Functions

func EnumWindows

func EnumWindows(enumFunc uintptr, lparam uintptr) (err error)

func FindWindow

func FindWindow(className, windowName string) (syscall.Handle, error)

FindWindow finds hwnd by name. This can't find all types of windows. For dialogs and controls, use FindWindowEx and FindWindowFromEnum instead.

hwnd, _ := w32find.FindWindow("", "Your window title")

func FindWindowEx

func FindWindowEx(hwndParent, hwndChildAfter syscall.Handle, className, windowName string) (syscall.Handle, error)

FindWindowEx finds a child window. This can be used to find controls inside a window.

h2, err2 := w32find.FindWindowEx(h1, 0, "", "Your child window title")

func FindWindowExW

func FindWindowExW(hwndParent, hwndChildAfter syscall.Handle, className, windowName *uint16) syscall.Handle

func FindWindowFromEnum

func FindWindowFromEnum(title string) (syscall.Handle, error)

FindWindowFromEnum finds a window from user32!EnumWindows(). This can be used to find dialogs.

h1, err1 := w32find.FindWindowFromEnum("Your parent window title")

func FindWindowW

func FindWindowW(className, windowName *uint16) syscall.Handle

func GetWindowText

func GetWindowText(hwnd syscall.Handle, str *uint16, maxCount int32) (len int32, err error)
