# showWindow(_:)

Displays the window associated with the receiver.

```
@IBAction func showWindow(_ sender: Any?)
```

## Parameters

`sender`

The control sending the message; can be `nil`.

## Discussion

If the window is an [`NSPanel`](/documentation/AppKit/NSPanel) object and has its [`becomesKeyOnlyIfNeeded`](/documentation/AppKit/NSPanel/becomesKeyOnlyIfNeeded) flag set to <doc://com.apple.documentation/documentation/Swift/true>, the window is displayed in front of all other windows but is not made key; otherwise it is displayed in front and is made key. This method is useful for menu actions.

[`-  makeKeyAndOrderFront:`](/documentation/AppKit/NSWindow/makeKeyAndOrderFront(_:))
