Simulating touch events library

makeevolution · 06-02-2021, 04:27 PM

Is there a sort of a Python library like PyAutoGUI that can simulate touch events like swiping, two-finger zoom etc.? PyAutoGUI is limited to only keyboard and mouse. Or it doesn't even have to be a Python library; something like xdo would suffice too. Thank you.

You should have asked this at python.org.

But kivy package supposedly supports touch.

You find out what the touch events are (use evtest or script your own tester), and then you open a uinput device and send those events to it.

As a demonstration of how to use it: this sends a press of the "A" key on the keyboard each time I press the "A" key on my gamepad. I can start it, switch to a text editor m, press “a” on my gamepad, and watch “a” appear in the text editor.

Code:

#!/usr/bin/env python3

import evdev

# determine this before running the program
gamepad = '/dev/input/event6'

dev = evdev.InputDevice(gamepad)


with evdev.UInput() as ui:
    for event in dev.read_loop():
        if (event.code == evdev.ecodes.BTN_A):
            ui.write(evdev.ecodes.EV_KEY, evdev.ecodes.KEY_A, event.value)
            ui.syn()
