@Composable
@SubspaceComposable
fun MainPanel(
    modifier: SubspaceModifier = SubspaceModifier,
    shape: SpatialShape = SpatialPanelDefaults.shape
): Unit

Creates a SpatialPanel backed by the main Window content.

This panel requires the following specific configuration in the Android Manifest for proper sizing/resizing behavior:

<activity
android:configChanges="orientation|screenSize|screenLayout|smallestScreenSize>
<!--suppress AndroidElementNotAllowed -->
<layout android:defaultWidth="50dp" android:defaultHeight="50dp" android:minHeight="50dp"
android:minWidth="50dp"/>
</activity>

fun SpatialBox(
    modifier: SubspaceModifier = SubspaceModifier,
    alignment: SpatialAlignment = SpatialAlignment.Center,
    propagateMinConstraints: Boolean = false,
    content: @Composable @SubspaceComposable SpatialBoxScope.() -> Unit
): Unit

A layout composable that sizes itself to fit its content, subject to incoming constraints.

A layout composable with content. The SpatialBox will size itself to fit the content, subject to the incoming constraints. When children are smaller than the parent, by default they will be positioned inside the SpatialBox according to the alignment. For individually specifying the alignments of the children layouts, use the SpatialBoxScope.align modifier. By default, the content will be measured without the SpatialBox's incoming min constraints. If propagateMinConstraints is set to true, the min size set on the SpatialBox will also be applied to the content.

Note: If the content has multiple children, they might overlap depending on their positioning.

fun SpatialColumn(
    modifier: SubspaceModifier = SubspaceModifier,
    alignment: SpatialAlignment = SpatialAlignment.Center,
    content: @Composable @SubspaceComposable SpatialColumnScope.() -> Unit
): Unit

A layout composable that arranges its children in a vertical sequence.

For arranging children horizontally, see SpatialRow.

fun SpatialCurvedRow(
    modifier: SubspaceModifier = SubspaceModifier,
    alignment: SpatialAlignment = SpatialAlignment.Center,
    curveRadius: Dp = SpatialCurvedRowDefaults.curveRadius,
    content: @Composable @SubspaceComposable SpatialRowScope.() -> Unit
): Unit

A layout composable that arranges its children in a curved horizontal sequence.

fun SpatialExternalSurface(
    stereoMode: StereoMode,
    modifier: SubspaceModifier = SubspaceModifier,
    featheringEffect: SpatialFeatheringEffect = SpatialSmoothFeatheringEffect(ZeroFeatheringSize),
    content: @Composable @SubspaceComposable SpatialExternalSurfaceScope.() -> Unit
): Unit

A Composable that creates and owns an Android Surface into which the application can render stereo image content. This Surface is then texture mapped to the canvas, and if a stereoscopic StereoMode is specified, then the User will see left and right eye content mapped to the appropriate display. Width and height will default to 400 pixels if it is not specified using size modifiers.

Note that this Surface does not capture input events. It is also not currently possible to synchronize StereoMode changes with application rendering or video decoding. This composable currently cannot render in front of other panels, so movable modifier usage is not recommended if there are other panels in the layout, aside from the content block of this Composable.

@Composable
@SubspaceComposable
fun SpatialLayoutSpacer(modifier: SubspaceModifier = SubspaceModifier): Unit

A composable that represents an empty space layout. Its size can be controlled using modifiers like SubspaceModifier.width, SubspaceModifier.height, etc.

@Composable
@SubspaceComposable
fun SpatialPanel(
    intent: Intent,
    modifier: SubspaceModifier = SubspaceModifier,
    shape: SpatialShape = SpatialPanelDefaults.shape
): Unit

Creates a SpatialPanel and launches an Activity within it.

@Composable
@SubspaceComposable
fun SpatialPanel(
    modifier: SubspaceModifier = SubspaceModifier,
    shape: SpatialShape = SpatialPanelDefaults.shape,
    content: @Composable @UiComposable () -> Unit
): Unit

Creates a SpatialPanel representing a 2D plane in 3D space in which an application can fill content.

@Composable
@SubspaceComposable
fun SpatialPanel(
    view: View,
    modifier: SubspaceModifier = SubspaceModifier,
    shape: SpatialShape = SpatialPanelDefaults.shape
): Unit

Creates a SpatialPanel representing a 2D plane in 3D space in which an application can fill content.

@Composable
@SubspaceComposable
fun <T : View> SpatialPanel(
    factory: (Context) -> T,
    modifier: SubspaceModifier = SubspaceModifier,
    update: (T) -> Unit = {},
    shape: SpatialShape = SpatialPanelDefaults.shape
): Unit

Creates a SpatialPanel representing a 2D plane in 3D space where an Android View will be hosted.

The presented View is obtained from factory. The factory block will be called exactly once to obtain the View being composed into this panel, and it is also guaranteed to be executed on the main thread. Therefore, in addition to creating the View, the factory block can also be used to perform one-off initializations and View constant properties' setting. The factory inside of the constructor is used to avoid the need to pass the context to the factory. There is one View for every SpatialPanel instance and it is reused across recompositions. This View is shown effectively in isolation and does not interact directly with the other composable's that surround it. The update block can run multiple times (on the UI thread as well) due to recomposition, and it is the right place to set the new properties. Note that the block will also run once right after the factory block completes. SpatialPanel will clip the view content to fit the panel.

@Composable
@SubspaceComposable
fun SpatialRow(
    modifier: SubspaceModifier = SubspaceModifier,
    alignment: SpatialAlignment = SpatialAlignment.Center,
    content: @Composable @SubspaceComposable SpatialRowScope.() -> Unit
): Unit

A layout composable that arranges its children in a horizontal sequence. For arranging children vertically, see SpatialColumn.

@Composable
@SubspaceComposable
fun Volume(
    modifier: SubspaceModifier = SubspaceModifier,
    onVolumeEntity: (Entity) -> Unit
): Unit

A composable that represents a 3D volume of space within which an application can fill content.

This composable provides a Entity through the onVolumeEntity lambda, allowing the caller to attach child Jetpack XR Entities to it.
