:::tip[In plain words]
A thin bar with the actions of what you are looking at.
:::

The bar below the tabs of a code editor: widgets at the `start` (usually breadcrumbs) and at the `end` (buffer actions).

`ui.toolbar` · Category: [Navigation](https://albakore.github.io/pyzed/library/#navigation) · [Full reference →](https://albakore.github.io/pyzed/reference/ui/#toolbar)

**Code:**

```python
ui.toolbar(
    [ui.breadcrumbs([("file-code", "src"), "main.rs", "fn main"])],
    [ui.icon_button("search", on_search, size="sm"), ui.icon_button("sparkles", on_assist, size="sm")],
)
```

## When to use

- Between the tab bar and the editor, or at the top of any content view.

## Usage

```python
from pyzed import ui

ui.toolbar(
    [ui.breadcrumbs([("file-code", "src"), "main.rs", "fn main"])],
    [ui.icon_button("search", on_search, size="sm"), ui.icon_button("sparkles", on_assist, size="sm")],
)
```

## 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.

### Content

```python
pz.container(ui.toolbar([ui.breadcrumbs(["src", "main.rs"])]), width=400)
```

```python
pz.container(ui.toolbar([], [ui.icon_button("search", on_search, size="sm"),
                            ui.icon_button("sparkles", on_assist, size="sm")]), width=400)
```

```python
pz.container(ui.toolbar([ui.label("Preview")], [ui.button("Publish", on_publish, size="sm", variant="solid")],
                        height=40), width=400)
```

### States and events

```python
pz.container(ui.toolbar([ui.breadcrumbs(["src", "app.py"])], [ui.icon_button("play", on_press)],
                        center=ui.muted("Running…", size="sm")), width=440)
```

## Events

Toolbar 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.toolbar`
