# areaOfInterest(forMouse:)

Returns the type of area the mouse cursor is over.

## Declaration

```swift
func areaOfInterest(forMouse event: UIEvent) -> PDFAreaOfInterest
```

```swift
func areaOfInterest(forMouse event: NSEvent) -> PDFAreaOfInterest
```

## Discussion

Discussion The PDFAreaOfInterest enumeration defines the various area types. This method is for custom subclasses of the PDFView class. Use it if you override the NSResponder class’s mouseMoved(with:) method or related methods. Refer to Constants for the various values of the area-of-interest constants. Each of these constants contributes to the value of the PDFAreaOfInterest bit field.
