SetProcessDPIAware + +```go +procSetProcessDPIAware.Call() +``` + +否则 200% DPI 下 `GetSystemMetrics` 返回逻辑像素 1620x1080，壁纸只占左上 1/4。必须在最开头调用。 + +### 2. 找到正确 WorkerW + +```go +// 1. 发送 0x052C 消息让 Progman 创建新 WorkerW +procSendMessageTimeoutW.Call(progman, 0x052C, 0, 0, 0x0000, 1000, ...) + +// 2. 找 SHELLDLL_DefView +shellDefView := FindWindowExW(progman, 0, "SHELLDLL_DefView", 0) + +// 3. 找 SHELLDLL_DefView 之后的 WorkerW ← 这是关键 +workerw := FindWindowExW(progman, shellDefView, "WorkerW", 0) +``` + +要点：必须是 `SHELLDLL_DefView` **之后**的那个 WorkerW，不是随便一个 WorkerW。 + +### 3. SetParent 嵌入 + +```go +procSetParent.Call(wvHwnd, workerw) +``` + +### 4. 去边框 (GWL_STYLE) + +```go +const GWL_STYLE = ^uintptr(15) // -16, 不是 ^uintptr(0)>>1-19 +procSetWindowLongPtrW.Call(wvHwnd, GWL_STYLE, + uintptr(WS_POPUP|WS_VISIBLE|WS_CLIPCHILDREN)) +``` + +**GWL_STYLE = -16 的正确写法是 `^uintptr(15)`**。常见错误 `^uint32(0)>>1-19` = `0x7FFFFFEC`（大正数），根本不是 -16，SetWindowLongPtrW 不会报错但修改的是错误的属性。 + +**切忌写成 -4**（那是 GWL_WNDPROC），会覆盖窗口过程指针导致 exit 127 崩溃。 + +### 5. 自定义消息循环替代 wv.Run() + +```go +// 不用 wv.Run()，用标准 GetMessage 循环 +var m winMsg +for { + r, _, _ := procGetMessageW.Call(uintptr(unsafe.Pointer(&m)), 0, 0, 0) + if r == 0 { return } + procTranslateMessage.Call(uintptr(unsafe.Pointer(&m))) + procDispatchMessageW.Call(uintptr(unsafe.Pointer(&m))) +} +``` + +**为什么不能 wv.Run()**: go-webview2 的 Run() 内部用 `GetAncestor(GA_ROOT)` 判断消息路由。SetParent 到 WorkerW 后，窗口根祖先变成 Progman(explorer)，Run() 的消息循环异常结束 → WebView2 停止渲染，壁纸冻结。 + +### 6. 延迟嵌入 + 直接调用 + +```go +go func() { + time.Sleep(3 * time.Second) // 等 WebView2 初始化完成 + wvHwnd := uintptr(wv.Window()) + procSetParent.Call(wvHwnd, workerw) // user32 调用，跨线程安全 + procSetWindowLongPtrW.Call(...) + procMoveWindow.Call(...) +}() +``` + +不能用 `wv.Dispatch` 嵌入——它依赖 `wv.Run()` 驱动，自定义消息循环不驱动它 → Dispatch 回调永不执行。SetParent/MoveWindow/SetWindowLongPtr 是 Win32 API，跨线程安全，直接调即可。 + +--- + +## 踩坑记录 + +### explorer 桌面层损坏 + +反复 SetParent / kill 进程会把桌面 WorkerW 层搞坏（连之前能跑的产物都不显示）。 + +**症状**: 枚举找不到全屏 WorkerW、SHELLDLL_DefView 直接挂在 Progman 下。 + +**修复**: 重启 explorer.exe 重建干净结构。 + +### OpenGL 不可见 + +在干净环境下（explorer 重启后 + 正确 WorkerW + SwapBuffers 双缓冲 + 渲染像素验证 RGBA=0,255,0,255 正确），OpenGL 窗口仍不显示，透出系统壁纸。 + +**根因**: Germanium 上桌面壁纸层的子窗口必须经 DirectComposition 合成。OpenGL SwapBuffers 走传统 GDI blt 路径，DWM 不合成。 + +#### 尝试过的方案及结果 + +| 方案 | 结果 | 说明 | +|------|------|------| +| SwapBuffers（双缓冲） | ❌ 帧缓冲正确但不可见 | glReadPixels 确认 RGBA=0,255,0,255 | +| SetParent 前初始化 GL | ❌ | GL context 在 SetParent 后可能与 DC 断联 | +| SetParent 后初始化 GL | ❌ | 调换顺序无改善 | +| WS_CHILD 样式 + SetWindowPos | ❌ | 窗口样式调整不影响 DWM 合成 | +| glReadPixels → GDI SetDIBitsToDevice | ❌ | GDI blit 也不被 DWM 合成 | +| 去掉 PFD_DOUBLEBUFFER | ❌ | 单缓冲也无改善 | + +**结论**: WorkerW 子窗口的呈现链路被 DWM 接管，只有通过 DirectComposition 提交的图面才能上屏。