# reusesColumns

A Boolean that indicates whether the browser reuses matrix objects after their columns are unloaded.

## Declaration

```swift
var reusesColumns: Bool { get set }
```

## Discussion

Discussion When the value of this property is true, the NSMatrix objects aren’t freed when their columns are unloaded, so they can be reused.
