## API Reference

> Source set: Common

```kotlin
public class WindowPosture(public val folds: List<WindowFold>)
```

Represents the overall physical posture of the window, aggregating all underlying hardware
folding features into a unified state.

Note that this describes the *window's* state, which may differ from the physical device's
posture. For example, if a foldable device is physically half-opened, but the current app is
in split-screen mode entirely on one side of the hinge, the window is not intersected by the
hinge and its posture will evaluate as `isFlat` == true.

#### Parameters

| | |
| --- | --- |
| folds | A list of all active [WindowFold](/jetpack-compose/androidx.compose.ui/ui/classes/UiMediaScope.WindowFold) features intersecting the window. |

## Properties

### isFlat

> Source set: Common

```kotlin
public val isFlat: Boolean
```

Whether the physical footprint of the window has no active bends disrupting its surface.

This gracefully evaluates to `true` for traditional non-foldable slab devices, foldables
that are completely opened to 180 degrees, and multi-window apps that do not span across
a hinge.

### isTabletop

> Source set: Common

```kotlin
public val isTabletop: Boolean
```

Whether the device is in a semi-open tabletop state, similar to a laptop.

This evaluates to `true` if the window is intersected by at least one horizontal,
half-opened hinge, logically splitting the horizontal display into top and bottom halves.
