win-raw-in

Enumerate raw input devices and receive input events with device ID on Windows.

Win-raw-in works by hooking into a window procedure to intercept events. This requires your application to open a window and obtain the corresponding hwnd. This can be done using ctypes or win32gui or using a high-level library such as tkinter (see example below).

For more documentation, see the 🔗 API.

Examples

List input devices

This example uses list_devices() to enumerate all raw input devices registered with Windows. Each device is an instance of RawInputDevice.

import winrawin

for device in winrawin.list_devices():
    if isinstance(device, winrawin.Mouse):
        print(f"{device.mouse_type} name='{device.path}'")
    if isinstance(device, winrawin.Keyboard):
        print(f"{device.keyboard_type} with {device.num_keys} keys name='{device.path}'")

Listen to input events

This example uses tkinter to open a window and retrieve the hwnd. Then, hook_raw_input_for_window() is used to intercept RawInputEvents.

import winrawin
import tkinter as tk

def handle_event(e: winrawin.RawInputEvent):
    if e.event_type == 'move':
        pass  # don't print mouse move events
    elif e.event_type == 'down':
        print(f"Pressed {e.name} on {e.device_type} {e.device.handle}")
    else:
        print(e)

window = tk.Tk()
winrawin.hook_raw_input_for_window(window.winfo_id(), handle_event)
window.mainloop()

This package was inspired by the keyboard package. Unfortunately, keyboard does not distinguish between multiple input devices on Windows.
