**Code:**

```python
pz.row([
    ui.count_badge(3),
    ui.count_badge(42, tint="success"),
    ui.count_badge(120, tint="error"),
    pz.row([ui.icon_button("bell", on_press), ui.count_badge(7)], spacing=2, align="center"),
], spacing=16, align="center")
```

## When to use

- Next to an icon or tab to show how many unread items or errors there are.
- For text statuses use a [Badge](https://albakore.github.io/pyzed/library/badge/).

## Usage

```python
import pyzed as pz
from pyzed import ui

pz.row([
    ui.count_badge(3),
    ui.count_badge(42, tint="success"),
    ui.count_badge(120, tint="error"),
    pz.row([ui.icon_button("bell", on_press), ui.count_badge(7)], spacing=2, align="center"),
], spacing=16, align="center")
```

## Variants

:::note[About these captures]
Each capture is recorded by pyzed itself, off-screen at 2x, in One Dark or One Light to match this site's theme, and cropped to the component so it shows at its real size. The pointer hovers, presses or types into it; a component that does not react to the pointer cycles through a few themes. With reduced motion you see the first frame. Open **Code** under a capture to see the snippet that draws it; free names such as `on_save` stand for your own callbacks.

### Count

Above `max` it shows `max+`.

```python
ui.count_badge(3)
```

```python
ui.count_badge(42)
```

```python
ui.count_badge(120)
```

```python
ui.count_badge(12, max=9)
```

### Tint

```python
ui.count_badge(5, tint="success")
```

```python
ui.count_badge(5, tint="warning")
```

```python
ui.count_badge(5, tint="error")
```

### Next to an icon

```python
pz.row([ui.icon_button("bell", on_press), ui.count_badge(7)], spacing=2, align="center")
```

### States and events

With `show_zero=False` it draws nothing at 0 but keeps its place in the layout.

```python
pz.row([ui.icon_button("bell", on_press), ui.count_badge(0, show_zero=False)], align="center")
```

## Events

Count badge has no events of its own: it shows what you give it. Like every widget it also has the **18 common events** (`click`, `double_click`, `right_click`, `mouse_enter`, `drag`, `key_down`, `resize`…), attached with `.on(...)`: see [Events](https://albakore.github.io/pyzed/guides/events/) and [Events of every component](https://albakore.github.io/pyzed/library/events/).

## Properties and API

### `ui.count_badge`

```python
count_badge(count, *, tint='accent', max=99, show_zero=True, theme=None)
```

A round counter (notifications, problems…). Shows `99+` above `max`.

| Property | Default | Description |
| --- | --- | --- |
| `count` | *required* | The number. |
| `tint` | `"accent"` | Semantic color: `"accent"`, `"error"`, `"warning"`, `"success"`, `"info"` or a token. |
| `max` | `99` | Maximum before showing `N+`. |
| `show_zero` | `True` | With `False`, a count of 0 draws nothing. |
| `theme` | `None` | Theme to use instead of the current one (`pyzed.theme.current()`). |
