Struct MacThumbnailCell 

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

Authentic macOS preview canvas cell (NSImageCell equivalent).

Provides a bounded canvas rectangle for rendering preview thumbnails, icons, or document previews with authentic macOS corner rounding, borders, and selection highlight styling.

Example

use egui_macview::{MacTheme, MacThumbnailCell};

let theme = MacTheme::default();

MacThumbnailCell::new()
    .theme(&theme)
    .square(32.0)
    .custom_draw(|painter, rect| {
        painter.circle_filled(rect.center(), 8.0, egui::Color32::BLUE);
    })
    .show(ui);
