# setOnMouseEntered(_:)

Specifies whether the receiver accepts mouseEntered(with:) events.

## Declaration

```swift
func setOnMouseEntered(_ flag: Bool)
```

## Parameters

- `flag`: doc://com.apple.documentation/documentation/Swift/true if the receiver accepts future doc://com.apple.appkit/documentation/AppKit/NSCursor/mouseEntered(with:) event messages; otherwise it ignores them.

## Discussion

Discussion Accepting mouseEntered(with:) event messages allows the cursor to be made the current cursor when the cursor enters a view’s cursor rectangle.
