Top-level functions

Box

@Composable
fun Box(
    modifier: GlanceModifier = GlanceModifier,
    contentAlignment: Alignment = Alignment.TopStart,
    content: @Composable () -> Unit
): Unit

A layout composable with content.

By default, the Box will size itself to fit the content, unless a Dimension constraint has been provided. When the children are smaller than the Box, they will be placed within the box subject to the contentAlignment. When the content has more than one layout child, all of the children will be stacked on top of each other in the composition order.

Note for App Widgets: Box supports up to 10 child elements. Any additional elements will be truncated from the output.

Parameters
modifier: GlanceModifier = GlanceModifier

The modifier to be applied to the layout.
contentAlignment: Alignment = Alignment.TopStart

The alignment of children within the Box.
content: @Composable () -> Unit

The content inside the Box.

Column

@Composable
fun Column(
    modifier: GlanceModifier = GlanceModifier,
    verticalAlignment: Alignment.Vertical = Alignment.Top,
    horizontalAlignment: Alignment.Horizontal = Alignment.Start,
    content: @Composable ColumnScope.() -> Unit
): Unit

A layout composable with content, which lays its children out in a Column.

By default, the Column will size itself to fit the content, unless a Dimension constraint has been provided. When children are smaller than the size of the Column, they will be placed within the available space subject to horizontalAlignment and verticalAlignment.

Note for App Widgets: Column supports up to 10 child elements. Any additional elements will be truncated from the output.

Parameters
modifier: GlanceModifier = GlanceModifier

The modifier to be applied to the layout.
verticalAlignment: Alignment.Vertical = Alignment.Top

The vertical alignment to apply to the set of children, when they do not consume the full height of the Column (i.e. whether to push the children towards the top, center or bottom of the Column).
horizontalAlignment: Alignment.Horizontal = Alignment.Start

The horizontal alignment to apply to children when they are smaller than the width of the Column
content: @Composable ColumnScope.() -> Unit

The content inside the Column

    horizontalAlignment: Alignment.Horizontal = Alignment.Start,
    verticalAlignment: Alignment.Vertical = Alignment.Top,
    content: @Composable RowScope.() -> Unit
): Unit

A layout composable with content, which lays its children out in a Row.

By default, the Row will size itself to fit the content, unless a Dimension constraint has been provided. When children are smaller than the size of the Row, they will be placed within the available space subject to verticalAlignment and horizontalAlignment.

Note for App Widgets: Row supports up to 10 child elements. Any additional elements will be truncated from the output.

Parameters
modifier: GlanceModifier = GlanceModifier

The modifier to be applied to the layout.
horizontalAlignment: Alignment.Horizontal = Alignment.Start
