Detect if external process' window is flashing/blinking
To detect if an external process's window is flashing or blinking in Windows using Python, you can utilize the win32gui
and win32con
modules from the pywin32
package. Here's an example of how you can achieve this:
pythonimport win32gui
import win32con
# Specify the window title or class name of the target process
window_title = "Target Window Title"
window_class = "TargetWindowClass"
# Get the window handle based on the title or class name
window_handle = win32gui.FindWindow(window_class, window_title)
# Check if the window is flashing
is_flashing = win32gui.GetWindowLong(window_handle, win32con.GWL_EXSTYLE) & win32con.WS_EX_FLASHWINDOW
# Print the result
if is_flashing:
print("The window is flashing")
else:
print("The window is not flashing")
In this example, you need to specify the window_title
or window_class
variable with the title or class name of the target window you want to monitor. You can provide either the window title or class name, or both, depending on your specific requirements.
The FindWindow
function retrieves the window handle based on the provided title or class name. If the window is found, the GetWindowLong
function is used to retrieve the extended window style of the window. The WS_EX_FLASHWINDOW
constant is checked against the extended window style to determine if the window is flashing.
If the is_flashing
variable is True
, it means the window is flashing. Otherwise, if it is False
, the window is not flashing.
Make sure you have the pywin32
package installed (pip install pywin32
) to utilize the win32gui
and win32con
modules.
Note that this method detects if a window is flashing according to the extended window style, which may not capture all cases of window blinking.
