iced_native Event conflict with Message

[dryBranch]

I wrapped iced_native::event::Event in my Message to realize drag picture file to windows.

#[derive(Debug, Clone)]
enum Message {
    Start,
    EventOccurred(Event),
}

It's ok and nice work.

But, I can't add more wrapped variant in this Message, like this:

#[derive(Debug, Clone)]
enum Message {
    Start,
    EventOccurred(Event),
    OpenFile(String),
}

It doesn't work in view method, rustc tells me that it's not satisfied trait bound.

container(e).height(Length::Fill)
            .width(Length::Fill)
            .center_x()
            .center_y()
            .into()

The compiler give

the trait bound `iced_native::Element<'_, Message, iced_graphics::renderer::Renderer<iced_wgpu::backend::Backend, Theme>>: From<iced_native::widget::Container<'_, fn(String) -> Message {Message::OpenFile}, _>>` is not satisfied
the following other types implement trait `From<T>`:
  <iced_native::Element<'a, Message, Renderer> as From<&'a str>>
  <iced_native::Element<'a, Message, Renderer> as From<Column<'a, Message, Renderer>>>
  <iced_native::Element<'a, Message, Renderer> as From<Image<Handle>>>
  <iced_native::Element<'a, Message, Renderer> as From<Row<'a, Message, Renderer>>>
  <iced_native::Element<'a, Message, Renderer> as From<Tooltip<'a, Message, Renderer>>>
  <iced_native::Element<'a, Message, Renderer> as From<VerticalSlider<'a, T, Message, Renderer>>>
  <iced_native::Element<'a, Message, Renderer> as From<Viewer<Handle>>>
  <iced_native::Element<'a, Message, Renderer> as From<iced::widget::ProgressBar<Renderer>>>
and 15 others
required for `iced_native::widget::Container<'_, fn(String) -> Message {Message::OpenFile}, _>` to implement `Into<iced_native::Element<'_, Message, iced_graphics::renderer::Renderer<iced_wgpu::backend::Backend, Theme>>>`

How can I deal with it?

Rust is telling you your widget Message is a function, so you are most likely missing an argument somewhere.

What is e? How are you using the new OpenFile variant?

Oh really same as you said!!! I use the macro column! and input a Button with a function on_press(Message::OpenFile) make e. I forgot the Button and the error output is so wired XD. Thanks for your help😄 .
