TouchBoundsExpansion

value class TouchBoundsExpansion internal constructor(private val packedValue: Long)

Describes the expansion of a PointerInputModifierNode's touch bounds along each edges. See TouchBoundsExpansion factories and Absolute for convenient ways to build TouchBoundsExpansion.

Properties

start

val start: Int

The amount of pixels the touch bounds should be expanded along the start edge. When isLayoutDirectionAware is true, it's applied to the left edge when LayoutDirection is LayoutDirection.Ltr and vice versa. When isLayoutDirectionAware is false, it's always applied to the left edge.

top

val top: Int

The amount of pixels the touch bounds should be expanded along the top edge.

end

val end: Int

The amount of pixels the touch bounds should be expanded along the end edge. When isLayoutDirectionAware is true, it's applied to the left edge when LayoutDirection is LayoutDirection.Ltr and vice versa. When isLayoutDirectionAware is false, it's always applied to the left edge.

bottom

val bottom: Int

The amount of pixels the touch bounds should be expanded along the bottom edge.

isLayoutDirectionAware

val isLayoutDirectionAware: Boolean

Whether this TouchBoundsExpansion is aware of LayoutDirection or not. See start and end for more details.

Companion Object

Properties

val None = TouchBoundsExpansion(0)

Constant that represents no touch bounds expansion.

Methods

fun Absolute(
            left: Int = 0,
            top: Int = 0,
            right: Int = 0,
            bottom: Int = 0,
        ): TouchBoundsExpansion

Creates a TouchBoundsExpansion that's unaware of LayoutDirection. The left, top, right and bottom represent the amount of pixels that the touch bounds is expanded along the corresponding edge. Each value must be in the range of 0 to 32767 (inclusive).
