# NSFullSizeContentViewWindowMask

When set, the content view consumes the full size of the window; it can be combined with other window style masks, but is only respected for windows with a title bar. Using this mask opts in to layer backing. Use the contentLayoutRect or contentLayoutGuide to lay out views underneath the title bar-toolbar area.

## Declaration

```occ
static const NSWindowStyleMask NSFullSizeContentViewWindowMask;
```
