title: "ThreePaneScaffoldValue"
description: "The adapted value of [ThreePaneScaffold]. It contains each pane's adapted value.
[ThreePaneScaffold] will use the adapted values to decide which panes should be displayed
and how they should be displayed. With other input parameters of [ThreePaneScaffold] fixed,
each possible instance of this class should represent a unique state of [ThreePaneScaffold]
and developers can compare two [ThreePaneScaffoldValue] to decide if there is a layout structure
change.

For a Material-opinionated layout, it's suggested to use [calculateThreePaneScaffoldValue] to
calculate the current scaffold value."

```kotlin
@ExperimentalMaterial3AdaptiveApi
class ThreePaneScaffoldValue(
    val primary: PaneAdaptedValue,
    val secondary: PaneAdaptedValue,
    val tertiary: PaneAdaptedValue
)
```


The adapted value of `ThreePaneScaffold`. It contains each pane's adapted value.
`ThreePaneScaffold` will use the adapted values to decide which panes should be displayed
and how they should be displayed. With other input parameters of `ThreePaneScaffold` fixed,
each possible instance of this class should represent a unique state of `ThreePaneScaffold`
and developers can compare two `ThreePaneScaffoldValue` to decide if there is a layout structure
change.

For a Material-opinionated layout, it's suggested to use `calculateThreePaneScaffoldValue` to
calculate the current scaffold value.

#### Parameters

| primary | `PaneAdaptedValue` of the primary pane of `ThreePaneScaffold` |
| secondary | `PaneAdaptedValue` of the secondary pane of `ThreePaneScaffold` |
| tertiary | `PaneAdaptedValue` of the tertiary pane of `ThreePaneScaffold` |
