TextComponent

@Immutable
open class TextComponent(textStyle: TextStyle = TextStyle.Default, lineCount: Int = TEXT_COMPONENT_LINE_COUNT, textOverflow: TextOverflow = TextOverflow.Ellipsis, margins: Insets = Insets.Zero, padding: Insets = Insets.Zero, val background: Component? = null, minWidth: TextComponent.MinWidth = MinWidth.fixed())

Uses Canvas to render text. This class utilizes TextMeasurer and supports the following:

  • multi-line text with automatic line breaking

  • text truncation

  • AnnotatedString

  • text rotation

  • text backgrounds (any Component)

  • margins and padding

Functions

open fun copy(style: TextStyle = this.textStyle, lineCount: Int = this.lineCount, textOverflow: TextOverflow = this.textOverflow, margins: Insets = this.margins, padding: Insets = this.padding, background: Component? = this.background, minWidth: TextComponent.MinWidth = this.minWidth): TextComponent

Creates a new TextComponent based on this one.

fun draw(context: DrawingContext, text: CharSequence, x: Float, y: Float, horizontalPosition: Position.Horizontal = Position.Horizontal.Center, verticalPosition: Position.Vertical = Position.Vertical.Center, maxWidth: Int = DEF_LAYOUT_SIZE, maxHeight: Int = DEF_LAYOUT_SIZE, rotationDegrees: Float = 0.0f)

Uses Canvas to draw this TextComponent.

fun getBounds(context: MeasuringContext, text: CharSequence? = null, maxWidth: Int = DEF_LAYOUT_SIZE, maxHeight: Int = DEF_LAYOUT_SIZE, rotationDegrees: Float = 0.0f, pad: Boolean = text == null): Rect

Returns the bounds (Rect) of this TextComponent for the given text and maximum dimensions. pad defines whether to extend text by such a number of blank lines that it has lineCount lines.

fun getHeight(context: MeasuringContext, text: CharSequence? = null, maxWidth: Int = DEF_LAYOUT_SIZE, maxHeight: Int = DEF_LAYOUT_SIZE, rotationDegrees: Float = 0.0f, pad: Boolean = text == null): Float

Returns the height of this TextComponent for the given text and maximum dimensions. pad defines whether to extend text by such a number of blank lines that it has lineCount lines.

fun getWidth(context: MeasuringContext, text: CharSequence? = null, maxWidth: Int = DEF_LAYOUT_SIZE, maxHeight: Int = DEF_LAYOUT_SIZE, rotationDegrees: Float = 0.0f, pad: Boolean = text == null): Float

Returns the width of this TextComponent for the given text and maximum dimensions. pad defines whether to extend text by such a number of blank lines that it has lineCount lines.
