user32util

Package user32util provides helper functionality for working with Windows' user32 library.

APIs

The library offers several helper functions for working with user32.

Many of these functions require that you first load the user32 DLL:

user32, err := user32util.LoadUser32DLL()
if err != nil {
	// Error handling.
}

Input listeners

• NewLowLevelMouseListener() - Starts a listener that reports on mouse input
• NewLowLevelKeyboardListener() - Starts a listener that reports on keyboard input

Send input

• SendKeydbInput() - Sends a single keyboard input
• SendMouseInput() - Sends a single mouse input
• SendInput() - Send input implements the SendInput() Windows system call
• SendHardwareInput() - Sends a single hardware input

Examples

The following examples can be found in the examples/ directory:

• moveandclickmouse - Moves the mouse and then left clicks on the new position. Takes inputs as command line arguments in x,y format. E.g., example 1221,244 460,892. Coordinates can be printed by running: example print
• readkeyboard - Reads keyboard presses and prints them to stderr
• readmouse - Reads mouse inputs and prints them to stderr
• sendinput - Sends keyboard or mouse inputs to Windows

Thank you for documenting your work, jimmycliff.
