出现的反面教材)-->
|
||
<Grid> <!-- 1 -->
|
||
<Grid> <!-- 2 -->
|
||
<Border> <!-- 3 -->
|
||
<Grid> <!-- 4 -->
|
||
<Border> <!-- 5 -->
|
||
<Grid> <!-- 6 -->
|
||
<Border> <!-- 7 ❌ 太深了!-->
|
||
<Button Content="Click" />
|
||
</Border>
|
||
</Grid>
|
||
</Border>
|
||
</Grid>
|
||
</Border>
|
||
</Grid>
|
||
</Grid>
|
||
|
||
<!-- ✅ 重构后:2 层 -->
|
||
<Grid HorizontalAlignment="Center"
|
||
VerticalAlignment="Center">
|
||
<Button Content="Click"
|
||
Padding="16,8" />
|
||
</Grid>
|
||
```
|
||
|
||
### 4.5 何时可以超过限制?
|
||
|
||
只有这 3 种情况:
|
||
|
||
1. **MainWindow 桌面布局**(壁纸层 + 组件层 + 拖拽层 + 任务栏)
|
||
2. **需要独立动画层**(Transform/Opacity 动画需要单独容器)
|
||
3. **复杂 Popup 内部**
|
||
|
||
**必须加注释说明原因:**
|
||
```xml
|
||
<!--
|
||
允许深层嵌套原因:桌面渲染需要支持以下视觉层级
|
||
- DesktopWallpaperLayer(壁纸背景)
|
||
- DesktopPagesContainer(桌面分页)
|
||
- LauncherPagePanel(启动器面板)
|
||
- Canvas 拖拽层
|
||
- BottomTaskbarContainer(任务栏)
|
||
-->
|
||
<Grid x:Name="DesktopHost">
|
||
...
|
||
</Grid>
|
||
```
|
||
|
||
---
|
||
|
||
## 5. 窗口 vs UserControl vs Border
|
||
|
||
### 5.1 什么时候用什么?
|
||
|
||
| 需求 | 用什么 | 示例 |
|
||
|-----|-------|------|
|
||
| 独立窗口(有标题栏、可拖动、任务栏可见)| **Window** | SettingsWindow, ComponentEditorWindow |
|
||
| 可复用的 UI 组件块 | **UserControl** | SettingsOptionCard, ClockWidget |
|
||
| 视觉上的卡片/面板/容器 | **Border** | 设置分区卡片、弹出面板 |
|
||
|
||
### 5.2 ❌ 禁止:窗口套窗口
|
||
|
||
```csharp
|
||
// ❌ 错误:在 XAML 中实例化另一个 Window
|
||
// <local:SettingsWindow Visibility="Visible" />
|
||
|
||
// ✅ 正确:通过代码显示独立窗口
|
||
var settings = new SettingsWindow { Owner = this };
|
||
settings.Show();
|
||
```
|
||
|
||
### 5.3 ❌ 禁止:把 Window 当 UserControl 用
|
||
|
||
```xml
|
||
<!-- ❌ 错误:MainWindow 内部嵌入了一个本应是独立窗口的东西 -->
|
||
<Window x:Class="MainWindow">
|
||
<Grid>
|
||
<Border x:Name="ComponentLibraryWindow" <!-- 这看起来像窗口,但不应该是 Window -->
|
||
Width="620"
|
||
Height="320"
