How to send SendKeys to Windows form in python script?

Question

I'm doing automation scripting in Python for my desktop application. In that I'm sending TAB key/any key to my windows form. But I'm not able to find handle of that Windows form in my Python script.

Here is the sample code snippet :

__author__ = 'juhis'

import SendKeys
import sys
import os
from Tkinter import *
import ctypes
import win32gui
import pywinauto

pwapp = pywinauto.application.Application()
whandle = pywinauto.findwindows.find_windows(title_re='Form1',class_name='WindowsForms10.Window.8.app.0.2bf8098_r13_ad1')[0]
window1 = pwapp.window_(handle=whandle)
window1.SetFocus()

SendKeys.SendKeys("""{PAUSE 2}""")
SendKeys.SendKeys("""{TAB 2}{PAUSE 2}{ENTER}""")

Please help me to figure out the issue.

-Thanks

Answer 1

The code can be re-written simpler:

import pywinauto

app = pywinauto.application.Application().connect(title_re='Form1')
Form1 = app.Window_(title_re='Form1', class_name='WindowsForms10.Window.8.app.0.2bf8098_r13_ad1')
Form1.SetFocus()
Form1.TypeKeys("{PAUSE 2}")
Form1.TypeKeys("{TAB 2}{PAUSE 2}{ENTER}")

TypeKeys automatically sets a focus to the Form1 and types the keys. SendKeys doesn't set a focus because it's not aware about the window. That's probably why it doesn't work with SendKeys.

[EDIT] Of course you need to run the script as Administrator.
