Field.applyColour() 方法
更新字段以匹配块的颜色/样式。
如果字段的颜色取决于块的颜色,则非抽象子类可能希望实现此属性。系统会在相关时间(例如当父级块或渲染程序发生更改时)自动调用它。
如需了解详情,请参阅字段文档;如需查看示例,请参阅 FieldDropdown。
Signature:
applyColour(): void;
返回:
void

Subclasses can implement this method if the field's appearance depends on the block's color. This method is automatically called when the parent block or renderer changes. It takes no arguments and returns nothing (`void`). Detailed information can be found in the field documentation, with `FieldDropdown` as a practical example.\n"]]
