Get other running processes window sizes in Python

This isn't as malicious as it sounds, I want to get the current size of their windows, not look at what is in them. The purpose is to figure out that if every other window is fullscreen then I should start up like that too. Or if all the other processes are only 800x600 despite there being a huge resolution then that is probably what the user wants. Why make them waste time and energy resizing my window to match all the others they have? I am primarily a Windows devoloper but it wouldn't upset me in the least if there was a cross platform way to do this.

I Modify someone code ,

This well help to run other application and get PID ,

import win32process
import subprocess
import win32gui
import time 
 
def get_hwnds_for_pid (pid):
  def callback (hwnd, hwnds):
    if win32gui.IsWindowVisible (hwnd) and win32gui.IsWindowEnabled (hwnd):
      _, found_pid = win32process.GetWindowThreadProcessId (hwnd)
      if found_pid == pid:
        hwnds.append (hwnd)
    return True
    
  hwnds = []
  win32gui.EnumWindows (callback, hwnds)
  return hwnds

# This the process I want to get windows size. 
notepad = subprocess.Popen ([r"C:\\Users\\dniwa\\Adb\\scrcpy.exe"]) 
time.sleep (2.0)

while True: 
  for hwnd in get_hwnds_for_pid (notepad.pid):
    rect = win32gui.GetWindowRect(hwnd)
    print(hwnd, "=>", win32gui.GetWindowText (hwnd))

    # You need to test if your resolution really get exactly because mine is doesn't . 
    # I use . 16:9 Monitor , Calculate the percent using this calculations , , (x * .0204082) and (y * .0115774)
    print((hwnd, (rect[2] - rect[0], rect[3] - rect[1])))
    x = rect[2] - rect[0]
    y = rect[3] - rect[1]
    print(type(x), type(y))
    time.sleep(1)

I updated the GREAT @DZinX code adding the title/text of the windows:

import win32con
import win32gui

def isRealWindow(hWnd):
    #'''Return True iff given window is a real Windows application window.'''
    if not win32gui.IsWindowVisible(hWnd):
        return False
    if win32gui.GetParent(hWnd) != 0:
        return False
    hasNoOwner = win32gui.GetWindow(hWnd, win32con.GW_OWNER) == 0
lExStyle = win32gui.GetWindowLong(hWnd, win32con.GWL_EXSTYLE)
if (((lExStyle & win32con.WS_EX_TOOLWINDOW) == 0 and hasNoOwner)
  or ((lExStyle & win32con.WS_EX_APPWINDOW != 0) and not hasNoOwner)):
    if win32gui.GetWindowText(hWnd):
        return True
return False

def getWindowSizes():

Return a list of tuples (handler, (width, height)) for each real window.
'''
def callback(hWnd, windows):
    if not isRealWindow(hWnd):
        return
    rect = win32gui.GetWindowRect(hWnd)
    text = win32gui.GetWindowText(hWnd)
    windows.append((hWnd, (rect[2] - rect[0], rect[3] - rect[1]), text ))
windows = []
win32gui.EnumWindows(callback, windows)
return windows

for win in getWindowSizes():
print(win)

I'm a big fan of AutoIt. They have a COM version which allows you to use most of their functions from Python.

import win32com.client
oAutoItX = win32com.client.Dispatch( "AutoItX3.Control" )

oAutoItX.Opt("WinTitleMatchMode", 2) #Match text anywhere in a window title

width = oAutoItX.WinGetClientSizeWidth("Firefox")
height = oAutoItX.WinGetClientSizeHeight("Firefox")

print width, height

Using hints from WindowMover article and Nattee Niparnan's blog post I managed to create this:

import win32con
import win32gui

def isRealWindow(hWnd):
    '''Return True iff given window is a real Windows application window.'''
    if not win32gui.IsWindowVisible(hWnd):
        return False
    if win32gui.GetParent(hWnd) != 0:
        return False
    hasNoOwner = win32gui.GetWindow(hWnd, win32con.GW_OWNER) == 0
    lExStyle = win32gui.GetWindowLong(hWnd, win32con.GWL_EXSTYLE)
    if (((lExStyle & win32con.WS_EX_TOOLWINDOW) == 0 and hasNoOwner)
      or ((lExStyle & win32con.WS_EX_APPWINDOW != 0) and not hasNoOwner)):
        if win32gui.GetWindowText(hWnd):
            return True
    return False

def getWindowSizes():
    '''
    Return a list of tuples (handler, (width, height)) for each real window.
    '''
    def callback(hWnd, windows):
        if not isRealWindow(hWnd):
            return
        rect = win32gui.GetWindowRect(hWnd)
        windows.append((hWnd, (rect[2] - rect[0], rect[3] - rect[1])))
    windows = []
    win32gui.EnumWindows(callback, windows)
    return windows

for win in getWindowSizes():
    print win

You need the Win32 Extensions for Python module for this to work.

EDIT: I discovered that GetWindowRect gives more correct results than GetClientRect. Source has been updated.

Check out the win32gui module in the Windows extensions for Python. It may provide some of the functionality you're looking for.
