I'm currently working on a Selenium program that requires I open up a system file-selector dialog. Unfortunately it's impossible to circumvent this by just sending keys to a webpage attribute, as I have to select a button with no file-acceptance, which automatically opens up the file-selector dialog.
I believe the only solution is to send keys through the system itself to the file selector. Unfortunately, the method I'm currently using (below) requires that the window be active for it to receive the keys.
I used the pynput library in order to send the keys on my first iteration. The pynput documentation for keyboards can be found here:
https://pynput.readthedocs.io/en/latest/keyboard.html
from pynput.keyboard import Key, Controller
import os, time
file = "723583.jpg" #this is a local directory file
keyboard = Controller()
keyboard.type(os.path.abspath(file))
time.sleep(5) #Please ignore the bad style of using these sleeps
keyboard.press(Key.enter) #They're just for testing
time.sleep(3)
keyboard.press(Key.enter)
time.sleep(3)
On other Stackoverflow questions, I've found solutions for Windows computers (e.g. using win32), though I haven't been able to find anything for MacOS, which I'm currently using, or an equivalent multi-platform solution. Does anybody know how I might be able to send keys to a background application as such?

I have been trying to figure out how to automate disabling a particular device as a speaker while keeping it as a microphone. PowerShell would not disable it as a PnP device unless I wanted to disable the entire object. So I have resorted to python and using keys. I have been able to open the sound panel. I've also been able to maneuver between windows. But when I send the down key to enter into the selection menu (as you would typing) it doesn't do anything. I've tried pyautogui and pynput. The general format so far during testing is:
import pyautogui
from pynput.keyboard import Key, Controller
import os, win32gui, time, win32api
os.system('cmd /k "control mmsys.cpl sounds"')
#hwnd = win32gui.FindWindow("none", "Sounds")
#win32gui.SetForegroundWindow(hwnd)
time.sleep(3)
pyautogui.press(
'pagedown')```
I'm creating an application in which users can select a specific part of the screen to screenshot, which will then get processed. The (naive) way that I'm doing this currently is using the pyautogui library to simulate the windows shortcut for that:
def take_screenshot():
time.sleep(1)
# Windows hotkey for selective manual screenshot
pyautogui.hotkey('win', 'shift', 's')
time.sleep(8)
# return retrieved screenshot from clipboard
return ImageGrab.grabclipboard()
This is obviously a very hacky solution, as i am just halting the program for some amount of time until the use has selected a specific area using the screenshot. But i'm wondering is what the best way is to handle this? I want to wait until the user is done taking a screenshot to process it, so i was thinking there is a way to listen to windows events to know whether a screenshot is still being taken?
How can I send keystrokes and mouse movements to a specific running program through its PID. I've used both pywinauto and pynput, and they work great, but I want to send keys to a program that is not in focus. I found this question: How to I send keystroke to Linux process in Python by PID? but it never explains what filePath is a path to.
If you could help solve for this example, that would be great! I want to send the "d" key to an open Minecraft tab for 10 seconds, and then send the "a" key for the next 10 seconds and stop. I would need this to be able to run in the background, so it could not send the keys to the computer as a whole, but only to the Minecraft tab. I am on Windows 10 by the way.
Any help would be appreciated!
Pretty sure you won't be able to, at least not easily let me explain a little bit how all of this works.
Lets start with the hardware and os, the OS has certain functions to read the input you give the computer. This input goes into a "pipe", the OS is reading input, and putting into the pipe, on the other side of the pipe there may be an application running, or it may not. The OS typically manages this (which app to put on the pipe listening) by defining which app/window is active. Apps access this pipe with the API given by the OS, they read the input and decide on it.
The libraries you cited above, change the values of the keyboard and mouse, in other words, they make the OS read other values, not the real ones, then the OS puts them in the "pipe", and are read by the app that is listening on the pipe (the one active). Some apps have their own API's for this, but I would guess Minecraft doesn't. If they don't have an API, what can you do? well, as I said, nothing easy, first of all "hacking" the app, in other words change it to listen to some other input/output rather than the one given by the OS, (this would be you making your own API). The other one would be you changing the OS, which would also be extremely hard, but maybe a tiny bitty easier. It also depends on your OS, I think Microsoft does offer input injection api's
So, simple options, first, run a VM with a GUI and use pywinauto, pyautogui, etc. The other option would be if you can run it in the browser, do so, and use something like Selenium to automate the input.
