开源鸿蒙 @Extend
@Extend
The @Extend decorator adds new attribute functions to preset components, such as <Text>, <Column>, and <Button>. You can use the @Extend decorator to quickly define and reuse the custom styles of a component.
@Extend(Text) function fancy(fontSize: number) {
.fontColor(Color.Red)
.fontSize(fontSize)
.fontStyle(FontStyle.Italic)
}
@Entry
@Component
struct FancyUse {
build() {
Row({ space: 10 }) {
Text("Fancy")
.fancy(16)
Text("Fancy")
.fancy(24)
}
}
}
NOTE: The @Extend decorator cannot be used in the struct definition of a custom component.
