# ensureLayout(for:)

Forces the layout manager to perform layout for the specified text container if it hasn’t already.

```
func ensureLayout(for container: NSTextContainer)
```

## Parameters

`container`

The text container for which layout is performed.

## Discussion

The layout manager reserves the right to perform layout for larger ranges.  If noncontiguous layout is disabled, then the affected range is always effectively extended to start at the beginning of the text.
