# windowRef

The Carbon window reference associated with the window, creating one if necessary.

## Declaration

```swift
var windowRef: UnsafeMutableRawPointer { get }
```

## Discussion

Discussion You can use this property to create a WindowRef for a window containing a Carbon control. Subsequent accesses to this property get the existing WindowRef. You use a WindowRef to create a Carbon window reference for a Cocoa window; this assists the integration of Carbon and Cocoa code and objects. For more information see the MacWindows.h header file.
