```

## Discussion

This property lets you determine the region by which a window can be moved. The default value of this property is <doc://com.apple.documentation/documentation/Swift/false> if the view is opaque; otherwise, it is set to <doc://com.apple.documentation/documentation/Swift/true>. Subclasses can override this property to return different values based on the event.
