TextDirection

enum TextDirection : Enum<TextDirection>

Base direction of a paragraph.

Direction affects which edge TextAlign.Start / End anchor to and which side justification leaves ragged. Glyph-level bidi reordering and Arabic shaping happen in the platform backends (Android and iOS shape natively; the JVM backend runs its own bidi + shaping pass), so the common layout layer only needs the paragraph's base direction.

Entries

Auto

Detect from the first strong directional character — Hebrew or Arabic content flips the paragraph to RTL automatically. The default, and the right choice for user-supplied content.

Ltr

Force left-to-right regardless of content.

Rtl

Force right-to-left regardless of content.

Properties

name

val name: String

ordinal

val ordinal: Int

Functions

resolve

fun TextDirection.resolve(text: String): TextDirection

Resolves TextDirection.Auto against actual text: the first strong directional character wins, mirroring the UAX#9 paragraph-level rule. Strings with no strong characters (digits, punctuation) read as LTR.

valueOf

fun valueOf(value: String): TextDirection

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

values

fun values(): Array<TextDirection>

Returns an array containing the constants of this enum type, in the order they're declared.
