# discardCursorRects()

Invalidates all cursor rectangles set up using addCursorRect(_:cursor:).

## Declaration

```swift
func discardCursorRects()
```

## Discussion

Discussion You need never invoke this method directly; neither is it typically invoked during the invalidation of cursor rectangles.  NSWindow automatically invalidates cursor rectangles in response to invalidateCursorRects(for:) and before the view’s cursor rectangles are reestablished using resetCursorRects().  This method is invoked just before the view is removed from a window and when the view is deallocated.
