# NSCell.StyleMask

Constants for specifying what happens when a button is pressed or is displaying its alternate state.

```
struct StyleMask
```

## Overview

These contents are used by the [`highlightsBy`](/documentation/AppKit/NSButtonCell/highlightsBy) and [`showsStateBy`](/documentation/AppKit/NSButtonCell/showsStateBy) methods of [`NSButtonCell`](/documentation/AppKit/NSButtonCell).

## Topics

[`NSNoCellMask`](/documentation/AppKit/NSCellStyleMask/NSNoCellMask)

The button cell doesn’t change.

[`pushInCellMask`](/documentation/AppKit/NSCell/StyleMask/pushInCellMask)

The button cell “pushes in” if it has a border.

[`contentsCellMask`](/documentation/AppKit/NSCell/StyleMask/contentsCellMask)

The button cell displays its alternate icon and/or title.

[`changeGrayCellMask`](/documentation/AppKit/NSCell/StyleMask/changeGrayCellMask)

The button cell swaps the “control color” (the [`controlColor`](/documentation/AppKit/NSColor/controlColor) method of `NSColor`) and white pixels on its background and icon.

[`changeBackgroundCellMask`](/documentation/AppKit/NSCell/StyleMask/changeBackgroundCellMask)
