# openGLContext

The [`NSOpenGLContext`](/documentation/AppKit/NSOpenGLContext) object associated with the receiver.

```
var openGLContext: NSOpenGLContext? { get set }
```

## Discussion

If the receiver has no associated context object, a new `NSOpenGLContext` object is created. The new object is initialized with the receiver’s pixel format information.
