# isPausable

A Boolean value that indicates whether the receiver is tracking work that you can pause.

```
var isPausable: Bool { get set }
```

## Discussion

By default, [`Progress`](/documentation/Foundation/Progress) objects aren’t pausable.

You typically use this property to communicate whether controls for pausing appear in a progress-reporting user interface. [`Progress`](/documentation/Foundation/Progress) itself doesn’t do anything with this property other than help pass the value from progress reporters to progress observers.

If an `NSProgress` is pausable, implement the ability to pause either by setting a block for the [`pausingHandler`](/documentation/Foundation/Progress/pausingHandler) property, or by polling the [`isPaused`](/documentation/Foundation/Progress/isPaused) property periodically while performing the relevant work.

It’s valid for the value of this property to change during the lifetime of an `NSProgress` object. By default, `NSProgress` is KVO-compliant for this property. It sends notifications on the same thread that updates the property.
