# BindedInputNumber

## 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

```python
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:

[ui-widgets-demos/input/004\_binded\_input\_number/src/main.py](https://github.com/supervisely-ecosystem/ui-widgets-demos/blob/master/input/004_binded_input_number/src/main.py)

### Import libraries

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

### Initialize `BindedInputNumber` widget

```python
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.

```python
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.

```python
app = sly.Application(layout=layout)
```
