Updating SearchBar.controls doesn't trigger it's rebuild #2874
Description
The example of SearchBar provided in the documentation opens a static dropdown. As it apparent from the controls that ListTile titles are obtained using a loop.
ft.ListTile(title=ft.Text(f"Color {i}"), on_click=close_anchor, data=i)
for i in range(10)
]
I am not very clear about the use of for loop inside controls. Can't find any syntax in the documentation.
I want the dropdown list to change based on text entered in the text filed. My approach was to update the ListTile controls during on_change event. However, not sure how to access the items in a loop and update the controls. My code is attached below. Please help.
from flet import *
import asyncio
class SearchApp(UserControl):
def __init__(self):
self.get_data = [
"design 1",
"design 2",
"design 3",
"design 4",
"design 5"
]
self.control_list = {}
self.filtered_list = []
super().__init__()
async def filter_table(self, e):
self.filtered_list = []
entered_text = self.control_list["search"].content.controls[0].value
for i in self.get_data:
if entered_text.lower() in i.lower() and i != "":
self.filtered_list.append(i)
# Update the TextButton here. Not sure how to do.
self.control_list["search"].content.controls[0].update()
print(self.filtered_list)
def search_ui(self):
_obj = Container(
bgcolor="white10",
border_radius=10,
height=50,
padding=10,
content=Row(
controls=[
SearchBar(
height=50,
on_change=lambda e: asyncio.run(self.filter_table(e)),
controls=[
TextButton(
text=item,
on_click=lambda e: print(item),
data=item
)
for item in self.filtered_list
]
)
]
)
)
self.control_list["search"] = _obj
return _obj
def build(self):
return Column(
controls=[
self.search_ui()
]
)
def main(page: Page):
page.window_width=500
page.horizontal_alignment = "center"
page.vertical_alignment = "top"
page.add(
SearchApp(),
)
page.update()
if __name__ == "__main__":
app(target=main)
You will notice that, my filtered list is being generated as expected. However, I am not able to update the SearchBar controls.
