Description:

pynputrobocorpfork 5.0.0

pynput
This library allows you to control and monitor input devices.
Currently, mouse and keyboard input and monitoring are supported.
See here for the full
documentation.

Controlling the mouse
Use pynput.mouse.Controller like this:
from pynput.mouse import Button, Controller

mouse = Controller()

# Read pointer position
print('The current pointer position is {0}'.format(
mouse.position))

# Set pointer position
mouse.position = (10, 20)
print('Now we have moved it to {0}'.format(
mouse.position))

# Move pointer relative to current position
mouse.move(5, -5)

# Press and release
mouse.press(Button.left)
mouse.release(Button.left)

# Double click; this is different from pressing and releasing
# twice on macOS
mouse.click(Button.left, 2)

# Scroll two steps down
mouse.scroll(0, 2)


Monitoring the mouse
Use pynput.mouse.Listener like this:
from pynput import mouse

def on_move(x, y):
print('Pointer moved to {0}'.format(
(x, y)))

def on_click(x, y, button, pressed):
print('{0} at {1}'.format(
'Pressed' if pressed else 'Released',
(x, y)))
if not pressed:
# Stop listener
return False

def on_scroll(x, y, dx, dy):
print('Scrolled {0} at {1}'.format(
'down' if dy < 0 else 'up',
(x, y)))

# Collect events until released
with mouse.Listener(
on_move=on_move,
on_click=on_click,
on_scroll=on_scroll) as listener:
listener.join()

# ...or, in a non-blocking fashion:
listener = mouse.Listener(
on_move=on_move,
on_click=on_click,
on_scroll=on_scroll)
listener.start()
A mouse listener is a threading.Thread, and all callbacks will be invoked
from the thread.
Call pynput.mouse.Listener.stop from anywhere, raise StopException or
return False from a callback to stop the listener.
When using the non-blocking version above, the current thread will continue
executing. This might be necessary when integrating with other GUI frameworks
that incorporate a main-loop, but when run from a script, this will cause the
program to terminate immediately.

The mouse listener thread
The listener callbacks are invoked directly from an operating thread on some
platforms, notably Windows.
This means that long running procedures and blocking operations should not be
invoked from the callback, as this risks freezing input for all processes.
A possible workaround is to just dispatch incoming messages to a queue, and let
a separate thread handle them.


Handling mouse listener errors
If a callback handler raises an exception, the listener will be stopped. Since
callbacks run in a dedicated thread, the exceptions will not automatically be
reraised.
To be notified about callback errors, call Thread.join on the listener
instance:
from pynput import mouse

class MyException(Exception): pass

def on_click(x, y, button, pressed):
if button == mouse.Button.left:
raise MyException(button)

# Collect events until released
with mouse.Listener(
on_click=on_click) as listener:
try:
listener.join()
except MyException as e:
print('{0} was clicked'.format(e.args[0]))


Toggling event listening for the mouse listener
Once pynput.mouse.Listener.stop has been called, the listener cannot be
restarted, since listeners are instances of threading.Thread.
If your application requires toggling listening events, you must either add an
internal flag to ignore events when not required, or create a new listener when
resuming listening.


Synchronous event listening for the mouse listener
To simplify scripting, synchronous event listening is supported through the
utility class pynput.mouse.Events. This class supports reading single
events in a non-blocking fashion, as well as iterating over all events.
To read a single event, use the following code:
from pynput import mouse

# The event listener will be running in this block
with mouse.Events() as events:
# Block at most one second
event = events.get(1.0)
if event is None:
print('You did not interact with the mouse within one second')
else:
print('Received event {}'.format(event))
To iterate over mouse events, use the following code:
from pynput import mouse

# The event listener will be running in this block
with mouse.Events() as events:
for event in events:
if event.button == mouse.Button.right:
break
else:
print('Received event {}'.format(event))
Please note that the iterator method does not support non-blocking operation,
so it will wait for at least one mouse event.
The events will be instances of the inner classes found in
pynput.mouse.Events.


