Mini App Example

You can find this examples in our Github repository:

supervisely-ecosystem/ui-widgets-demos/status-elements/008_rate/src/main.py

Import libraries

import os

import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Button, Card, Container, Field, Input, InputNumber, Rate, 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()

In this guide, let's look at 3 examples of using the widget Rate in the one app.

Example 1

Initialize Rate widget

infos = ["oops", "disappointed", "normal", "good", "great"]
colors = ["#656565", "#F7BA2A", "#F6568E"]
rate = Rate(
    text_color="#656565",
    disabled=True,
    value=4,
    show_text=True,
    colors=colors,
    max=5,
    text_template="points",
)

Prepare InputNumber, Button and Card widgets we will use in this example

btn = Button("Enable / Disable")

card = Card("Disabled rate", content=Container([rate, btn]))

Add functions to control widgets from python code

@btn.click
def enable_btn_click():
    rate.enable() if rate.is_disabled else rate.disable()

Create app

Prepare a layout for app using Card widget with the content parameter.

layout = Container(widgets=[card])

Create an app object with layout parameter.

app = sly.Application(layout=layout)

Example 2

Initialize Rate widget

colors = ["#656565", "#F7BA2A", "#F6568E"]
rate = Rate(
    text_color="#656565",
    allow_half=True,
    value=4.2,
    show_text=True,
    colors=colors,
)

Prepare InputNumber, Button and Card widgets we will use in this example

btn = Button("Set value")
input_num = InputNumber(value=rate.get_value(), min=0, max=5, step=0.1)

card = Card("Set rating", content=Container([rate, input_num, btn]))

Add functions to control widgets from python code

@btn.click
def set_value_btn_click():
    new_value = input_num.get_value()
    rate.set_value(new_value)

Create app

Prepare a layout for app using Card widget with the content parameter.

layout = Container(widgets=[card])

Create an app object with layout parameter.

app = sly.Application(layout=layout)

Example 3

Initialize Rate widget

infos = ["oops", "disappointed", "normal", "good", "great"]
colors = ["#656565", "#F7BA2A", "#F6568E"]
rate = Rate(
    texts=infos,
    text_color="#656565",
    show_text=True,
    colors=colors,
    void_color="#F6568E",
)

Prepare Input, Field, Text, Button and Card widgets we will use in this example

text_input = Input()
text_field = Field(
    content=text_input,
    title="Enter texts for rate",
    description="Enter 5 string values separated by commas",
)
text = Text(status="text")
btn = Button("Set texts")


card = Card(
    "Rate",
    content=Container([rate, text, text_field, btn]),
)

Add functions to control widgets from python code

@rate.value_changed
def rate_changed(value):
    text.text = f"Rate value: {value} stars"


@btn.click
def set_texts_btn_click():
    text = text_input.get_value()
    if len(text.split()) != 5:
        return
    rate.set_texts(text.split(", "))

Create app

Prepare a layout for app using Card widget with the content parameter.

layout = Container(widgets=[card])

Create an app object with layout parameter.

app = sly.Application(layout=layout)
