RadioTabs

Introduction

RadioTabs is a graphical user interface tool in Supervisely that allows users to group related widgets into tabs and switch between them using radio buttons.

Mini App Example

You can find this example in our Github repository:

ui-widgets-demos/layouts and containers/011_radio_tabs/src/main.py

Import libraries

import os

import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Card, Container, RadioTabs, Text

Init API client

First, we load environment variables with credentials and init API for communicating with Supervisely Instance:

load_dotenv("local.env")
load_dotenv(os.path.expanduser("~/supervisely.env"))

api = sly.Api()

Initialize RadioTabs widgets

tabs = RadioTabs(
    titles=["Info tab", "Success tab", "Warning tab", "Error tab"],
    contents=[
        Text("Info text", status="info"),
        Text("Success text", status="success"),
        Text("Warning text", status="warning"),
        Text("Error text", status="error"),
    ],
    descriptions=[
        "Tab with info text",
        "Tab with success text",
        "Tab with warning text",
        "Tab with error text",
    ],
)

many_tabs = RadioTabs(
    titles=[f"{i + 1} tab" for i in range(10)],
    contents=[Text(f"{i + 1} text", status="info") for i in range(10)],
    descriptions=[f"Tab with {i + 1} text" for i in range(10)],
)

Initialize Text widget to change text on widget

text = Text("Opened tab: Info tab")

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.

card = Card(
    title="Radio tabs",
    content=Container([tabs, text]),
)
card_many_tabs = Card(
    "Many radio tabs",
    content=many_tabs,
)

layout = Container(widgets=[card, card_many_tabs])

Create app using layout

Create an app object with layout parameter.

app = sly.Application(layout=layout)

Add functions to control widgets from python code

@tabs.value_changed
def show_opened_tab(value):
    text.text = f"Opened tab: {value}"
