Builds Dropzone

The code that drew it

A still frame holds a repeating animation at its first frame and a one-shot at its last, because a still of a moving thing is not reproducible. Run the gallery to review motion.

fn dropzone(_window: &mut Window, cx: &mut App) -> AnyElement {
    let theme = cx.theme().clone();
    // No single pointer position can produce all three states at once, so each
    // zone is pinned to the one it is here to show.
    stack(&theme)
        .w(px(560.0))
        .child(caption(&theme, "idle, accepting, refusing"))
        .child(
            row(&theme)
                .items_stretch()
                .child(
                    div().flex_1().child(
                        Dropzone::new("scene.dropzone.idle", "Drop files to attach")
                            .hint("PDF, PNG, or plain text")
                            .state(DropzoneState::Idle)
                            .on_files(|_, _, _| {}),
                    ),
                )
