Go lang - Get current mouse cursor position with RobotGo

问题

我是一个Go语言的初学者，我想解决一个小任务：将鼠标光标的当前坐标打印到控制台，并在鼠标移动时更新坐标。为此，我使用了robotgo库，通过以下命令下载它："go get github.com/go-vgo/robotgo"，然后使用"go get -u github.com/go-vgo/robotgo"进行更新，并使用import "github.com/go-vgo/robotgo"导入它。以下是我编写的代码：

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"github.com/go-vgo/robotgo"
  6. )
  8. func main() {
  9. 	for {
  10. 		x, y := robotgo.GetMousePos()
  11. 		fmt.Printf("当前位置 X=%d, Y=%d", x, y)
  12. 		if x == 540 && y == 960 {
  13. 			fmt.Println("光标在中心位置")
  14. 		}
  16. 		robotgo.Move(x, y)
  17. 	}
  18. }

但是我遇到了错误：

  1. # github.com/robotn/gohook

更新 2023年3月16日 问题已通过完全删除库及其依赖项，然后重新安装解决。

英文:

I'm a beginner in Go and I want to solve a small task: to print the current coordinates of the mouse cursor to the console and update them if the mouse moves. For this, I took the library robotgo, downloaded it using "go get github.com/go-vgo/robotgo", then "go get -u github.com/go-vgo/robotgo", and imported it using import "github.com/go-vgo/robotgo". Here's the code I wrote:

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"github.com/go-vgo/robotgo"
  6. )
  8. func main() {
  9. 	for {
  10. 		x, y := robotgo.GetMousePos()
  11. 		fmt.Printf("Current position X=%d, Y=%d", x, y)
  12. 		if x == 540 && y == 960 {
  13. 			fmt.Println("Cursor @center")
  14. 		}
  16. 		robotgo.Move(x, y)
  17. 	}
  18. }

But I'm getting errors:

  1. # github.com/robotn/gohook
  2. C:\CODING\SDK\GO-PATH\pkg\mod\github.com\robotn\gohook@v0.40.0\event.go:51:10: undefined: addEvent

  4. C:\CODING\SDK\GO-PATH\pkg\mod\github.com\robotn\gohook@v0.40.0\event.go:75:18: undefined: KeyHold
  5. C:\CODING\SDK\GO-PATH\pkg\mod\github.com\robotn\gohook@v0.40.0\event.go:83:18: undefined: KeyUp
  6. C:\CODING\SDK\GO-PATH\pkg\mod\github.com\robotn\gohook@v0.40.0\event.go:95:22: undefined: KeyUp

UPD 16.03.2023 problem was solved by completely removing the library and its dependencies, and then reinstalling it.

对于Windows系统，可以使用系统API：GetCursorPos

  1. //go:build windows
  3. package main
  5. import (
  6. 	"fmt"
  7. 	"syscall"
  8. 	"unsafe"
  9. )
  11. func main() {
  12. 	userDll := syscall.NewLazyDLL("user32.dll")
  13. 	getCursorPosProc := userDll.NewProc("GetCursorPos")
  14. 	type POINT struct {
  15. 		X, Y int32
  16. 	}
  17. 	var pt POINT
  18. 	_, _, eno := syscall.Syscall(getCursorPosProc.Addr(), 1, uintptr(unsafe.Pointer(&pt)), 0, 0)
  19. 	if eno != 0 {
  20. 		fmt.Println(eno)
  21. 	}
  22. 	fmt.Printf("[cursor.Pos] X:%d Y:%d\n", pt.X, pt.Y)
  23. }

请注意，这是一个使用Go语言编写的示例代码，用于获取鼠标光标的位置。它使用了Windows系统的user32.dll库中的GetCursorPos函数。

英文:

For windows, use the system API :GetCursorPos

  1. //go:build windows
  3. package main
  5. import (
  6. 	"fmt"
  7. 	"syscall"
  8. 	"unsafe"
  9. )
  11. func main() {
  12. 	userDll := syscall.NewLazyDLL("user32.dll")
  13. 	getWindowRectProc := userDll.NewProc("GetCursorPos")
  14. 	type POINT struct {
  15. 		X, Y int32
  16. 	}
  17. 	var pt POINT
  18. 	_, _, eno := syscall.SyscallN(getWindowRectProc.Addr(), uintptr(unsafe.Pointer(&pt)))
  19. 	if eno != 0 {
  20. 		fmt.Println(eno)
  21. 	}
  22. 	fmt.Printf("[cursor.Pos] X:%d Y:%d\n", pt.X, pt.Y)
  23. }