|
||
CornerRadius="36">
|
||
<!-- 组件库内容 -->
|
||
</Border>
|
||
</Grid>
|
||
</Window>
|
||
```
|
||
|
||
**如果它不是真正的操作系统窗口,就用 Border 或 UserControl。**
|
||
|
||
---
|
||
|
||
## 6. 颜色与资源使用规范
|
||
|
||
### 6.1 必须使用 DynamicResource
|
||
|
||
```xml
|
||
<!-- ❌ 错误:硬编码颜色 -->
|
||
<TextBlock Foreground="#FF1D1B20" />
|
||
<Border Background="#FFF3EDF7" />
|
||
<Button Background="#FF6750A4" />
|
||
|
||
<!-- ✅ 正确:使用动态资源 -->
|
||
<TextBlock Foreground="{DynamicResource AdaptiveTextPrimaryBrush}" />
|
||
<Border Background="{DynamicResource AdaptiveSurfaceRaisedBrush}" />
|
||
<Button Background="{DynamicResource AccentBrush}" />
|
||
```
|
||
|
||
### 6.2 常用资源键速查
|
||
|
||
| 资源键 | 用途 | 示例场景 |
|
||
|--------|------|---------|
|
||
| `AdaptiveTextPrimaryBrush` | 主要文本 | 标题、正文 |
|
||
| `AdaptiveTextSecondaryBrush` | 次要文本 | 描述文字、提示 |
|
||
| `AdaptiveSurfaceRaisedBrush` | 抬高表面 | 卡片背景、面板 |
|
||
| `AdaptiveSurfaceOverlayBrush` | 覆盖层 | 遮罩、弹窗背景 |
|
||
| `AccentBrush` | 强调色 | 主按钮、选中态 |
|
||
| `AppFontFamily` | 应用字体 | 全局字体设置 |
|
||
|
||
### 6.3 圆角 Token(强制!)
|
||
|
||
```xml
|
||
<!-- ❌ 错误:硬编码圆角 -->
|
||
<Border CornerRadius="8" />
|
||
<Button CornerRadius="12" />
|
||
|
||
<!-- ❌ 错误:桌面组件根容器用了非组件级 Token -->
|
||
<Border CornerRadius="{DynamicResource DesignCornerRadiusMd}" />
|
||
|
||
<!-- ✅ 正确 -->
|
||
<!-- 桌面组件(Widget)根容器必须且只能用这个 -->
|
||
<Border CornerRadius="{DynamicResource DesignCornerRadiusComponent}" />
|
||
|
||
<!-- 内部元素按层级选择 -->
|
||
<Border CornerRadius="{DynamicResource DesignCornerRadiusSm}" /> <!-- 小 -->
|
||
<Border CornerRadius="{DynamicResource DesignCornerRadiusMd}" /> <!-- 中 -->
|
||
<Border CornerRadius="{DynamicResource DesignCornerRadiusLg}" /> <!-- 大 -->
|
||
```
|
||
|
||

|
||
|
||
## 7. FluentAvaloniaUI 控件用法
|
||
|
||
### 7.1 NavigationView(设置页导航)
|
||
|
||
```xml
|
||
<ui:NavigationView x:Name="RootNav"
|
||
PaneDisplayMode="Auto" <!-- 自动折叠 -->
|
||
OpenPaneLength="283" <!-- Win11 标准宽度 -->
|
||
IsSettingsVisible="False" <!-- 隐藏默认设置按钮 -->
|
||
IsBackButtonVisible="False"
|
||
SelectionChanged="OnNavChanged">
|
||
|
||
<ui:NavigationView.Resources>
|
||
<!-- 移除默认背景色 -->
|
||
<SolidColorBrush x:Key="NavigationViewContentBackground" Color="Transparent" />
|
||
<SolidColorBrush x:Key="NavigationViewContentGridBorderBrush" Color="Transparent" />
|
||
</ui:NavigationView.Resources>
|
||
|
||
<Grid Margin="12,0,16,16">
|
||
<ui:Frame x:Name="ContentFrame" />
|
||
</Grid>
|
||
</ui:NavigationView>
|
||
```
|
||
|
||
### 7.2 Frame(页面导航容器)
|
||
|
||
```xml
|
||
<ui:Frame x:Name="ContentFrame" />
|
||
```
|
||
|
||
```csharp
|
||
// C# 代码中导航
|
||
ContentFrame.Navigate(typeof(SettingsHomePage));
|
||
// 或绑定
|
||
ContentFrame.SourcePageType = typeof(SettingsHomePage);
|
||
```
|
||
|
||
### 7.3 InfoBar(内联通知条)
|
||
|
||
```xml
|
||
<ui:InfoBar Title="发现新版本"
|
||
Message="v2.0.0 可用"
|
||
Severity="Informational" <!-- Informational | Warning | Error | Success -->
|
||
IsOpen="True"
|
||
ActionButtonText="立即更新"
|
||
ActionButtonClick="OnUpdateClick"
|
||
CloseButtonClick="OnDismissClick" />
|
||
```
|
||
|
||
### 7.4 ContentDialog(模态对话框)
|
||
|
||
```csharp
|
||
var dialog = new ContentDialog
|
||
{
|
||
Title = "确认删除",
|
||
Content = "确定要删除吗?此操作不可撤销。",
|
||
PrimaryButtonText = "删除",
|
||
CloseButtonText = "取消",
|
||
DefaultButton = ContentDialogButton.Primary
|
||
};
|
||
|
||
var result = await dialog.ShowAsync(this);
|
||
if (result == ContentDialogResult.Primary)
|
||
{
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 8. Material.Avalonia 使用规范(严格限制!)
