I used a command "flet build windows" for make exe file with this code,
And run exe file. then cmd window is opened reapeatly per 5~6 second.

code is blow.

import flet as ft
import os

def main(page: ft.Page):

def change_text(e):
    text.value = textfield.value
    page.update()

def show_touch_keyboard(e):
    os.system("osk.exe")
    

textfield = ft.TextField(
                border_color = ft.colors.BLACK,
                text_align = "center",
                on_focus = show_touch_keyboard,
                on_change = change_text
)

text = ft.Text(
        value = "",
)


ct = ft.Column(
        controls = [
            textfield,
            text
        ]
    )


page.add(ct)

ft.app(target=main)

@jjjunehkim
Because the focus event of the textfield is triggered frequently and the virtual keyboard opens every time it is triggered. You can place a button in the application and click it to open the virtual keyboard once. In the meantime, you can search the processes and open the virtual keyboard once if the osk.exe application is not running.

Thank you so much for your solution.

I modified the code a little following your explanation as below,
Then I created exe file and ran exe file.

Although th cmd window did not open repeatedly, but opened once.

When executing a Python script, the cmd window did not open.
But when running the created exe file, the cmd window was opened.

What I really wanted was to put a virtual keyboard into the content of ft.Container, but that was difficult, so I tried to use the Windows virtual keyboard, but a problem occurred with the cmd window opening.

import flet as ft
import os

def main(page: ft.Page):

def change_text(e):
    text.value = textfield.value
    page.update()

def show_touch_keyboard(e):
    textfield.focus()
    os.system("osk.exe")
    
textfield = ft.TextField(
                border_color = ft.colors.BLACK,
                text_align = "center",
                # on_focus = show_touch_keyboard,
                on_change = change_text
)

text = ft.Text(
        value = "",
)

button = ft.ElevatedButton(
            text = "click",
            on_click = show_touch_keyboard
)

ct = ft.Column(
        controls = [
            textfield,
            text,
            button
        ]
    )

page.add(ct)

ft.app(target=main)

Then you can write your own virtual keyboard, turn it into a class and use it.

thank you for your reply.
I will check it .
I don't think it will be easy because my language, Korean, is written differently from English.
