Can't Restore from repeatedly minimizing/restoring the app

[jhonielviloria]

Description

When running the application and repeatedly minimizing and restoring, there will be time that you cannot restore the application anymore.

Any flet app I do has this issue but here is a simple code example to reproduce the issue:

import flet as ft
import logging
logging.basicConfig(
    level=logging.DEBUG,
    format="%(asctime)s = %(levelname)s - %(filename)s - %(funcName)s - %(lineno)d - %(message)s",
)

def main(page: ft.Page):
    # Define a text field for user input
    user_input = ft.TextField(hint_text="Enter your name", width=200)

    # Define a function that shows an alert with a greeting
    def say_hello(e):
        if user_input.value:
            page.dialog = ft.AlertDialog(
                title="Greeting",
                content=ft.Text(f"Hello, {user_input.value}!"),
                actions=[ft.ElevatedButton("Close", on_click=lambda e: page.dialog.close())]
            )
            page.update()

    # Add the text field and a button to the page
    page.add(
        user_input,
        ft.ElevatedButton("Say Hello", on_click=say_hello)
    )

# Start the app
ft.app(target=main)

@Bronya0 @DoctorReid will be nice if you guys provide some more little info like the OS.

• Run by executable file:

  • Package in Github workflow, you can see the command here
  • Run on Windows 10

• Run by source

  • Python 3.11.3 AMD64
  • Windows 10

Don't know how to reproduce this problem exactly, but I met this problem in Flet 0.17.0 and 0.20.2.

Similar problem I found is this

[gpt9796]

me too and it's similar to issues #2266

[jhonielviloria]

I think the problem here is these values didn't get its default values during restore event:

"windowwidth":"160.0","windowheight":"39.0","windowtop":"-32000.0","windowleft":"-32000.0"

a workaround is to update these values during that event

    async def on_win_event(e):
        if e.data=='restore' and page.window_top<0:
            page.window_height = 720
            page.window_width = 1280
            page.window_top = 100
            page.window_left = 100
            await page.update_async()
    page.on_window_event = on_win_event

Let me know if it works for you or you have better solution.

I think the problem here is these values didn't get its default values during restore event:我认为这里的问题是这些值在恢复事件期间没有获得默认值：

"windowwidth":"160.0","windowheight":"39.0","windowtop":"-32000.0","windowleft":"-32000.0"

a workaround is to update these values during that event解决方法是在该事件期间更新这些值

    async def on_win_event(e):
        if e.data=='restore' and page.window_top<0:
            page.window_height = 720
            page.window_width = 1280
            page.window_top = 100
            page.window_left = 100
            await page.update_async()
    page.on_window_event = on_win_event

Let me know if it works for you or you have better solution.让我知道它是否适合您或者您有更好的解决方案。

非常感谢，问题解决了！！！！！！

@Bronya0 @DoctorReid will be nice if you guys provide some more little info like the OS.

This actually seems to happen on every OS.

Can you please try the latest pre-release and let know if the issue still happens?
