# onHover

Hide the window toolbar in full screen mode by default. It will reveal itself when the mouse moves into the area occupied by the menu bar.

## Declaration

```swift
static let onHover: WindowToolbarFullScreenVisibility
```

## Discussion

Discussion This has no effect if the toolbar is completely hidden, i.e. setting the visibility to hidden for windowToolbar placements using toolbarVisibility(_:for:) will cause the toolbar to remain completely hidden, even in full screen.