|
||
|
||
### 8.1 ⚠️ 只能在这里用
|
||
|
||
**✅ 允许:**
|
||
- `ComponentEditorWindow.axaml`
|
||
- ComponentEditorWindow 的子编辑页面
|
||
|
||
**❌ 禁止:**
|
||
- MainWindow
|
||
- SettingsWindow
|
||
- NotificationWindow
|
||
- 任何桌面组件(Widget)
|
||
- 任何其他地方
|
||
|
||
### 8.2 如何在 ComponentEditorWindow 中启用
|
||
|
||
```xml
|
||
<Window ...>
|
||
<Window.Resources>
|
||
<!-- MD3 色板(仅此窗口有效)-->
|
||
<SolidColorBrush x:Key="EditorPrimaryBrush" Color="#FF6750A4" />
|
||
<SolidColorBrush x:Key="EditorSurfaceContainerBrush" Color="#FFF3EDF7" />
|
||
<SolidColorBrush x:Key="EditorOnPrimaryBrush" Color="#FFFFFFFF" />
|
||
</Window.Resources>
|
||
|
||
<Window.Styles>
|
||
<!-- 加载 Material 主题(只影响此窗口)-->
|
||
<themes:CustomMaterialTheme BaseTheme="Light"
|
||
PrimaryColor="#6750A4"
|
||
SecondaryColor="#625B71" />
|
||
|
||
<!-- 项目自定义覆盖 -->
|
||
<StyleInclude Source="avares://LanMountainDesktop/Styles/ComponentEditorThemeResources.axaml" />
|
||
</Window.Styles>
|
||
</Window>
|
||
```
|
||
|
||
### 8.3 MD3 组件示例
|
||
|
||
#### FAB 按钮(浮动操作按钮)
|
||
|
||
```xml
|
||
<Button x:Name="SaveFAB"
|
||
HorizontalAlignment="Right"
|
||
VerticalAlignment="Bottom"
|
||
Margin="28"
|
||
Width="64" Height="64"
|
||
Background="{DynamicResource EditorPrimaryBrush}"
|
||
Foreground="{DynamicResource EditorOnPrimaryBrush}"
|
||
CornerRadius="{DynamicResource DesignCornerRadiusComponent}"
|
||
Click="OnSaveClick">
|
||
<mi:MaterialIcon Kind="Check" Width="32" Height="32" />
|
||
</Button>
|
||
```
|
||
|
||
#### Top App Bar(顶栏)
|
||
|
||
```xml
|
||
<Border Background="{DynamicResource EditorTopAppBarBackgroundBrush}"
|
||
Padding="24,16">
|
||
<Grid ColumnDefinitions="Auto,*,Auto">
|
||
<mi:MaterialIcon Kind="Widgets"
|
||
Width="28" Height="28"
|
||
Foreground="{DynamicResource EditorPrimaryBrush}" />
|
||
<TextBlock Grid.Column="1"
|
||
FontSize="20" FontWeight="SemiBold"
|
||
Text="组件编辑器"
|
||
Margin="16,0,0,0" />
|
||
<Button Grid.Column="2" Click="OnCloseClick">
|
||
<mi:MaterialIcon Kind="Close" Width="24" Height="24" />
|
||
</Button>
|
||
</Grid>
|
||
</Border>
|
||
```
