# enableSetNeedsDisplay

A Boolean value that indicates whether the view responds to setNeedsDisplay().

## Declaration

```swift
var enableSetNeedsDisplay: Bool { get set }
```

## Discussion

Discussion If this value and the value of isPaused are true, the view behaves similarly to a UIView object, responding to calls to setNeedsDisplay(). In this case, the view’s internal draw loop is paused and updates are event-driven instead. The default value is false.
