# becomeFirstResponder()

Notifies the receiver that it’s about to become first responder in its NSWindow.

## Declaration

```swift
func becomeFirstResponder() -> Bool
```

## Discussion

Discussion The default implementation returns true, accepting first responder status. Subclasses can override this method to update state or perform some action such as highlighting the selection, or to return false, refusing first responder status. Use the NSWindow makeFirstResponder(_:) method, not this method, to make an object the first responder. Never invoke this method directly.