Ensuring consistent coordinates between listener and controller on Windows
Recent versions of _Windows_ support running legacy applications scaled when
the system scaling has been increased beyond 100%. This allows old applications
to scale, albeit with a blurry look, and avoids tiny, unusable user interfaces.
This scaling is unfortunately inconsistently applied to a mouse listener and a
controller: the listener will receive physical coordinates, but the controller
has to work with scaled coordinates.
This can be worked around by telling Windows that your application is DPI
aware. This is a process global setting, so _pynput_ cannot do it
automatically. Do enable DPI awareness, run the following code:
import ctypes


PROCESS_PER_MONITOR_DPI_AWARE = 2

ctypes.windll.shcore.SetProcessDpiAwareness(PROCESS_PER_MONITOR_DPI_AWARE)



Controlling the keyboard
Use pynput_robocorp.keyboard.Controller like this:
from pynput_robocorp.keyboard import Key, Controller

keyboard = Controller()

# Press and release space
keyboard.press(Key.space)
keyboard.release(Key.space)

# Type a lower case A; this will work even if no key on the
# physical keyboard is labelled 'A'
keyboard.press('a')
keyboard.release('a')

# Type two upper case As
keyboard.press('A')
keyboard.release('A')
with keyboard.pressed(Key.shift):
keyboard.press('a')
keyboard.release('a')

# Type 'Hello World' using the shortcut type method
keyboard.type('Hello World')


Monitoring the keyboard
Use pynput_robocorp.keyboard.Listener like this:
from pynput import keyboard

def on_press(key):
try:
print('alphanumeric key {0} pressed'.format(
key.char))
except AttributeError:
print('special key {0} pressed'.format(
key))

def on_release(key):
print('{0} released'.format(
key))
if key == keyboard.Key.esc:
# Stop listener
return False

# Collect events until released
with keyboard.Listener(
on_press=on_press,
on_release=on_release) as listener:
listener.join()

# ...or, in a non-blocking fashion:
listener = keyboard.Listener(
on_press=on_press,
on_release=on_release)
listener.start()
A keyboard listener is a threading.Thread, and all callbacks will be
invoked from the thread.
Call pynput_robocorp.keyboard.Listener.stop from anywhere, raise StopException
or return False from a callback to stop the listener.
The key parameter passed to callbacks is a pynput_robocorp.keyboard.Key, for
special keys, a pynput_robocorp.keyboard.KeyCode for normal alphanumeric keys, or
just None for unknown keys.
When using the non-blocking version above, the current thread will continue
executing. This might be necessary when integrating with other GUI frameworks
that incorporate a main-loop, but when run from a script, this will cause the
program to terminate immediately.

The keyboard listener thread
The listener callbacks are invoked directly from an operating thread on some
platforms, notably Windows.
This means that long running procedures and blocking operations should not be
invoked from the callback, as this risks freezing input for all processes.

a separate thread handle them.

If a callback handler raises an exception, the listener will be stopped. Since
callbacks run in a dedicated thread, the exceptions will not automatically be

To be notified about callback errors, call Thread.join on the listener
instance:

def on_press(key):
if key == keyboard.Key.esc:
raise MyException(key)

# Collect events until released
with keyboard.Listener(
on_press=on_press) as listener:
try:
listener.join()
except MyException as e:
print('{0} was pressed'.format(e.args[0]))

Please note that the iterator method does not support non-blocking operation,
so it will wait for at least one keyboard event.
The events will be instances of the inner classes found in
pynput_robocorp.keyboard.Events.


Global hotkeys
A common use case for keyboard monitors is reacting to global hotkeys. Since a
listener does not maintain any state, hotkeys involving multiple keys must
store this state somewhere.
pynput provides the class pynput_robocorp.keyboard.HotKey for this purpose. It
contains two methods to update the state, designed to be easily interoperable
with a keyboard listener: pynput_robocorp.keyboard.HotKey.press and
pynput_robocorp.keyboard.HotKey.release which can be directly passed as listener
callbacks.
The intended usage is as follows:
from pynput import keyboard

def on_activate():
print('Global hotkey activated!')

def for_canonical(f):
return lambda k: f(l.canonical(k))

hotkey = keyboard.HotKey(
keyboard.HotKey.parse('<ctrl>+<alt>+h'),
on_activate)
with keyboard.Listener(
on_press=for_canonical(hotkey.press),
on_release=for_canonical(hotkey.release)) as l:
l.join()
This will create a hotkey, and then use a listener to update its state. Once
all the specified keys are pressed simultaneously, on_activate will be
invoked.
Note that keys are passed through pynput_robocorp.keyboard.Listener.canonical before
being passed to the HotKey instance. This is to remove any modifier state
from the key events, and to normalise modifiers with more than one physical
button.
The method pynput_robocorp.keyboard.HotKey.parse is a convenience function to
transform shortcut strings to key collections. Please see its documentation for
more information.
To register a number of global hotkeys, use the convenience class
pynput_robocorp.keyboard.GlobalHotKeys:
from pynput import keyboard

def on_activate_h():
print('<ctrl>+<alt>+h pressed')

def on_activate_i():
print('<ctrl>+<alt>+i pressed')

with keyboard.GlobalHotKeys({
'<ctrl>+<alt>+h': on_activate_h,
'<ctrl>+<alt>+i': on_activate_i}) as h:
h.join()
