Go/Golang Trying to get window information via syscall. (As in EnumWindows, etc.)
问题
感谢阅读和您可能有的任何评论。
背景：
- 我已经从事UI/R&D开发（原型制作等）超过20年，刚开始进行服务器/后端开发。
- 我对Go非常陌生-不到2个月的时间-并且已经完成了GoByExample的大部分内容，并在Amazon EC2实例上设置了一个简单的工作Web服务器。
- 我使用另一种语言创建了一个UI，用于为另一个第三方应用程序提供HUD（抬头显示）-一个生成多个窗口的游戏（类似于多个窗口中运行的多个扑克桌）。
- 我将HUD连接到我创建的Go客户端。
- 我使用Go获取操作系统信息，因为第一种语言存在一些限制。
- 我想继续使用Go，因为我真的很喜欢它。
- 我使用的是Windows 7机器。
目标：
-
大局观：当用户移动一个窗口时，我希望HUD也随之移动。
-
为此，我需要关于窗口文本以“Game”开头的主窗口的信息。
-
理想情况下，应该是这样的：
windows: [ { windowHwnd:hwnd, windowText:windowText, windowX:x, windowY:y, windowWidth:width, windowHeight:height }, . . . { windowHwnd:hwnd, windowText:windowText, windowX:x, windowY:y, windowWidth:width, windowHeight:height } ]
我已经采取的步骤：
- 我已经获取并修改了github.com/AllenDang/w32，我认为它可以为Go格式化syscall。
- 当我需要从user32.go中获取未列出的函数时，我会添加它。
- 尝试使用GetForegroundWindow和GetWindowText获取结果，然后使用GetWindow(hwnd, previous)遍历所有窗口。
- 阅读了以下内容：
- syscall文档（http://golang.org/pkg/syscall/）
- syscall/dll_windows.go
- syscall/env_windows.go
- syscall/exec_windows.go
- syscall/syscall.go
- syscall/syscall_windows.go
- syscall/syscall_windows_386.go
- syscall/syscall_windows_amd86.go
- syscall/syscall_windows_test.go
- syscall/zsyscall_windows_386.go
- syscall/zsyscall_windows_amd86.go
- syscall/ztypes_windows.go
- syscall/ztypes_windows_386.go
- syscall/ztypes_windows_amd86.go
- 查找Windows Dev Center上的每个潜在窗口函数。
- 在StackExchange、Google和DuckDuckGo上搜索。
- 我可以看到有一些东西（TestEnumWindows）
- 在runtime/syscall_windows_test.go的第125行（http://golang.org/src/pkg/runtime/syscall_windows_test.go）
- 尽管这个函数在syscall_windows_test.go中不存在
问题：
- 有更好的解决方案吗？在我的无知中，我可能很容易忽视像GiveGeoffreyExactlyWhatHeWants()这样的方法。
- 我的方向正确吗？
- 在Go中是否可行？
- 前进的正确方向是什么？
- 还有其他人需要这个吗？
英文:
Thanks for reading and any comments you may have.
Context:
- I've been a UI/R&D dev (prototyping, etc.) for over 20 years and just started server/backend development.
- I'm very new to Go - less than 2 months - and have 1) run through much of GoByExample and 2) set up a primitive, working web server on an Amazon EC2 instance.
- I created a UI in another language which serves a HUD (Heads Up Display) for another 3rd party application - a game which spawns multiple windows. (Think multiple poker tables running in multiple windows.)
- I connected the HUD to a Go client I created.
- I use Go to grab OS information because of limitations in the first language.
- I want to continue to use Go because I really enjoy it.
- I'm on a Windows 7 machine.
Goal(s):
-
Big picture: When a User moves a window, I want the HUD to move with it.
-
To do this I need information about the main windows whos WindowText starts with "Game".
-
The ideal would be something like this:
windows: [ { windowHwnd:hwnd, windowText:windowText, windowX:x, windowY:y, windowWidth:width, windowHeight:height }, . . . { windowHwnd:hwnd, windowText:windowText, windowX:x, windowY:y, windowWidth:width, windowHeight:height } ]
Steps I've taken:
- I've grabbed and modified github.com/AllenDang/w32 which I think formats syscall for Go.
- When I need an unlisted function from user32.go, I add it.
- Tried using GetForegroundWindow and GetWindowText with result, then GetWindow( hwnd, previous ) to just walkthrough everything
- Read through:
- syscall docs (http://golang.org/pkg/syscall/)
- syscall/dll_windows.go
- syscall/env_windows.go
- syscall/exec_windows.go
- syscall/syscall.go
- syscall/syscall_windows.go
- syscall/syscall_windows_386.go
- syscall/syscall_windows_amd86.go
- syscall/syscall_windows_test.go
- syscall/zsyscall_windows_386.go
- syscall/zsyscall_windows_amd86.go
- syscall/ztypes_windows.go
- syscall/ztypes_windows_386.go
- syscall/ztypes_windows_amd86.go
- Every potential Window Function at Windows Dev Center
- Searched StackExchange, Google, DuckDuckGo
- I can see there's something (TestEnumWindows)
- line 125 in runtime/syscall_windows_test.go (http://golang.org/src/pkg/runtime/syscall_windows_test.go)
- Though this function doesn't exist in syscall_windows_test.go
Questions:
- Better solution? In my ignorance I could easily be overlooking some method like: GiveGeoffreyExactlyWhatHeWants()
- Am I in the right ballpark?
- Is this doable in Go?
- What's the right direction to head?
- Is this something anybody else needs?

不清楚你想要什么，但也许这个链接可以帮到你：http://play.golang.org/p/YfGDtIuuBw。它使用EnumWindows函数来查找具有特定标题的窗口。

It is not clear what you want , but perhaps http://play.golang.org/p/YfGDtIuuBw will help. It uses EnumWindows to find window with a particular title.
