# Item

A standard toolbar item type.

If you supply an action for an item object then it will be enabled by default.  You can override this behaviour by providing either a `shouldEnable` block or a `bindEnabled()` to enable or disable an item when required.

## Properties

[Core properties](core.md)

| Property   | Type (default)     |  Description |

| `image`  | `NSImage`    | the image to display on the toolbar item |


## Actions

[Core actions](core.md)

| Action    | Description |
|-----------|---------------------|
| `action`  | The block to call when the toolbar item is activated (eg. clicked)  |
| `shouldEnable` | Supply a callback block to be called to determine the enabled state of the item |
