DpOffset

A two-dimensional offset using Dp for units.

To create a DpOffset, call the top-level function that accepts an x/y pair of coordinates:

val offset = DpOffset(x, y)

The primary constructor of DpOffset is intended to be used with the packedValue property to allow storing offsets in arrays or collections of primitives without boxing.

Unspecified

Cmn
Added in 1.1.0
val Unspecified: DpOffset

Represents an offset whose x and y are unspecified. This is usually a replacement for null when a primitive value is desired. Access to x or y on an unspecified offset is not allowed.

Zero

Cmn
Added in 1.0.0
val Zero: DpOffset

A DpOffset with 0 DP x and 0 DP y values.

Public constructors

Added in 1.8.0-alpha05
DpOffset(packedValue: Long)
Parameters
packedValue: Long

Long value encoding the x and y components of the DpOffset. Encoded values can be obtained by using the packedValue property of existing DpOffset instances.

Public functions

copy

Cmn 
fun copy(x: Dp = this.x, y: Dp = this.y): DpOffset

Returns a copy of this DpOffset instance optionally overriding the x or y parameter

minus

Cmn 
operator fun minus(other: DpOffset): DpOffset

Subtract a DpOffset from another one.

plus

Cmn 
operator fun plus(other: DpOffset): DpOffset

Add a DpOffset to another one.

packedValue

Cmn
Added in 1.8.0-alpha05
val packedValue: Long

Long value encoding the x and y components of the DpOffset. Encoded values can be obtained by using the packedValue property of existing DpOffset instances.

x

Added in 1.2.0
val x: Dp

The horizontal aspect of the offset in Dp
