Introduction

BindedInputNumber widget in Supervisely is a user interface element that allows users to input two numerical values and customize their behavior using the proportional, min, and max properties. With the BindedInputNumber widget, users can fine-tune specific parameters within supervisely apps that require two numerical inputs, such as defining a rectangular region of interest by specifying the x and y coordinates and the width and height. The BindedInputNumber widget provides a convenient and flexible way to input and manage these values, with customizable behavior to ensure accurate and precise inputs.

Function signature

BindedInputNumber(
    width=256,
    height=256,
    min=1,
    max=10000,
    proportional=False,
    widget_id=None,
)

Mini App Example

You can find this example in our Github repository:

Import libraries

import supervisely as sly
from supervisely.app.widgets import Container, BindedInputNumber, Card

Initialize BindedInputNumber widget

binded_input_number = BindedInputNumber()

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="Binded Input Number",
    content=Container(widgets=[binded_input_number]),
)

layout = Container(widgets=[card])

Create app using layout

Create an app object with layout parameter.

app = sly.Application(layout=layout)
