根据进一步的测试，错误应该是出在border-type:None的指向不明确 位置为第58行：修改为 border-type: BorderType.None; 并加入import { BorderType } from "../../use/index.slint";

[ZhengLongBing]

还是不行

rust代码:

slint::include_modules!();

fn main() -> Result<(), slint::PlatformError>{
    let app=App::new()?;
    app.run().unwrap();
    Ok(())
}

slint代码:

import { SMenu } from "../../SurrealismUI/index.slint";
component App inherits Window{
    height: 600px;
    width: 1000px;
    SMenu {
        theme: Dark;     
    }
}

感谢您的提出，最终测试结果是这是一个存在于Slint内部的一个问题 原生Image组件的colorize属性无法接收in-out类型属性在states中的更改值 目前我正在进行修复，正式的0.3.1版本请耐心等待到12点前

[ZhengLongBing]

我刚刚也找出是下面这个代码错了问题，但我完全不理解这个错在哪里了

states [
    hover when area.has-hover:{
      icon.colorize : hover-icon-color;
    }
  ]

修复完后，可以详细讲讲吗？

[syf20020816]

colorize导致的问题None （None of the issues caused by colorize）

原因 reason

非同作用域的组件之间的状态判断变化的传递失效

The transmission failure of state judgment changes between components with different scopes

模拟代码

可以看到下方两个TouchArea中的是一摸一样的，唯一不同的是第一种将Outter提取到外部进行封装，但就是因为这个封装导致了状态传递的失效

It can be seen that the two TouchArea below are exactly the same, with the only difference being that the first method extracts the Outter externally for encapsulation, but it is precisely because of this encapsulation that the state transfer fails

component Outter inherits Rectangle{
  in-out property <brush> in-color : get-color();
  pure public function get-color()->brush {
      return #f60;
  }
    Image {
      colorize: in-color;
      source: UseIcons.icons.Avatar;
    }
}

export component App inherits Window {
  height: 400px;
  width: 200px;
  title: @tr("Slint + SurrealismUI + Rust");
  VerticalLayout {
    spacing: 20px;
    //none issue
    TouchArea {
      height: 200px;
      states [
          hover when self.has-hover: {
              o.in-color : #19c51f;
          }
      ]
      o:=Outter{}
    }
    //no issue
    TouchArea {
      height: 200px;
      states [
        hover when self.has-hover: {
            n.in-color : #19c51f;
        }
      ]
      n:=Rectangle {
        in-out property <brush> in-color : get-color();
        pure public function get-color()->brush {
          return #f60;
        }
        m:=Image {
          source: UseIcons.icons.Avatar;
          colorize: in-color;
        }
      }
    }
  }
}
