The following code snippet should look for a window "Notes.txt - Notepad" and capture a screen-shot of that window.
import pyautogui
import win32gui
def screenshot(window_title="Notes.txt - Notepad"):
if window_title:
hwnd = win32gui.FindWindow(window_title, None)
if hwnd:
win32gui.SetForegroundWindow(hwnd)
x, y, x1, y1 = win32gui.GetClientRect(hwnd)
x, y = win32gui.ClientToScreen(hwnd, (x, y))
x1, y1 = win32gui.ClientToScreen(hwnd, (x1 - x, y1 - y))
im = pyautogui.screenshot(region=(x, y, x1, y1))
return im
else:
print('Window not found!')
else:
im = pyautogui.screenshot()
return im
im = screenshot('Calculator')
if im:
im.show()
The issues here is that no matter what I pass as window_title it always return:
Window not found!
When I print(hwnd)
it evaluate to 0
The issue lies here - hwnd = win32gui.FindWindow(window_title, None)
.
Replace it with win32gui.FindWindowEx(None, None, None, window_title)
and it should work.
EDIT:
win32gui.FindWindow(None, window_title)
should also work.