Quick note, why does selenium works and the browser can read input in the background? Easy, it's not, it just executes the code it would execute if it would have read the input! javascript, cool isn't
With ahk you can do this with Python+AutoHotkey
pip install ahk
pip install "ahk[binary]"
from ahk import AHK
from ahk.window import Window
ahk = AHK()
win = Window.from_pid(ahk, pid='20366')
win.send('abc') # send keys directly to the window
Note that some programs may simply ignore inputs when they are not in focus. However, you can test this works in general even when not in focus by testing with a program like notepad
Full disclosure: I author the ahk library.
I am trying to write e2e tests for a Slack bot and while logging in via browser it always asks whether I'd like to use the Slack desktop app instead of continuing with the browser (its Chrome by the way). Steps the Selenium webdriver is performing:
Visit https://company-name.slack.com
Fill in the email and password
Click Sign In button
Then this shows up:
This is not a normal browser alert but I'd like to get rid of it. I have tried the following:
webdriver.switch_to.alert.dismiss() Does not dismiss this pop-up
Adding the chrome_options.add_argument('--disable-default-apps') switch also doesn't prevent the pop-up from showing
Have tried the headless version as well, test failure suggests that the pop-up interrupted the flow.
This also has to work on CI servers so please if the solution didn't involve modifying developer machine then that would be wonderful.
Well, this is not an answer but a workaround. I managed to get around the default-app pop-up by continuing my operations in a new tab (But not before checking whether there is a pop-up in the first place). Psuedo code:
try
find_element_by_whatever(element_you_expect_after_login)
catch TimeoutException
webdriver.execute_script('window.open()')
webdriver.switch_to.window(webdriver.window_handles[1])
webdriver.get(url_which_required_login_in_the_first_place)
today I solved this problem, you can just simply install pynput module, after that :
from pynput.keyboard import Key, Controller
keyboard = Controller()
keyboard.press(Key.enter)
keyboard.release(Key.enter)
you can handle the open app popup in selenium with your keyboard.
try this chrome_options.add_argument("--disable-notifications") or chrome_options.add_argument("--disable-popup-window") or create a code for click the cancel button to do the next operation.
If this alert pops up every time you run the test, and the Cancel button is always in focus, then you can try to send the driver an ENTER.
I am very new to windows automation.I am automating wireshark using autopy.Now i need to open a file wireshark.I dont have swapy tool.I also dot want to do it in pyshark.I just want to try only in pywinauto.so i tried this way:
from pywinauto import application
print("Starting the proogram")
app=application.Application()
app.start_(r"C:\Program Files\Wireshark\Wireshark.exe")
win = app.window_(title_re = ".*Wireshark Network Analyzer.*")
win.MenuSelect("File->Open")
But i get this below error :
pywinauto.findwindows.WindowNotFoundError
Kindly help me out here with this guys.Thanks in advance
As I can see WireShark is starting up several seconds. You need waiting main window longer than default timeout (5 sec.).
win.wait('ready', timeout=15)
"Software Update" window can also be handled if it pops up:
if app.SoftwareUpdate.exists(timeout=10):
app.SoftwareUpdate.SkipThisVersion.click()
app.SoftwareUpdate.wait_not('visible') # just to make sure it's closed
win.wait('ready', timeout=15)
EDIT (2019, Jan, 21): the latest version of WireShark is built on Qt5 and current pywinauto example is maintained in the repo: examples/wireshark.py.
(old part of the answer below)
But in any case pywinauto doesn't support GDK widgets (even Windows UI Automation API doesn't support GDK apps). Menu is not available to pywinauto or UIA-based tools. You can deal with WireShark using workarounds only like so:
win.type_keys('%F{ENTER}') # Alt+F, Enter (it calls "&File->&Open" menu)
app.WiresharkOpenCaptureFile.FilenameEdit.set_edit_text('I can set text here')
app.WiresharkOpenCaptureFile.Open.click()
app.WiresharkOpenCaptureFile.wait_not('visible')
"Open" dialog is standard variation of Windows Open/Save dialog and pywinauto supports many controls on it.
To check which dialog is supported well by pywinauto use print_control_identifiers() method:
win.print_control_identifiers() # prints nothing
app.WiresharkOpenCaptureFile.print_control_identifiers() # prints a lot of controls
