Mini App Example

You can find this example in our Github repository:

ui-widgets-demos/controls/004_switch/src/main.py

Import libraries

import supervisely as sly
from supervisely.app.widgets import Container, Switch, OneOf, Text, Card

Initialize Switch widget

switch = Switch(
    on_content=Text("ON Content"),
    off_content=Text("OFF Сontent"),
)

Initialize OneOf widget to switch between Cards

switch_one_of = OneOf(switch)

Create app layout

Prepare a layout for app using Card widget with the content parameter and place widget that we've just created in the Container widget.

layout = Container(widgets=[
    Card(title="Switch", content=switch),
    Card(title="OneOf", content=switch_one_of),
])

Create app using layout

Create an app object with layout parameter.

app = sly.Application(layout=layout)