|
||
|
||

|
||
|
||
## 9. 实战代码模板
|
||
|
||
### 模板 1:新建设置页面
|
||
|
||
文件位置:`Views/Settings/YourPageName.axaml`
|
||
|
||
```xml
|
||
<UserControl xmlns="https://github.com/avaloniaui"
|
||
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
|
||
xmlns:fi="using:FluentIcons.Avalonia.Fluent"
|
||
xmlns:local="using:LanMountainDesktop.Controls"
|
||
x:Class="LanMountainDesktop.Views.Settings.YourPageName">
|
||
|
||
<ScrollViewer Padding="24,0,24,24">
|
||
<StackPanel Spacing="24">
|
||
|
||
<!-- 分区卡片 -->
|
||
<Border Classes="settings-section-card">
|
||
<StackPanel Spacing="16">
|
||
|
||
<!-- 分区标题 -->
|
||
<Grid ColumnDefinitions="Auto,*" ColumnSpacing="12">
|
||
<fi:FluentIcon Icon="YourSectionIcon"
|
||
IconVariant="Filled"
|
||
Classes="icon-l" />
|
||
<TextBlock Grid.Column="1"
|
||
Classes="settings-section-title"
|
||
Text="分区标题" />
|
||
</Grid>
|
||
|
||
<!-- 选项卡 1 -->
|
||
<local:SettingsOptionCard Icon="OptionIcon1"
|
||
Title="选项标题"
|
||
Title="选项描述">
|
||
<local:SettingsOptionCard.ActionContent>
|
||
<ToggleSwitch IsChecked="{Binding YourProperty, Mode=TwoWay}" />
|
||
</local:SettingsOptionCard.ActionContent>
|
||
</local:SettingsOptionCard>
|
||
|
||
<!-- 选项卡 2 -->
|
||
<local:SettingsOptionCard Icon="OptionIcon2"
|
||
Title="另一个选项"
|
||
Title="描述信息" />
|
||
|
||
</StackPanel>
|
||
</Border>
|
||
|
||
</StackPanel>
|
||
</ScrollViewer>
|
||
</UserControl>
|
||
```
|
||
|
||
**嵌套检查:** ScrollViewer(1) > StackPanel(2) > Border(3) > StackPanel(4) > Items(5) ✅ (因为有 ScrollViewer 容器,5 层可接受)
|
||
|
||
### 模板 2:新建桌面小组件
|
||
|
||
文件位置:`Views/Components/YourWidget.axaml`
|
||
|
||
```xml
|
||
<UserControl xmlns="https://github.com/avaloniaui"
|
||
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
|
||
x:Class="LanMountainDesktop.Views.Components.YourWidget">
|
||
|
||
<Border Classes="desktop-widget-root"
|
||
CornerRadius="{DynamicResource DesignCornerRadiusComponent}"
|
||
Padding="16,12">
|
||
<Grid RowDefinitions="Auto,*" RowSpacing="8">
|
||
|
||
<!-- 标题区 -->
|
||
<TextBlock x:Name="TitleTextBlock"
|
||
FontSize="14"
