# openGLContext

The NSOpenGLContext object associated with the receiver.

## Declaration

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

## Discussion

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.
