Control.parent property

[ndonkoHenri]

Closes #952

• Issue TBF: The tiles created on_click of the first tile have no parent (None) although they all live in thesame ListView.

Test Code:

import flet as ft


def main(page: ft.Page):
    def handle_deletion_from_parent(e: ft.ControlEvent):
        tile = e.control.parent
        lv = tile.parent
        lv.controls.remove(tile)
        page.update()

    def handle_addition_to_parent(e: ft.ControlEvent):
        my_tile = ft.ListTile(
            trailing=ft.IconButton(
                ft.icons.DELETE,
                on_click=handle_deletion_from_parent,
                tooltip="Delete tile from parent",
            ),
            title=ft.Text(
                "I am a newly created tile. Click me too to add a new tile to my parent"
            ),
            on_click=handle_addition_to_parent,
        )
        lv = e.control.parent
        lv.controls.append(my_tile)
        page.update()

    page.add(
        ft.ListView(
            controls=[
                ft.ListTile(
                    trailing=ft.IconButton(
                        ft.icons.DELETE,
                        on_click=handle_deletion_from_parent,
                        tooltip="Delete tile from parent",
                    ),
                    title=ft.Text("Click me to add a new tile to my parent"),
                    on_click=handle_addition_to_parent,
                )
                for i in range(2)
            ]
        )
    )


ft.app(target=main)

That function where it's set is recursive, so control.parent will be set to a top most control which update() is called for.

What is your suggestion?

Issue TBF: The tiles created on_click of the first tile have no parent (None) although they all live in thesame ListView.

Resolved! Property works like a charm now - try the updated test code :)