GDI BitBlt/SetDIBitsToDevice、OpenGL SwapBuffers 全部走传统路径，DWM 不处理。 + +#### Go + OpenGL 踩坑汇总 + +1. **Go syscall 不能传浮点参数**: Windows x64 用 XMM 寄存器传 float，但 Go 的 `syscall.SyscallN` 只设 GPR 寄存器 (RCX/RDX/R8/R9)。`glClearColor(1,0,0,1)` 实际传入 `(0,0,0,0)`。**必须用指针变体**: `glUniform1fv`, `glUniform2fv`, `glClearBufferfv`。 + +2. **glClearBufferfv 错误 1280 (GL_INVALID_ENUM)**: 第一个参数用了 `GL_COLOR_BUFFER_BIT` (0x4060)，正确值是 `GL_COLOR` (0x1800)。改用 `glClear(GL_COLOR_BUFFER_BIT)` 更简单。 + +3. **wglGetProcAddress 不能加载 GL 1.1 函数**: `glGetError`, `glClear`, `glFlush` 等是 GL 1.1，直接从 `opengl32.dll` 导出，`wglGetProcAddress` 返回 0。GL 1.2+ 才用 `wglGetProcAddress`。 + +4. **PFD 结构体必须 40 字节**: Go 结构体布局要与 C 的 `PIXELFORMATDESCRIPTOR` 完全一致。关键字段: `Size` 和 `Version` 是 `uint16`，`Flags` 是 `uint32`，中间 20 个 `byte`，末尾 3 个 `uint32`。 + +5. **shader 用 `layout(location=N)`**: `glGetUniformLocation` 在 Intel GPU 上崩溃 (0xC0000005)。用 GLSL 430 的 `layout(location=N)` 绑定 uniform 位置避免调用此函数。 + +6. **wglCreateContext vs wglCreateContextAttribsARB**: 前者创建遗留 context，后者创建 Core Profile。`wglCreateContext` 在 Intel 驱动上也能拿到 GL 4.6 context。 + +### WebView2 降资源方案（未实现） + +wallpaper.html 里把 `RENDER_SCALE` 从 1.0 降到 0.5，canvas 渲染分辨率减半再拉伸。GPU 子进程内存可从 425MB 大幅降低，视觉略糊。比重写 DComp 省事得多。 + +--- + +## 项目结构 + +``` +u-desktop/ +├── main.go # Go 层: WebView2 创建 + WorkerW 嵌入 + 系统托盘 +├── wallpaper.html # 渲染层: WebGL 极光 + 天气组件 + 星座运势 +├── backup-opengl/ # OpenGL 方案备份（已确证不可行） +├── go.mod / go.sum +└── docs/ + └── wallpaper-embedding.md # 本文档 +``` + +## 依赖 + +``` +github.com/jchv/go-webview2 # WebView2 绑定 +github.com/getlantern/systray # 系统托盘 +golang.org/x/sys/windows # Win32 API +``` + +## 开机自启 + +注册表 `HKCU\Software\Microsoft\Windows\CurrentVersion\Run\UDesktopWallpaper` = `u-desktop.exe 路径` + +## 构建 & 运行 + +```bash +go build -o u-desktop.exe . +.\u-desktop.exe +``` + +托盘图标右键: 暂停/继续、星座设置(子菜单)、城市选择(点击天气文字)、退出。全屏应用自动暂停渲染。 + +--- + +## 2025-05-25 踩坑追加 + +### IP 定位在国内不准 / 永远显示上海 + +**症状**: 天气城市始终显示上海，IP 定位不准。 + +**根因链路**: +1. `ipify.org` 在国内被墙 → 获取公网 IP 失败 +2. `fallbackLocation()` 按预置城市列表顺序逐个试天气 API +3. 上海排在第一位，且天气 API 返回成功 → 固定为上海 +4. 即便 ipify 能用，和风天气 GeoAPI 对部分 IP 段（如移动 `111.60.x.x`）返回 404 + +**修复**: IP 定位改为 `myip.ipip.net`（国内可用，直接返回城市名文本），从文本提取城市名匹配预置列表。保留 ipify + QWeather GeoAPI 作为降级源。优先级：`localStorage 手动选择` > `ipip.net` > `QWeather GeoAPI` > `fallback 逐城尝试` + +### WebGL requestAnimationFrame 导致电脑卡顿 + +**症状**: 启动后系统明显卡顿。 + +**根因**: WebGL 极光 shader 以 60fps 全屏渲染持续占 GPU。壁纸场景动画是慢波效果，不需要高帧率。 + +**修复**: 帧率限制为 15fps，视觉无差异，GPU 占用降 ~75%。 + +### 壁纸层 WebView 无法弹出 Modal 交互 + +**症状**: 托盘菜单"星座设置"点击无反应。 + +**根因链路**: +1.