|
||
FontWeight="SemiBold" />
|
||
|
||
<!-- 内容区 -->
|
||
<ContentControl Grid.Row="1" />
|
||
|
||
</Grid>
|
||
</Border>
|
||
</UserControl>
|
||
```
|
||
|
||
**嵌套检查:** Border(1) > Grid(2) > Elements(3) ✅ 完美!
|
||
|
||
### 模板 3:新建独立窗口
|
||
|
||
```xml
|
||
<Window xmlns="https://github.com/avaloniaui"
|
||
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
|
||
xmlns:ui="using:FluentAvalonia.UI.Controls"
|
||
xmlns:fi="using:FluentIcons.Avalonia.Fluent"
|
||
x:Class="LanMountainDesktop.Views.YourWindow"
|
||
Width="800"
|
||
Height="600"
|
||
MinWidth="400"
|
||
MinHeight="300"
|
||
CanResize="True"
|
||
SystemDecorations="BorderOnly"
|
||
Background="Transparent"
|
||
Title="窗口标题">
|
||
|
||
<Grid RowDefinitions="Auto,*">
|
||
|
||
<!-- 自定义标题栏 -->
|
||
<Border Height="48"
|
||
Padding="12,0"
|
||
PointerPressed="OnTitleBarPressed">
|
||
<Grid ColumnDefinitions="Auto,*,Auto">
|
||
<fi:FluentIcon Icon="WindowIcon"
|
||
IconVariant="Filled"
|
||
Classes="icon-m" />
|
||
<TextBlock Grid.Column="1"
|
||
Text="{Binding Title}"
|
||
VerticalAlignment="Center" />
|
||
<Button Grid.Column="2"
|
||
Click="OnCloseClick">
|
||
<fi:FluentIcon Icon="Dismiss" IconVariant="Regular" />
|
||
</Button>
|
||
</Grid>
|
||
</Border>
|
||
|
||
<!-- 主内容区 -->
|
||
<ContentControl Grid.Row="1"
|
||
Content="{Binding Content}" />
|
||
|
||
</Grid>
|
||
</Window>
|
||
```
|
||
|
||
**嵌套检查:** Grid(1) > Border(2) > Grid(3) > Elements(4) ✅

## 10. AI 编码检查清单
|
||
|
||
### 写代码前问自己
|
||
|
||
- [ ] 这个文件是设置页/主界面?→ 用 Fluent + FluentIcon
|
||
- [ ] 这个文件是 ComponentEditorWindow?→ 用 Material + MaterialIcon
|
||
- [ ] 我用了正确的命名空间吗?(见第 2 节速查表)
|
||
- [ ] 图标用了 Classes="icon-s/m/l" 而非硬编码 FontSize 吗?
|
||
|
||
### 写完代码后检查
|
||
|
||
- [ ] 数一下最大嵌套深度(见第 4.2 节)
|
||
- [ ] 有没有硬编码颜色值?(应该都用 DynamicResource)
|
||
- [ ] 有没有硬编码 CornerRadius?(应该用 DesignCornerRadiusXxx)
|
||
- [ ] 有没有在同一区域混用 FluentIcon 和 MaterialIcon?
|
||
- [ ] 是不是不小心写了 `<local:SomeWindow>` 在另一个 Window 里?
|
||
- [ ] 是不是连续写了 Border > Grid > Border > Grid 可以合并?
|
||
|
||
### 如果审查别人代码
|
||
|
||
- [ ] 发现窗口套窗口了吗?
|
||
- [ ] 发现超过 4 层的无意义嵌套了吗?(没有注释说明原因的话)
|
||
- [ ] 发现 Fluent 和 Material 控件混在同一区域了吗?
|
||
- [ ] 发现应该用 DynamicResource 的地方硬编码了吗?

## 附录:常见错误快速修复
|
||
|
||
| 错误现象 | 问题原因 | 修复方法 |
|
||
|---------|---------|---------|
|
||
| 图标不显示或大小不对 | 用了错误的命名空间或硬编码尺寸 | 改用 `fi:FluentIcon` + `Classes="icon-m"` |
|
||
| 圆角在设置里改了但没生效 | 硬编码了 CornerRadius | 改用 `{DynamicResource DesignCornerRadiusComponent}` |
|
||
| 深色模式下颜色刺眼 | 硬编码了颜色值 | 改用 `{DynamicResource AdaptiveTextPrimaryBrush}` 等 |
|
||
| 设置页风格和其他窗口不一致 | 混用了 Material 控件 | 统一用 FluentAvaloniaUI 控件 |
|
||
| 性能差/渲染慢 | 嵌套太深(>6 层)| 扁平化结构,合并多余容器 |
|
||
| 弹窗显示位置/大小异常 | 把 Window 当成 UserControl 嵌套了 | 改为代码中 `.Show()` 显示 |
