Struct MacScrollView 

pub struct MacScrollView<'a> { /* private fields */ }

Authentic macOS AppKit Scroll View (NSScrollView equivalent).

Features zero-gutter content reservation (full viewport width/height), smooth hardware scroll clipping, virtual viewport computation, and interactive floating overlay scrollbars that smoothly fade out when inactive.

Example

use egui_macview::{MacScrollView, MacTheme};

let theme = MacTheme::default();

MacScrollView::new("log_scroll")
    .theme(&theme)
    .max_height(200.0)
    .show(ui, |content_ui| {
        for i in 0..50 {
            content_ui.label(format!("Log line {}", i));
        }
    });

Implementations

impl<'a> MacScrollView<'a>

pub fn new(id_source: impl Hash + Debug) -> Self

Creates a scroll view with state identified by id_source.

pub fn both(id_source: impl Hash + Debug) -> Self

Convenience constructor for both horizontal and vertical scrolling.

pub fn theme(self, theme: &'a MacTheme) -> Self

Injects dynamic theme to eliminate hardcoded metrics and colors.

pub fn horizontal(self, enabled: bool) -> Self

Enables or disables horizontal scrolling (default: false).

pub fn vertical(self, enabled: bool) -> Self

Enables or disables vertical scrolling (default: true).

pub fn auto_hide(self, auto_hide: bool) -> Self

Controls whether overlay scrollbars fade out when inactive (default: true).

pub fn max_height(self, max_h: f32) -> Self

Sets maximum height constraint in points.

pub fn max_width(self, max_w: f32) -> Self

Sets maximum width constraint in points.

pub fn min_scrolled_height(self, min_h: f32) -> Self

Sets minimum scrolled height in points.

pub fn min_scrolled_width(self, min_w: f32) -> Self

Sets minimum scrolled width in points.

pub fn with_offset(self, offset: &'a mut Vec2) -> Self

Binds directly to an external &mut Vec2 offset variable for programmatic control.

pub fn show<R>( self, ui: &mut Ui, content: impl FnOnce(&mut Ui) -> R, ) -> MacScrollViewOutput<R>

Renders the scrollable container and child content, overlaying authentic floating scrollbars.
