Types

Length Type

Name	Type	Description
Length	string \| number	Length unit. If the input is a number, use vp. If the input is a string, explicitly specify the unit, for example, ‘10px’, or specify the length in percentage, for example, ‘100%’.

Angle Type

Name	Type	Description
Angle	string \| number	Angle unit. If the input is a number, use deg. If the input is a string, use either of the following angle units: - deg: for example, ‘100deg’ - rad: for example, ‘3.14rad’

Point Type

Name	Type	Description
Point	[Length, Length]	Coordinates of a point. The first value is the x-axis coordinate, and the second value is the y-axis coordinate.

Color Type

The Color type used by component attribute methods is described as follows:

Name	Type	Description
Color	string \| number \| Color	Color information. If the input is a string, use rgb or rgba to specify the color. If the input is a number, use Hex format to specify the color. If the input is a Color enum, use a color value to specify the color. - ‘rgb(255, 255, 255)’ - ‘rgba(255, 255, 255, 1.0)’ - Hex format: 0xrrggbb, 0xaarrggbb, ‘#FFFFFF’ - Enum: Color.Black, Color.White

The supported Color enums are described as follows:

Color	Value	Illustration
Black	0x000000
Blue	0x0000ff
Brown	0xa52a2a
Gray	0x808080
Green	0x008000
Orange	0xffa500
Pink	0xffc0cb
Red	0xff0000
White	0xffffff
Yellow	0xffff00

ColorStop Type

ColorStop is used to describe the progressive color stop.

Name	Type	Description
ColorStop	[Color, number]	Type of the progressive color stop. The first parameter specifies the color value, and the second parameter specifies the ratio of 0 to 1.

Resource Type

The Resource type is used to reference resources for setting the value of a component attribute.

You can use $r or $rawfile to create a Resource object. For details, see Resource Access.

$r('belonging.type.name')

belonging : system or application resource. The value can be ‘sys’ or ‘app’.

type : resource type, which can be ‘color’, ‘float’, ‘string’, or ‘media’.

name : resource name, which is determined during resource definition.

$rawfile('filename')

filename : name of the file in resources/rawfile of the project.

Name	Type	Description
Resource	{ readonly id: [number]; readonly type: [number]; readonly params?: any[]; }	id: resource ID. type: resource type (enumerated value). params: optional parameters. After a Resource object is created using `$r` or `$rawfile`, modifying attribute values of the object is prohibited.

ResourceStr Type⁸⁺

Name	Type	Description
ResourceStr	string \| Resource	Resource string.

ResourceColor Type⁸⁺

Name	Type	Description
ResourceColor	Color \| number \| string \| Resource	Resource color.

Font Type⁸⁺

Name	Type	Description
Font	{ size?: Length; weight?: FontWeight \| number \| string; family?: string \| Resource; style?: FontStyle; }	Text style. size: font size. For the number type, use the unit fp. weight: font weight. For the number type, the value ranges from 100 to 900, at an interval of 100. The default value is 400. A larger value indicates a larger font weight. family: font family. Use commas (,) to separate multiple fonts. The priority of the fonts is the sequence in which they are placed. An example value is ‘Arial, sans-serif’. style: font style.

CustomBuilder Type⁸⁺

You can use CustomBuilder to define custom UI descriptions in component attribute methods.

Name	Type	Description
CustomBuilder	() => any	Builder of component attribute methods for defining custom UI descriptions. This type of method must be decorated by @Builder. For details, see @Builder.

@Component
struct dataTypeExample {
  build() {

        .backgroundColor(0xF9CF93).textAlign(TextAlign.Center)

      Text('45rad')
        .width(40).height(40)
        .rotate({ x: 0, y: 0, z: 1, angle: '45rad', centerX: '50%', centerY: '50%' })
        .fontColor(Color.White)
        .backgroundColor(0xF9CF93).textAlign(TextAlign.Center).margin({ top: 30 })

      Text('Point').fontColor(0xCCCCCC).fontSize(9).width('90%')
      Line().width(300).height(40).startPoint([0, 20]).endPoint([300, 20])
