[NFBCS] Python Issue:

[charleseblack126 at gmail.com]

Afternoon:

 

I am running a Python script. I am creating a windows form and getting some
information, returning it to the console program and printing it and saving
it to a couple of programs. The problem is that the windows form will not
receive focus. I am a blind person using JAWS, 2026. Below is the base
program and the windows form. If someone could take a look at this and tell
me wha I am doing wrong, it would be appreciated.

 

Base:

 

# ----------------------------------------------

# Console Program to Launch the Tkinter Form

# ----------------------------------------------

 

# Import the custom Tkinter form

from user_form_module import UserForm

 

def main():

    print("Launching the form... Please fill it out.")

 

    # Create instance of the form

    form = UserForm()

 

    # Run the form and wait for user input (blocks here until submitted)

    name, role, comment = form.run()

 

    # Display returned results in console using correct f-string
interpolation

    print("Form completed! Values returned:")

    print(f"Name:    {name}")

    print(f"Role:    {role}")

    print(f"Comment: {comment}")

 

    # Save results to a text file

    with open("form_results.txt", "w") as f:

        f.write(f"Name: {name}\nRole: {role}\nComment: {comment}\n")

 

    print("Values saved to form_results.txt")

 

if __name__ == "__main__":

    main()

 

windows form:

 

# ------------------------------------------------------

# User Form Module (Windows Focus Bypass & JAWS Ready)

# ------------------------------------------------------

 

import tkinter as tk

from tkinter import ttk

import sys

 

class UserForm:

    def __init__(self):

        self.root = tk.Tk()

        self.root.title("User Information Form")

 

        self.name_value = ""

        self.role_value = ""

        self.comment_value = ""

 

        # Handle window close (X button or Alt+F4)

        self.root.protocol("WM_DELETE_WINDOW", self.on_close)

 

        ttk.Label(self.root, text="Enter your name:").pack(padx=10, pady=2)

        self.name_entry = ttk.Entry(self.root)

        self.name_entry.pack(padx=10, pady=2)

 

        ttk.Label(self.root, text="Select your role:").pack(padx=10, pady=2)

        self.role_combo = ttk.Combobox(self.root, values=["Admin", "User",
"Guest"])

        self.role_combo.pack(padx=10, pady=2)

 

        ttk.Label(self.root, text="Additional comments:").pack(padx=10,
pady=2)

        self.comment_entry = ttk.Entry(self.root)

        self.comment_entry.pack(padx=10, pady=2)

 

        ttk.Button(self.root, text="Submit",
command=self.submit_form).pack(padx=10, pady=10)

 

        # Schedule hard focus takeover once event loop begins

        self.root.after(150, self._force_windows_focus)

 

    def _force_windows_focus(self):

        if sys.platform.startswith("win"):

            import ctypes

            user32 = ctypes.windll.user32

            kernel32 = ctypes.windll.kernel32

 

            # Get thread IDs for current foreground window (the IDE) and
Python GUI window

            fg_hwnd = user32.GetForegroundWindow()

            fg_thread_id = user32.GetWindowThreadProcessId(fg_hwnd, None)

            app_thread_id = kernel32.GetCurrentThreadId()

 

            # Attach thread inputs temporarily so OS allows focus transfer

            if fg_thread_id != app_thread_id:

                user32.AttachThreadInput(app_thread_id, fg_thread_id, True)

                

                # Retrieve the actual Win32 window handle for the Tk root

                hwnd = user32.GetParent(self.root.winfo_id())

                if hwnd == 0:

                    hwnd = self.root.winfo_id()

 

                user32.SetForegroundWindow(hwnd)

                user32.SetFocus(hwnd)

                

                # Detach thread input

                user32.AttachThreadInput(app_thread_id, fg_thread_id, False)

 

        # Tkinter internal focus assignments

        self.root.lift()

        self.name_entry.focus_force()

 

    def submit_form(self):

        self.name_value = self.name_entry.get()

        self.role_value = self.role_combo.get()

        self.comment_value = self.comment_entry.get()

        self.root.quit()

        self.root.destroy()

 

    def on_close(self):

        self.root.quit()

        self.root.destroy()

 

    def run(self):

        self.root.mainloop()

        return self.name_value, self.role_value, self.comment_value

 

Thanks for any help.
